Frequently Asked Questions
What formats are supported?
You can download as MP3 (128–320 kbps), WAV (up to 96 kHz sample rate), or MP4 video (up to 1080p). MP3 is best for music, WAV for professional editing, and MP4 for video content.
What is audio analysis?
Audio analysis extracts musical information from your file — BPM (tempo), musical key, chord progressions, loudness levels, and AI-based authenticity detection. All processing happens in your browser using WebAssembly.
Do I need an account?
No account is needed to download files. If you sign up (free), you can save your analysis history and revisit results later.
Is there a file size or duration limit?
YouTube videos of any length are supported for conversion. Audio analysis has a practical limit of about 200 MB for the uploaded file.
Is this service free?
