Noise Canceling Apps for Remote Work: 10 Tools, Ranked

The best noise canceling apps for remote work in 2026 are Krisp (best all-rounder with AI transcription), NVIDIA Broadcast (free with RTX hardware), and CrystalSound (best for privacy and "My Voice Only" filtering). Most real-time tools run $8-$16/user/month; free options exist but require specific hardware or only work post-production. Below: 10 apps ranked by use case, platform, and price.

63% of knowledge workers struggle with concentration due to workplace noise, per Jabra's 2024 survey of 2,800 professionals across six countries. Open offices routinely reach 50-70 dB, well above the threshold where cognitive performance starts to degrade.

A noise canceling app filters out keyboard clicks, HVAC hum, dog barks, and street noise before they reach Zoom, Teams, or any other call. Real-time tools use a virtual microphone; post-production tools clean up recorded audio after the fact.

Key Takeaways

1. Real-time tools like Krisp and CrystalSound work across all communication apps via a virtual microphone; built-in options (Zoom, Teams) only filter within their own platform.
2. Free hardware-dependent tools (NVIDIA Broadcast, AMD Noise Suppression) can't be deployed across mixed-hardware teams.
3. CrystalSound reports that 67% of employees admit to being distracted during online meetings; dedicated noise cancellation reduces this friction without requiring hardware upgrades.

How to Evaluate Noise Canceling Apps

• Real-time vs. post-production: Real-time tools filter noise live during calls; post-production tools clean up recordings. Only the former helps you on a call right now.
• Platform coverage: Virtual-microphone tools (Krisp, CrystalSound) work with any app. Built-in options (Zoom, Teams) only cover one platform.
• Hardware requirements: Some free tools (NVIDIA Broadcast) require a specific GPU and cannot be standardized across a mixed team.
• Team vs. individual: If you're deploying to a team, look for admin dashboards, seat management, and enterprise billing. Solo users can keep it simple.

Comparison Table

1. Krisp

Best for distributed teams that need noise cancellation and meeting intelligence in one tool

Krisp is the most widely deployed AI noise cancellation tool for remote teams, and it earns that position by doing more than just filtering background noise. It adds bidirectional noise cancellation (your mic and incoming audio from other participants), meeting transcription, AI-generated notes and action items, and accent localization for Indian, Filipino, LatAm, and South African speakers. All audio processing runs on-device, so no audio is ever sent to Krisp's servers.

The virtual microphone approach means Krisp works across any communication app: Zoom, Teams, Slack, Discord, and 800+ applications. IT admins get a team management dashboard for deploying and managing seats without asking each user to self-configure. The MCP integration (Claude, ChatGPT, Cursor) lets you pull meeting notes directly into your AI workflows.

Where Krisp falls short is cost. The free plan is gone as of 2026, replaced by a 7-day free trial. If your team only needs noise suppression and doesn't want to pay for transcription features, CrystalSound or ClaerityAI cover the core use case at a lower price.

Pros

1. Bidirectional filtering covers both your microphone and incoming audio from other participants
2. Meeting transcription and AI notes add clear ROI beyond noise filtering alone
3. On-device processing keeps your audio private: nothing is sent to the cloud

Cons

1. No longer offers a permanent free plan: 7-day trial only
2. More expensive than pure noise-only tools if you don't need transcription
3. Mobile app does not include noise cancellation: desktop (Windows, Mac) only for real-time filtering

Pricing

• Core: $8/mo/user (billed annually) or $16/mo/user (monthly): includes AI note-taker, unlimited noise cancellation, 5 GB storage
• Advanced: $15/mo/user (annual) or $30/mo/user (monthly): adds Salesforce integration, unlimited accent conversion, 30 GB storage
• Enterprise: Custom pricing
• All plans come with a 7-day free trial, no credit card required.

2. NVIDIA Broadcast

Best for content creators and streamers with an NVIDIA RTX GPU

NVIDIA Broadcast offloads all noise processing to your NVIDIA RTX graphics card, which means your CPU stays available for other work and latency stays low. The app installs as a virtual microphone and virtual camera, so it integrates with any communication or streaming app on Windows.

Beyond noise suppression, NVIDIA Broadcast bundles virtual background removal, auto-framing, and the newer Studio Voice (beta) feature that makes your microphone sound like it was recorded in a treated studio room. For streamers or creators who already have RTX hardware and don't want to pay a monthly subscription, this is a compelling zero-cost option.

The hard constraint is hardware: you need an NVIDIA RTX 2060 or newer GPU. If any team member runs a different GPU or works on a Mac, NVIDIA Broadcast isn't deployable across your full team. It's best used as an individual tool, not a team standard.

Pros

1. Zero subscription cost for anyone already running RTX hardware
2. GPU offloading means no CPU performance hit during heavy workloads
3. Video enhancements (background removal, auto-framing) bundled at no extra cost

Cons

1. Windows only, with no Mac or Linux support
2. Requires a specific NVIDIA RTX GPU, so it can't be standardized across mixed-hardware teams
3. No bidirectional filtering: only your outgoing microphone is processed

Pricing

• Free: requires NVIDIA RTX 2060 or newer GPU. No subscription, no tiers.

3. CrystalSound

Best for privacy-conscious remote workers who need bidirectional noise filtering

CrystalSound runs a deep neural model entirely on your device, filtering both your outgoing microphone audio and the incoming audio from other call participants. This on-device approach means your voice never leaves your machine for processing, which matters for teams in legal, healthcare, or other privacy-sensitive environments.

The standout feature is "My Voice Only," which isolates your voice specifically and mutes other nearby speakers. If you're working from a shared office, coffee shop, or coworking space where a colleague might wander into frame mid-call, this prevents their voice from appearing in your audio stream at all. CrystalSound also bundles a screen and audio recorder with optional cloud storage, which makes it a useful all-in-one tool for async teams.

The Premium tier includes unlimited noise cancellation plus screen recording for $12/mo/user (or $96/user/year). A free tier covers basic noise cancellation with some limitations. The Elite tier (coming soon) will add meeting transcription and performance analytics, positioning CrystalSound as a more affordable Krisp alternative for teams that don't need accent conversion.

Pros

1. "My Voice Only" feature isolates your voice in shared or crowded environments
2. On-device AI processing ensures complete audio privacy
3. Works with all conferencing tools via virtual microphone and speaker

Cons

1. Some users report minor voice "leakage" during very loud background noise events
2. Setup process feels more complex than single-purpose tools
3. Transcription and analytics features still in development (Elite tier not yet live)

Pricing

• Free tier: Basic noise cancellation with usage limits
• Premium: $12/mo/user (monthly) or $96/user/year: includes unlimited noise cancellation, screen recording, and cloud storage
• Elite (coming soon): $228/user/year: adds meeting transcription, performance analysis, and risk analysis
• Starts with a free 7-day trial on Premium.

4. Adobe Podcast Enhance

Best for quickly cleaning up a recorded audio file without installing any software

Adobe Podcast Enhance Speech is a browser-based AI audio filter that takes a recorded audio file and makes it sound like it was captured in a soundproofed studio. Upload a file, and within seconds you get back a version with background noise removed, voice levels balanced, and clarity improved. No download, no account, no configuration.

This is a post-production tool only: it can't filter noise during live calls. For remote workers who record async video messages, training walkthroughs, or client presentations and want broadcast-quality audio without learning a full editor, it fills a genuine gap. Audacity and OBS Studio handle more complex multi-track editing; Adobe Podcast Enhance handles the "quick cleanup before I send this video" use case.

The tool is currently free as part of Adobe's beta AI audio toolkit. File size and length limits may apply, and you're uploading audio to Adobe's servers, which is worth noting if your content is sensitive. Adobe processes and deletes submitted audio according to their standard data policy.

Pros

1. Zero cost and zero install: the lowest barrier to entry of any tool on this list
2. Produces broadcast-quality results from casual recordings with no technical skill required
3. Works on any device with a browser, with no OS limitation

Cons

1. Post-production only: cannot filter noise during live calls
2. Requires uploading audio to Adobe's cloud (privacy consideration for sensitive content)
3. File length and size limits apply during beta; not suitable for long-form production

Pricing

• Free (currently in free beta). No credit card required.

5. Audacity

Best for teams that need free, professional-grade post-production audio editing

Audacity has been around since 2000 and remains the go-to free audio editor for podcasters, trainers, and remote teams cleaning up recorded content. Its noise reduction works by capturing a "noise profile" from a silent section of your recording, then applying that profile to remove the matching frequencies across the full file. The manual process requires trial-and-error but gives you fine-grained control over how aggressively noise is removed.

The newer AI-powered noise suppressor via the OpenVINO plugin brings Audacity closer to real-time capability, though it remains primarily a post-production tool. The plugin ecosystem (VST, AU, LADSPA, LV2) lets you add compression, EQ, de-essing, and dozens of other effects without spending anything. For teams on a zero budget that need to clean up recordings regularly, Audacity handles the job without the ongoing cost of Adobe Audition or iZotope RX.

The learning curve is real. Non-technical users typically need 30-60 minutes to get comfortable with the noise reduction workflow. The interface has improved over recent versions but remains more complex than newer alternatives like Adobe Podcast Enhance.

For occasional one-off cleanup, Adobe's web tool is the faster path. For regular, detailed editing work, Audacity's full suite is worth learning.

Pros

1. Completely free and open-source under the GPL-2.0 license, with no tiers or feature locks
2. Full audio editing suite beyond noise reduction: EQ, compression, multi-track recording, format conversion
3. Runs on Windows, macOS, and Linux with extensive community documentation

Cons

1. Steep learning curve: the noise profiling workflow requires 30-60 minutes to learn
2. Post-production only, not useful for filtering noise on live calls
3. Dated interface criticized as cluttered compared to newer tools

Pricing

• Free: open-source with no premium tiers. All features available to everyone at no cost.

6. OBS Studio

Best for streamers and content creators who want built-in AI noise suppression alongside recording tools

OBS Studio is primarily a streaming and recording platform, but it includes solid built-in audio filtering that makes it useful as a noise suppression tool for remote workers who are already in the OBS ecosystem. The RNNoise suppression filter uses a recurrent neural network to remove background noise in real time. The noise gate filter mutes audio below a configurable volume threshold, handling consistent low-level hum like fans or HVAC.

Once configured, OBS outputs a virtual microphone and virtual camera that any communication app can pick up. This means your Zoom or Teams call picks up your OBS-processed audio directly. The setup overhead is higher than dedicated noise cancellation tools, but if you're already using OBS for recording or streaming, there's no reason to add another subscription on top.

The latest stable release continues to receive active updates from a community funded by YouTube, NVIDIA, AMD, and Twitch, among others. For teams and individuals who don't need team management or transcription features, OBS represents a capable zero-cost option with a real AI noise model behind it.

Pros

1. Free and open-source with active development and regular updates
2. AI-powered RNNoise suppression performs competitively with entry-level paid tools
3. Virtual camera and mic output works with Zoom, Teams, Slack, and any other app

Cons

1. High setup overhead compared to dedicated noise tools: not plug-and-play
2. Designed for streaming and recording, not specifically for call audio filtering
3. No team management, no admin dashboard, no enterprise deployment

Pricing

• Free: open-source with no premium tiers.

7. Utterly

Best for Mac users who want the simplest free real-time noise cancellation with no account required

Utterly does exactly one thing: creates a virtual microphone that filters background noise in real time. Install it, select Utterly as your mic in any communication app, and background noise is suppressed without any account, sign-up, or usage cap. For individual Mac users who want noise cancellation with zero friction and zero cost, there's nothing simpler on this list.

CPU usage is minimal and the app runs quietly in the background without asking for your attention. Unlike Krisp's 7-day trial or CrystalSound's tiered feature set, Utterly imposes no limits on how much you use it.

The trade-offs matter if you have a team or a cross-platform environment. Utterly is macOS only and filters only your outgoing microphone audio, not incoming audio from other participants. There's no team management, no admin dashboard, and the long-term development trajectory is unclear compared to well-funded commercial tools.

Pros

1. Zero cost and no account: install and use immediately without any sign-up friction
2. No usage caps or premium tiers, with full functionality available to everyone
3. Low CPU impact that runs quietly without interrupting your work

Cons

1. macOS only, with no Windows or Linux support
2. Unidirectional filtering only: your outgoing microphone is processed, incoming audio from others is not
3. Long-term maintenance activity is unclear, adding development risk for a free tool

Pricing

• Free: no usage limits, no premium tier.

8. ClaerityAI

Best for teams that want a longer free trial before committing to a noise suppression subscription

ClaerityAI offers real-time noise suppression with a simple interface and a 30-day free trial: the longest trial period of any tool on this list. Krisp gives you 7 days; CrystalSound gives you 7 days; ClaerityAI gives you a full month to evaluate whether the tool fits your workflow. For teams that want to validate noise suppression ROI before budgeting for it, that runway is meaningful.

The tool integrates directly with Zoom, Teams, and other major conferencing platforms. Customizable noise reduction settings let you tune the suppression level for different environments: a busy coffee shop requires different settings than a home office with occasional traffic noise.

ClaerityAI has fewer public reviews and less community documentation than Krisp or CrystalSound. If third-party validation and a large user community matter to your evaluation, the established alternatives have a clear edge. For teams prioritizing trial length and simple integrations over brand recognition, ClaerityAI is worth testing.

Pros

1. 30-day free trial, the longest on this list, giving teams a full month to validate ROI
2. Customizable suppression settings for different noise environments
3. More affordable than Krisp for teams that only need noise suppression without transcription

Cons

1. Fewer public reviews and less community documentation than market leaders
2. No meeting intelligence features (transcription, notes, or action items)
3. Less established brand, which adds some adoption risk for enterprise teams

Pricing

• Pricing: Contact claerityai.com for current rates
• 30-day free trial for individuals and teams, no credit card required.

9. Zoom Noise Suppression

Best for Zoom-only teams who want noise cancellation without any additional software or cost

Zoom includes AI-powered noise suppression built into every meeting, no extra tool required. You get four adjustable suppression levels (auto, low, medium, high), and Zoom applies them automatically to both your microphone and incoming audio. The feature works on desktop and mobile: Windows, macOS, iOS, and Android.

For teams already standardized on Zoom where every meeting flows through one platform, adding a separate noise cancellation tool introduces unnecessary complexity and cost. Zoom's built-in suppression has improved over the past two years and covers the common use case: keyboard typing, light HVAC, and ambient office noise. It won't match the performance of dedicated tools in very noisy environments, but it performs well enough for most distributed teams.

The constraint is clear: Zoom noise suppression only works in Zoom. If your team also uses Slack huddles, Google Meet, or Webex, the built-in feature doesn't carry over. In mixed-platform environments, a virtual microphone tool like Krisp or CrystalSound provides consistent suppression across everything.

Pros

1. Zero additional cost for any Zoom subscriber, including the free Basic plan
2. Requires no installation, configuration, or virtual microphone setup
3. Works on all major desktop and mobile platforms within the Zoom ecosystem

Cons

1. Only works in Zoom, without filtering noise in Slack, Google Meet, or other platforms
2. Less aggressive noise suppression than dedicated tools in loud or complex environments
3. No team-level reporting on audio quality or noise levels

Pricing

• Included with all Zoom plans: Basic (free), Pro, Business, and Enterprise.

10. Microsoft Teams Noise Suppression

Best for enterprise teams on Microsoft 365 who want bidirectional AI filtering at no added cost

Microsoft Teams uses deep neural networks to filter both your outgoing microphone and incoming audio from other participants during calls and meetings. The models are trained to distinguish human speech from noise at a fine-grained level: keyboard clicks, background conversations, HVAC, and environmental sounds are all addressed. Noise suppression is available across Windows, macOS, iOS, Android, and the web client.

For organizations already running Microsoft 365, this is a zero-marginal-cost feature built into a platform you're already paying for. It processes audio bidirectionally, which puts it ahead of unidirectional tools like NVIDIA Broadcast and Utterly in terms of call clarity from both sides. Microsoft continues to invest in improving the underlying models as part of its broader Copilot AI integration.

The limitation mirrors Zoom's: Teams noise suppression only works inside Teams. If your organization uses Slack, Zoom, or Webex for any meetings, those calls are unaffected. Feature availability also varies by Microsoft 365 license tier: some advanced audio settings are restricted to E3 or E5 plans.

Pros

1. Included in Microsoft 365 at no added cost for existing subscribers
2. Bidirectional neural network filtering covers both outgoing and incoming audio
3. Available across all major platforms including mobile and web

Cons

1. Only works in Microsoft Teams, with no benefit in Zoom, Slack, or other platforms
2. Cannot be used as a virtual microphone for other communication apps
3. Some advanced audio features require higher Microsoft 365 license tiers (E3/E5)

Pricing

• Included with Microsoft Teams as part of any Microsoft 365 plan. No separate pricing.

How to Choose the Right Noise Canceling App

• If you're on a mixed-platform team (Zoom + Slack + Teams): choose a virtual microphone tool (Krisp, CrystalSound, or ClaerityAI) that works across every app, not one locked to a single platform.
• If you already have an NVIDIA RTX GPU and only need Windows support: NVIDIA Broadcast is the obvious choice: no subscription, no trade-off.
• If privacy is critical: CrystalSound's on-device processing keeps audio off external servers entirely.
• If you need the lowest barrier to entry for post-production cleanup: Adobe Podcast Enhance requires no install and is currently free.
• If you're already fully standardized on Zoom or Teams: use the built-in suppression before adding another tool to your stack.

Emerging Trends in Noise Canceling Apps

• AI transcription bundled with noise cancellation: Krisp's move to combine real-time audio filtering with meeting notes signals where the market is heading: noise suppression as infrastructure for meeting intelligence, not a standalone feature.
• On-device processing as a privacy standard: CrystalSound and Krisp both default to local audio processing. As teams become more privacy-aware, cloud-side audio processing is becoming a harder sell.
• Bidirectional filtering as the new baseline: Single-direction tools only filter your outgoing mic. The expectation is shifting toward filtering incoming audio too, particularly in open-plan or café environments where the entire call sounds noisy.

Conclusion

The right noise canceling app depends on what you already have and what you actually need. Krisp is the strongest all-around choice for distributed teams: bidirectional filtering, on-device privacy, and meeting intelligence in one tool.

If your team is already on Zoom or Microsoft 365, start with the built-in suppression before adding anything. For Mac users who want free real-time filtering with zero setup, Utterly is the simplest path. And for teams that want to take their time evaluating, ClaerityAI's 30-day trial is long enough to make a confident decision.
