bpmcalc 0.2

bpmcalc is an Amarok script that calculates BPM on song change and update Amarok's database.

This is my first amaroK script which calculate the BPM of the currently playing file. I wrote it after the recent patch which add a BPM field in the playlist. It isn't really useful, but I think it's cool; plus it can make conversations: "Hey! did you know tha this tune is 130BPM!..."

Don't forget to add the BPM column to the playlist (right-click on the column titles->show columns->BPM)

Note the detection is sometimes bad for some music styles or when the bass drum isn't loud enough. However, in those cases the BPM is often a multiple of what has been detected. If you don't agree with what is detected, you can right click the playlist -> bpm -> check manually and press spacebar.

Feel free to modify it or to mail me your
comments/requests/favorite tune!

Requirements:

· Amarok
· Python
· ffmpeg (to convert a music chunk in something readable)
· libSoundTouch (the package is soundstretch on debian)
· permission to write some bytes to /tmp

What's New in This Release:

· fixed so that the script works with filenames containing shell characters such as '
· increased reliabity of "stop"
· do not clobber existing BPM (MP3 only, if eyeD3 is installed)
· do not automatically double measurements that are lower than threshold. It's more likely that the real BPM is 4X measured rate, but we cannot know for sure.
· vastly improve manual BPM, using itjBPM as example for onehanded operation
· . (period): tap
· enter: set BPM
· [ : divide BPM by 2 (by 3 if triple time selected)
· ] : multiply BPM by 2 (by 3 if triple time selected)
· ' (single quote): next song
· / (slash): advance 30 seconds
· 0-9: set rating
· measure counter: click to switch between square and waltz measures
· TODO once http://bugs.kde.org/show_bug.cgi?id=142750 is fixed
· do not clobber BPM on non-MP3 files
· allow comment updating
