BeatRoot has moved. It now lives on the Sound Software site

Release 0.5.8 (31.10.2011): Bug fix (-t option wasn't working)

Release 0.5.8-rc1 (10.2.2011): Modifications of BeatRoot by Sebastian Flossmann and Werner Goebl (Thanks!). I haven't checked these yet, but I expect they are all good:

• Display of Number of Beats
• Display Length of Audio file
• Swapped mouse buttons for inserting beat (from middle to right button) and deleting beats (right to middle)
• Magnetic beat line (insert or move a beat line with CTRL and it jumps to the nearest detected onset)
• Selecting part of audio file: sensitive region enlarged to 30 pixel range
• Make panel resizable in both directions (and redraw in x dimension so as to use the entire width of the modern big screens)
• Scroll display in x dimension (+ key shortcuts with the arrow keys)
• Save beats: updates the extension from .wav to .tmf automatically
• Added two sliders to control two parameters of the onset detection. This is helpful when you have audio files with too many or too few onsets detected.

Release 0.5.7 (1.12.2009): Missing source files added.

Release 0.5.6 (9.11.2007): Several requested updates and features.

Release 0.5.3 (21.10.2006): Complete documentation, improved batch file processing, and first release of the 0.5.x source code.

Release 0.5.2 (21.09.2006): Some simple batch file processing and text output for the MIREX 2006 competition.

Release 0.5.1 (11.09.2006): bug fixed where some files failed beat tracking.

Release 0.5.0 (23.08.2006): new version of BeatRoot written entirely in Java. Runs on Linux, MAC and Windows operating systems. New features include:

• Annotation of multiple metrical levels
• Annotation of phrase boundaries
• Improved onset detection
• Improved tempo induction
• Platform independent (Java run-time environment required)
