Founded in 2023, we set out to build the most precise, private, and accessible audio analysis tool on the web. Every file stays on your device. Every analysis runs in your browser. No uploads. No tracking. No compromises.
Real-time waveform visualization with sub-sample accuracy for precise audio inspection.
Extract BPM, key, sample rate, bit depth, codec info and more from any audio file.
All processing happens locally in your browser. Your files never touch our servers.
Seamlessly import audio files directly from your Google Drive account.
Analyze FL Studio, Ableton, Logic Pro, Cubase, and REAPER project files.
Web-worker powered analysis delivers results in milliseconds, not seconds.
🤝 Partnered with Google
We are currently in the testing phase! Google requires a certain number of active users to fully verify our Drive integration. We've integrated Google Drive to let you import files seamlessly.
How to help: If you see an "App isn't verified" warning from Google, click "Advanced" and then "Go to SONUS-SPEC (unsafe)" to connect your Drive and help us complete the verification process.
