Focused tools, clearer answers
Every tool opens directly to the task you came for, with simple controls and a practical explanation of the result. Find a tempo, check a key, edit a clip or build a playlist without navigating a full production suite.
Music tools should feel simple—and honest.
Music Tools Lab is a focused collection for listeners, musicians, DJs, editors, runners and creators who need one useful answer without opening a full production suite.
Your audio stays private
Audio analysis, conversion, MP3 encoding, trimming and vocal reduction run in your browser. Selected audio is not sent to Music Tools Lab. Playlist discovery sends only the artist, genre, mood or song words you enter to the music catalog.
Results you can check
Automatic results can vary with the recording. Music Tools Lab shows when a reading is uncertain, offers practical alternatives such as half-time and double-time, and encourages a quick check by ear when accuracy matters.
Helpful explanations
Each page explains what the result means, how to use it and where the tool has limits. When a format or measurement needs more context, you can follow a reliable technical reference in plain language.
