• BPM Detect - automatic BPM detection tool - LinuxLinks

  It uses SoundTouch’s BPM library for detecting BPMs, ffmpeg for reading and writing BPMs to tags and Qt for the GUI. It supports detection with any audio format that ffmpeg can read. However, for files containing multiple audio tracks, only the first seen will be used for detection.

  Some formats cannot save tags. The application will not warn you about these. M4A (AAC, 3GP, etc) store tags in the tmpo atom which is limited to integers but this will not be seen as saved on restart because ffmpeg does not parse the tmpo atom when reading the file.

  This is free and open source software.
