12 Best Noise Cancellation Software Tools for 2026

Background noise costs you deals. Your AE is mid-demo from a co-working space, and the prospect keeps asking them to repeat the pricing slide. Your VP of Sales is on a board-facing call, and someone's dog is barking on the other end. You've told the team to use Zoom's built-in noise cancellation software, but the results are inconsistent across 40 different home office setups.

The standard fix, telling everyone to buy a better headset, doesn't scale. People lose them, forget to charge them, or join calls from their laptop speakers anyway. The actual problem isn't individual hardware. It's that audio quality varies wildly across a distributed team, and there's no system-level fix in place.

That's where dedicated noise cancelling software comes in. But the category is crowded, ranging from free GPU-dependent tools to $8/user/month platforms with meeting transcription built in. Some tools work in real time during calls. Others clean up recordings after the fact. Picking the wrong type wastes budget and doesn't solve the problem.

What's inside

This guide covers the 12 best noise cancellation software tools for 2026, evaluated across pricing, platform support, real-time performance, and team deployment readiness. You'll find a comparison table, individual tool breakdowns with honest limitations, and guidance on when built-in options are good enough versus when you need a dedicated noise cancelling app.

Tools were selected based on G2 reviews, user forum feedback, hands-on evaluation, and real-world fit for distributed SaaS teams. The list includes free, freemium, and paid options.

TL;DR

• Krisp is the strongest all-around pick for SaaS teams that need noise suppression plus meeting transcription in one tool
• NVIDIA Broadcast and AMD Noise Suppression are free if you have compatible hardware, but they're GPU-dependent and not deployable across mixed-hardware teams
• Built-in noise suppression in Zoom, Teams, and Google Meet has improved significantly, and for many teams it's good enough without adding another tool
• For post-production audio cleanup (podcasts, webinars), Adobe Podcast and Audacity are the right picks, not real-time tools
• Free noise suppression software exists, but most options cap features or minutes; budget $5 to $8/user/month for reliable team-wide coverage

What is noise cancellation software

Noise cancellation software is a category of applications that use AI or digital signal processing to remove unwanted background sounds from audio input (microphone) or output (speakers) in real time. Most modern tools train deep learning models on thousands of noise profiles to distinguish human speech from everything else: keyboard clicks, dog barks, traffic, HVAC hum, and nearby conversations.

There are two distinct types. Real-time noise suppression software processes audio during live calls and meetings. Post-production tools clean up recorded audio after the fact. Knowing which you need narrows your shortlist immediately.

You'll see "noise cancellation" and "noise suppression" used interchangeably in marketing copy. Technically, noise cancellation refers to generating an inverse sound wave to cancel noise (common in hardware headphones using active noise control software principles). Noise suppression refers to digitally filtering noise from an audio signal. Software tools almost always use noise suppression, even when marketed as "noise cancellation."

There's also a hardware distinction. GPU-accelerated tools (NVIDIA Broadcast, AMD Noise Suppression) offload processing to the graphics card, resulting in lower latency and minimal CPU impact. Software-only tools (Krisp, Utterly) run on the CPU, which makes them hardware-agnostic but slightly more resource-intensive.

When evaluating mic noise suppression software or microphone noise cancelling software for your team, look for these core capabilities:

• Real-time processing with less than 20ms latency
• Bidirectional suppression (filters noise from both your mic and incoming audio)
• Compatibility with your team's communication apps (Zoom, Teams, Google Meet, Slack)
• Low CPU/GPU overhead that won't slow down other applications
• Privacy-first processing (on-device versus cloud-based)

When to use noise cancellation software

Remote and hybrid team calls

Your sales team is distributed. Some work from home offices, some from co-working spaces, some from kitchen tables. Background noise varies wildly from person to person and day to day. A dedicated noise cancellation app normalizes audio quality across the org without mandating hardware upgrades for every employee.

Sales demos and customer calls

Audio quality during a sales demo directly affects whether the message lands. If the prospect is distracted by background noise, they're not absorbing your value prop. This is where noise cancellation earns its ROI fastest, especially for teams running 20 to 50 calls per week. Equipping your reps with the right presales software alongside clean audio ensures every touchpoint is professional.

Webinars, podcasts, and recorded content

Post-production tools (Audacity, Adobe Podcast) clean up recordings after the fact. Real-time tools (Krisp, NVIDIA Broadcast) handle live scenarios. Know which you need before buying. Using a real-time tool for podcast editing, or a post-production tool for live calls, is a mismatch. If you're producing webinars at scale, pairing clean audio with a solid webinar platform makes the biggest difference.

Call centers and support teams

High-volume environments where agents sit close together need enterprise-grade noise suppression. Tools like SoliCall Pro and Krisp Enterprise are built for server-side deployment across dozens or hundreds of seats.

When built-in options are enough

Be honest with yourself here. If your team is under 15 people, everyone has a decent headset, and you primarily use Zoom or Teams, the built-in noise suppression may be sufficient. Don't buy a tool you don't need. Test the built-in options first, and upgrade only if audio quality complaints persist.

Noise cancellation software comparison table

Here's how all 12 tools compare across intent, differentiation, pricing, and ratings.

1. Krisp

Krisp is the most full-featured noise cancellation tool built for professional teams, combining real-time noise suppression with AI meeting transcription and accent localization in a single platform.

What sets Krisp apart is that it processes all audio locally on the device. No audio data leaves the machine, which matters for SaaS companies handling sensitive customer conversations or operating under compliance requirements. Beyond noise cancellation, Krisp has expanded into meeting productivity: transcription, AI-generated notes, and CRM integrations that push call summaries directly into Salesforce or HubSpot.

For a 50-person remote team, the math works out to roughly $400/month on the Pro plan. That's not trivial. But if it replaces both a noise cancellation tool and a separate meeting transcription tool, the consolidation often justifies the spend. If you're evaluating AI-powered meeting tools more broadly, our roundup of the best AI note-taking tools covers the transcription side in depth. The admin dashboard lets IT or RevOps deploy Krisp across the org, manage licenses, and monitor usage without touching individual machines.

The free tier caps usage at 60 minutes per day, which is tight for anyone running more than two calls. For occasional use, it's a solid way to test before committing.

Best for: SaaS sales teams and remote organizations that want noise cancellation plus meeting intelligence in one tool.

Key strengths

• Bidirectional noise cancellation for mic and incoming audio
• AI-powered meeting transcription and note-taking
• Works across all communication apps including Zoom, Teams, and Slack
• On-device processing for privacy (no audio sent to cloud)
• Team management dashboard for IT and admin deployment

Pricing: Free tier (60 min/day); Pro from $8/user/month; Enterprise custom pricing.

2. NVIDIA Broadcast

NVIDIA Broadcast is a free, GPU-accelerated noise cancellation and video enhancement tool that offloads all processing to NVIDIA RTX graphics cards, leaving your CPU untouched.

The performance is impressive. Because the RTX GPU handles the AI inference, noise removal runs with near-zero latency and minimal system impact. NVIDIA Broadcast also includes virtual background removal, auto-framing, and eye contact correction, making it a multi-purpose tool for video calls and streaming.

It works as a virtual microphone and virtual camera, meaning you select "NVIDIA Broadcast" as your input device in any communication app. Zoom, Teams, Google Meet, Discord, Slack: all work without additional configuration.

The catch is obvious. Only works with NVIDIA RTX 2060 or newer GPUs. If half your team uses MacBooks or machines with integrated graphics, this isn't a team-wide option. It's a strong individual tool for engineers or team members who happen to have RTX hardware, but it fails the "deploy across 50 mixed machines" test.

Best for: Teams where most members have NVIDIA RTX GPUs (common in engineering-heavy SaaS companies and content creation teams).

Key strengths

• GPU-accelerated noise removal with minimal CPU impact
• Virtual background removal and auto-framing included
• Works as a virtual microphone and camera for any app
• Free with compatible hardware, no subscription
• Low latency suitable for real-time calls and streaming

Pricing: Free (requires NVIDIA RTX 2060 or newer GPU).

3. AMD Noise Suppression

AMD Noise Suppression is AMD's answer to NVIDIA Broadcast. It's built directly into the AMD Adrenalin driver suite, so there's no separate application to install or manage.

The setup is as simple as it gets: open AMD Adrenalin Software, toggle noise suppression on. It activates as a system-level audio filter that works with any communication app. Originally targeted at gamers who needed to suppress keyboard and fan noise during voice chat, it works equally well for work calls.

The feature set is narrower than NVIDIA Broadcast. You get noise suppression only, with no virtual backgrounds, no auto-framing, and no video enhancements. For teams that just need clean audio without the extras, that simplicity is an advantage, not a limitation.

Like NVIDIA Broadcast, the hardware requirement is the constraint. AMD Radeon GPU required. No Mac support. No integrated graphics support. If your team runs mixed hardware, this tool covers only a portion of your people.

Best for: Users with AMD Radeon GPUs who want free noise suppression without installing additional software.

Key strengths

• Integrated into AMD Adrenalin driver suite, no separate install
• GPU-accelerated processing for low latency
• Simple toggle activation with minimal configuration
• Free with AMD hardware, no subscription
• Works with any voice communication application

Pricing: Free (requires compatible AMD Radeon GPU).

4. SoliCall Pro

SoliCall Pro is an enterprise-grade noise cancellation tool designed for call centers and high-volume phone operations where dozens of agents share an open-plan floor.

Unlike consumer-focused tools, SoliCall offers server-side deployment through SoliCall PBXMate. This means you can apply noise cancellation centrally across an entire call center without installing software on individual agent machines. For IT teams managing 50 to 200 agent seats, this centralized approach removes the deployment headache entirely.

SoliCall also includes echo cancellation, which is a common problem in call center environments where agents use headsets of varying quality. The profile-based noise learning adapts to each user's specific environment over time, improving suppression accuracy the longer an agent uses it. Teams evaluating call center tooling may also want to explore outbound call tracking software to pair with their noise suppression stack.

The trade-off is pricing transparency. SoliCall doesn't publish prices on its website. You'll need to contact their sales team for quotes, which are typically structured per seat or per server. For smaller teams (under 10 agents), the overhead of an enterprise sales process may not be worth it. Krisp's Enterprise plan is often a simpler path for mid-size teams.

Best for: SaaS companies with dedicated support or sales call center teams (10+ agents in a shared or open-plan environment).

Key strengths

• Server-side and client-side deployment options
• Echo cancellation in addition to noise suppression
• Profile-based noise learning adapts to each environment
• Call recording and quality monitoring capabilities
• Enterprise licensing and dedicated support

Pricing: Custom pricing; contact SoliCall for quotes. Typically licensed per seat or per server.

5. Adobe Podcast (Enhance Speech)

Adobe Podcast Enhance Speech is a browser-based, AI-powered tool that cleans up audio recordings after the fact. Upload a file, and it removes background noise, echo, and room reverb while enhancing voice clarity.

This is not a real-time noise cancellation app. You can't use it during a live call. It's purpose-built for post-production: cleaning up podcast episodes, webinar recordings, or video content where the original audio was recorded in a noisy environment.

The workflow is drag-and-drop simple. No software install required. Upload your audio file in the browser, wait for processing, and download the cleaned version. The AI handles noise, echo, and reverb in a single pass, which saves time compared to manually applying multiple filters in a tool like Audacity.

Adobe currently offers Enhance Speech for free during its beta period. The quality of the output is strong enough that many podcast producers use it as their primary cleanup tool, even over dedicated audio editors. The limitation is processing time: longer files take longer, and there's no batch processing for multiple episodes.

Best for: Marketing teams producing podcasts, webinar recordings, or video content where audio was recorded in less-than-ideal conditions. If you're also looking for tools to help create and repurpose that content, check out our list of the best content creation software tools.

Key strengths

• Browser-based with no software install required
• AI-powered voice enhancement beyond just noise removal
• Free during beta period
• Simple drag-and-drop workflow
• Handles echo, reverb, and background noise in one pass

Pricing: Free (currently in beta as part of Adobe's AI audio tools).

6. Audacity

Audacity is the long-standing open-source audio editor with built-in noise reduction capabilities. It's been around since 2000, and it remains one of the most widely used free audio tools available.

Audacity's noise reduction works differently from AI-based tools. You select a segment of "silence" that contains only the background noise, capture a noise profile, then apply reduction across the entire recording. This manual approach gives you fine-grained control over how aggressively noise is removed, but it requires understanding of the tool and some trial-and-error to get right.

This is not a real-time tool. It's a post-production editor for cleaning up recordings: podcasts, training videos, webinar archives, and customer interview recordings. For teams on a zero budget who need to clean up audio occasionally, Audacity handles the job well. For teams that need to process audio regularly or at volume, the manual workflow becomes a bottleneck.

The learning curve is moderate. Non-technical users will need 30 to 60 minutes to learn the noise reduction workflow. The community documentation is extensive, with step-by-step guides for common tasks.

Best for: Teams that need to clean up recorded audio (podcasts, training videos, webinar recordings) on a zero budget.

Key strengths

• Completely free and open-source
• Full audio editing suite beyond just noise reduction
• Cross-platform support for Windows, macOS, and Linux
• Large community and extensive documentation
• Plugin support for additional audio effects

Pricing: Free.

7. OBS Studio

OBS Studio is an open-source broadcasting and recording tool with built-in audio filters, including AI-based noise suppression via RNNoise and a traditional noise gate.

OBS wasn't designed as a noise cancellation tool. It's a streaming and recording platform that happens to have solid audio filtering built in. The RNNoise suppression filter uses a recurrent neural network to remove background noise in real time, and it performs well for its price point (free). The noise gate filter mutes audio below a configurable volume threshold, which handles consistent low-level hum.

The practical use case for SaaS teams: OBS can output a virtual audio device that feeds cleaned audio into any communication app. You'd set up OBS with your microphone, apply the noise suppression filter, then select the OBS virtual output as your mic in Zoom or Teams. It works, but the setup is more involved than tools like Krisp or Utterly.

If your team already uses OBS for recording product walkthroughs, webinars, or internal training videos, adding noise suppression is a zero-cost upgrade. If you don't already use OBS, installing it just for noise cancellation is overkill.

Best for: Content creators, streamers, and teams that already use OBS for recording or streaming and want noise suppression without adding another tool.

Key strengths

• Free and open-source with active development
• Built-in RNNoise suppression filter using AI
• Noise gate and compressor filters for granular audio control
• Virtual camera and audio output works with Zoom and Teams
• Highly customizable with a large plugin library

Pricing: Free.

8. Utterly

Utterly is a lightweight, free noise cancelling application that does one thing: creates a virtual microphone to filter background noise in real time. No meeting transcription. No video features. No account required. Just noise cancellation.

The setup takes about two minutes. Install the app, select the virtual mic in your communication app, and background noise is suppressed. The simplicity is the selling point. For individual users or small teams that want a free, no-fuss noise cancellation tool without the complexity of Krisp or the hardware requirements of NVIDIA Broadcast, Utterly fills the gap.

CPU usage is low, and the app runs quietly in the background. There are no usage caps, no premium tier to upsell you into, and no data collection.

The trade-off is what you don't get. No team management features. No admin dashboard. No bidirectional noise cancellation (it only filters your outgoing mic audio, not incoming audio from other participants). And the long-term development activity is unclear, so you're taking a small risk on whether the tool will be maintained and updated over time.

Best for: Individual users or small teams that want a simple, free noise cancellation tool without complexity.

Key strengths

• Free with no usage limits or premium gates
• Simple setup and minimal user interface
• Virtual microphone works with any communication app
• Low CPU usage that runs quietly in the background
• No account or sign-up required to use

Pricing: Free.

9. Noise Blocker

Noise Blocker is a lightweight noise suppression tool that creates a virtual microphone device on Windows. It uses AI to filter out background noise from your mic input before it reaches your communication app.

The interface is minimal: on/off toggle, microphone selection, and a sensitivity slider. That's it. For Windows users who want a simple, low-overhead noise suppression tool for occasional use, it handles the basics without demanding attention.

The one-time purchase model is notable. Most noise cancellation tools either require a subscription or lock you into specific hardware. Noise Blocker offers a free version with basic functionality and a full version for a one-time payment of approximately $9.99. For budget-conscious teams that don't need Krisp's meeting intelligence features, this pricing model is appealing.

The limitations are real. Windows only. No Mac or Linux support. No team deployment features. No admin dashboard. No bidirectional suppression. If you're evaluating tools for a 30-person distributed team with mixed operating systems, Noise Blocker covers only a subset of your people.

Best for: Windows users who want a minimal, low-overhead noise suppression tool for occasional use.

Key strengths

• Simple, single-purpose tool with minimal interface
• Virtual microphone approach works with any app
• Low resource usage on system performance
• One-time purchase option with no subscription
• No ongoing account management required

Pricing: Free version available; one-time purchase ~$9.99 for full version.

10. Noise Gator

Noise Gator is an open-source noise gate application. It's important to understand what that means: it's not AI-based noise cancellation. A noise gate mutes all audio below a certain volume threshold. Sound above the threshold passes through. Sound below it gets cut.

This works well for eliminating constant, low-level background noise like fan hum, air conditioning, or a distant road. It does not handle variable noise well. A dog barking, a conversation in the next room, or a door slamming will pass through if they're loud enough to exceed the threshold.

The setup requires manual threshold tuning. You need to find the sweet spot where your voice passes through but background noise doesn't. This takes experimentation, and the ideal threshold changes if your environment changes (moving from a quiet room to a noisier one).

For technical users comfortable with manual configuration who want a free, open-source noise gate, Noise Gator fills a niche. For everyone else, AI-based tools like Krisp or Utterly handle complex noise environments with far less effort.

Best for: Technical users who want a free, open-source noise gate and are comfortable with manual threshold configuration.

Key strengths

• Free and open-source with no licensing costs
• Simple noise gate functionality for consistent noise
• Works as a virtual audio device on your system
• No AI processing means lower resource usage
• Good for steady, low-level background noise

Pricing: Free.

11. Zoom built-in noise suppression

Zoom's built-in noise suppression has improved significantly over the past two years. It now offers four suppression levels (auto, low, medium, high) accessible under Settings > Audio. For teams already on Zoom as their primary meeting platform, this may be sufficient without adding another tool to the stack.

The "high" setting aggressively filters background noise and handles common disruptors like keyboard typing, dog barking, and nearby conversations. The trade-off: on low-quality microphones, the high setting can occasionally clip voice audio, making speech sound slightly compressed or muffled. The "auto" setting adapts dynamically and tends to work well for most users.

The biggest advantage is zero deployment overhead. Every Zoom user already has this. No additional software, no virtual microphone configuration, no IT involvement. It applies automatically to all Zoom calls on desktop and mobile.

The biggest limitation is scope. Zoom's noise suppression only works within Zoom. If your team uses Slack Huddles, Google Meet, phone dialers, or Discord alongside Zoom, you still need a separate tool for those channels. For teams standardized on Zoom for all voice communication, this built-in option is often good enough. You can explore Zoom's interface yourself through this interactive Zoom demo.

Best for: Teams already using Zoom as their primary meeting platform who want noise suppression without adding another tool.

Key strengths

• No additional software or cost required
• Adjustable suppression levels including auto, low, medium, and high
• Applied automatically to all Zoom calls
• No virtual microphone setup or configuration needed
• Works on desktop and mobile platforms

Pricing: Included with all Zoom plans.

12. Microsoft Teams noise suppression

Microsoft Teams includes AI-powered noise suppression that filters background noise in real time during calls and meetings. It uses deep neural networks trained to distinguish human speech from noise, and it processes both incoming and outgoing audio.

Like Zoom's option, Teams noise suppression is built in and requires no additional setup. You'll find the setting under Settings > Devices > Noise suppression, with adjustable levels. The AI model handles common office and home noises well: typing, fans, pets, and ambient chatter.

For organizations already standardized on Microsoft Teams and the broader Microsoft 365 suite, this is the path of least resistance. No additional vendor relationship, no additional cost, no additional tool for IT to manage. It works on desktop, web, and mobile. See how the Microsoft Teams interface looks in action.

The limitation mirrors Zoom's: it only works within Teams. If your team uses multiple communication platforms, Teams noise suppression covers only a portion of your audio interactions. The suppression quality also varies by device and environment, with better results on higher-quality microphones.

Best for: Organizations already standardized on Microsoft Teams who want noise suppression without additional tools.

Key strengths

• Built into Teams with no install or additional cost
• AI-powered suppression using deep neural networks
• Adjustable suppression levels for different environments
• Works on desktop, web, and mobile clients
• Supports both incoming and outgoing audio filtering

Pricing: Included with all Microsoft Teams plans.

How to choose the right noise cancellation software

Real-time vs. post-production

This is the first decision. Do you need noise cancellation during live calls, or are you cleaning up recordings? Real-time tools (Krisp, NVIDIA Broadcast, Utterly, built-in platform options) handle calls. Post-production tools (Adobe Podcast, Audacity) handle recordings. Buying the wrong type wastes your budget.

Platform coverage

Does the tool work across all the communication apps your team uses? Virtual-microphone-based tools (Krisp, Utterly, NVIDIA Broadcast) work with any app. Built-in options (Zoom, Teams) only work within their own platform. If your team uses three different communication tools, a platform-locked option covers only a third of your audio.

Team deployment

Can IT or RevOps roll this out across 50 machines without touching each one? Krisp offers an admin dashboard with centralized license management. SoliCall Pro offers server-side deployment. Free tools like Utterly and Noise Blocker require individual setup on every machine. At scale, that difference matters.

Hardware requirements

GPU-accelerated tools (NVIDIA Broadcast, AMD Noise Suppression) are free but require specific hardware. If your team uses MacBooks, these are off the table entirely. For mixed-hardware teams, which describes most remote-first SaaS companies, stick with CPU-based or platform-built-in options.

Privacy and data handling

Does audio leave the device? Krisp processes everything locally. NVIDIA Broadcast and AMD Noise Suppression also process on-device. Browser-based tools like Adobe Podcast upload audio for cloud processing. For companies handling sensitive customer conversations, on-device processing is the safer choice.

Cost at scale

A tool that's $8/user/month across 50 users is $4,800/year. Compare that to the built-in options already included in your Zoom or Teams subscription. Make sure the upgrade is worth the delta. If built-in suppression handles 80% of your audio quality issues, spending $4,800 to fix the remaining 20% may not pencil out.

Conclusion

Start by testing whether your existing platform's built-in noise suppression is sufficient. For many small to mid-size teams with decent headsets, it is. If it's not, Krisp is the strongest all-around option for SaaS teams that need noise cancellation and meeting intelligence without adding two separate tools. If your team has compatible GPUs, NVIDIA Broadcast or AMD Noise Suppression are free and effective. For post-production cleanup, Adobe Podcast and Audacity handle the job well.

Once your team's audio is clean and professional, the next question is whether the rest of your buyer experience matches that quality. If prospects are still sitting through static screen shares instead of experiencing your product on their own terms, the audio fix is only half the story. An interactive demo lets buyers explore your product at their own pace, turning passive presentations into hands-on experiences.
