CrystalSound

CrystalSound is a desktop app for reducing call noise, recording meetings and enhancing audio files. It best suits people who want those tools together on Windows, macOS or Linux. Its broad feature set is appealing, but uncertainty around plan limits and several prices makes it a harder choice for anyone who needs predictable costs.

Overview

CrystalSound combines call cleanup with meeting capture and post-recording tools. It can reduce background noise from both sides of a conversation, record screen and audio, and produce meeting minutes, keywords and insights. That range makes it more useful for recurring meetings than a tool focused only on cleaning a single recording.

The company says audio and VoiceID are processed locally and are not sent off-device or accessible to NamiTech. That is a meaningful privacy advantage for voice data. CrystalSound also collects app version, settings, email, operating system, usage times and which apps use its virtual speaker or microphone. Paid users can disable usage tracking in settings. The company says its Vercel and Firebase services are certified under ISO 27001, ISO 27017, ISO 27018, SOC 1, SOC 2 and SOC 3.

Key features

Bidirectional noise cancellation targets background noise from both the user and the other party, a useful distinction for calls where incoming audio is also difficult to hear. My Voice Only uses a registered voice profile to suppress unwanted noise or other people’s voices. Those capabilities make CrystalSound a stronger fit for conversations than for users who only need to polish an existing audio file.

Screen and bidirectional audio recording, meeting minutes, keywords and meeting insights extend the app into meeting documentation. Audio enhancement supports MP3, WAV and FLAC recordings, while voice effects include pitch shift, reverb and robotic effects. The effects add creative options, but the listed set is narrower than a full audio production suite.

The homepage displays logos for OBS, Discord, Loom, Slack, Teams, Skype and Meet, positioning CrystalSound for use alongside conference and creator apps. It also offers echo removal and voice isolation.

Pricing

CrystalSound uses a freemium model with a free Starter plan and a 7-day trial. Starter costs nothing, but its feature allowance and limits are not defined, so it is difficult to know whether it covers regular use or simply provides a way to try the app.

Elite (Coming soon) is priced at $228 a year, billed USD/User/Year. It includes unlimited noise cancellation, meeting transcription, performance analysis, risk analysis and areas of improvement. Per-user billing makes the annual commitment relevant for teams, and the plan’s coming-soon status means it is not a dependable choice for an immediate purchase.

Premium has custom pricing, billed USD/User/Year. Its features include unlimited noise cancellation and cloud call recording (Preview); automatic titles, smart meeting minutes, and keyword and sentiment analysis are unavailable. Enterprise also has custom pricing and includes unlimited noise cancellation, bidirectional noise cancellation, secure offline screen recording, bulk order discounts and VDI support. Its offline recording and VDI support make it the more relevant option for organizations with those requirements, while custom pricing means costs need to be established before adoption.

Subscriptions have a 30-day money-back guarantee. After that period, refunds are not issued for unused time. Readers comparing a paid plan should weigh that cutoff alongside the per-user annual term where it applies.

Platforms

CrystalSound is a desktop product for Windows, macOS and Linux. The installation guide specifies Windows 10 (20H1), supported recent macOS versions, and Linux with glibc 2.28 or later; each system requires 4 GB RAM. The three-system support is useful for mixed desktop environments, but older machines or unsupported macOS releases may not meet the stated requirements.

Who it's for

CrystalSound is a good fit for people who want to improve live call audio and keep recordings, summaries or analysis in the same desktop workflow. Its local processing claim may also matter to users who prefer audio and voice-profile processing to remain on-device. It is less suitable for buyers who need a clearly bounded free tier, published Premium or Enterprise costs, or a standalone audio editor rather than meeting-focused tools.

Pros and cons

• Pro: Bidirectional noise cancellation addresses both outgoing and incoming call noise, not just the user’s microphone.
• Pro: Meeting recording, minutes, keywords and insights bring call cleanup and meeting follow-up into one product.
• Pro: Local audio and VoiceID processing keeps those data off-device according to the company’s privacy statement.
• Pro: Windows, macOS and Linux support covers the main desktop systems, with minimum requirements stated for each.
• Con: Starter’s included features and limits are undefined, making the free plan difficult to assess before signing up.
• Con: Premium and Enterprise have custom pricing, while Elite is marked coming soon, so paid-plan comparison and availability are uncertain.

Alternatives

For a broader starting point, browse AI Speech Enhancement Software.

• LALAL.AI is a freemium option across desktop, mobile, web and API platforms, with a free tier limited to 10 minutes in the Relaxed Queue, 200 MB per file and previews rather than full downloads. Choose it when wider platform coverage matters more than CrystalSound’s meeting recording and call-focused tools.
• Auphonic offers a free plan with 2 h/month, AI-based audio algorithms and credits that do not stack. It is a better match when monthly audio production quotas are more useful than CrystalSound’s live-call and meeting workflow.
• DPDFNet is free, with Apache-2.0 licensed code and models and no stated commercial pricing or usage limits. Choose it when an open-source option matters more than CrystalSound’s meeting features.
• Riverside Magic Audio has a free plan with a one-off two hours of multi-track recordings, up to 720p video, a watermark and 44.1 kHz audio. It may suit users prioritizing that recording allowance and video capture over CrystalSound’s noise-control and meeting-insight tools.
• DeepFilterNet is free and open source under MIT or Apache-2.0 licenses. Pick it when open-source noise reduction is the priority rather than CrystalSound’s integrated recording and meeting features.
• Denoise is a mobile option for Android and iOS; its free tier lets users import, denoise and hear the full result, while saving or exporting requires Pro. Choose it when phone-based denoising is the need.
• Adobe Enhance Speech is a web option whose free plan is limited to audio, one file at a time, 30 minutes and 500 MB per file, and one hour of enhancement per day, with no strength adjustment. It is more suitable when web-based speech enhancement is preferable to a desktop meeting tool.
• Chatterbox TTS provides open-source models for research and development under the MIT license. Choose it for that use case rather than CrystalSound’s call and recording workflow.

Verdict

Choose CrystalSound if you want desktop call-noise reduction alongside meeting recording, summaries and audio enhancement, especially when local audio processing matters. Look elsewhere if clear plan limits and published prices are essential before you commit, or if you need a focused tool for standalone audio work rather than meetings.
