Pitch Tempo helps musicians, singers and teachers prepare a short practice recording at a different key or speed. Upload an audio file (MP3, WAV, AAC and more), estimate its key and BPM, and adjust pitch and tempo by typing instructions in a chat. Preview the result and download it as MP3, WAV and more. Separate BPM and key calculator pages help plan a change.
The tool is free, with no price stated. Files can be up to 100 MB and 5 minutes. Guests get 3 new chats per 24 hours, and signed-in users get 5 per hour. Files expire after 24 hours. It is web-based with nothing to install, and English only.
Built to make short rehearsal recordings usable at another key or speed without installing a desktop editor. The focus is a simple path from an existing audio file to a preview and downloadable practice copy.
