jab vamp

jab vamp. Fast music collection BPM (beats per minute) and key detection.

• Any kind of music file format
• Java-based and command-line friendly
• Crawls directories for track files.
• Analysis takes 5 seconds per average track(if we assume as average track an MP3 file with 320 kbit/s and 5 minutes length) on an outdated 2008 PC.
  • Easily crawls 750 tracks within one hour on outdated hardware
• Leverages multicore CPU architectures
• Forked from tfriedel/trackanalyzer.

Prerequisites

• Java 8
• Maven
• ffmpeg (install ffmpeg and have its ffmpeg/ffmpeg.exe executable (and its sibling fprobe,ffprobe.exe) on your $PATH).

Building

Build jab vamp on the command line with Maven:

cd ~/git/

git clone git@github.com:Abdull/jab-vamp.git

cd ~/git/jab-vamp/

mvn clean package

Executing

Once jab vamp has build successfully, you can start it up nd have it analyze music files and directory hierachies:

cd ~/git/jab-vamp/

java -jar target/jab-vamp-0.0.4-SNAPSHOT-jar-with-dependencies.jar "C:\Windows\path\to\someMusicFileThatFFmpegSupports.mp3" /unix/path/to/someMusicFileThatFFmpegSupports.flac $(cygpath --mixed ~/my-music-directory/)

After executing this command, soon, output similar to the following will appear on stdout:

/path/to/someMusicFileThatFFmpegSupports.mp3;2A;132.2
~/my-music-directory/fileB.mp3;7B;136.4
~/my-music-directory/recursive/directory/fileC.flac;10A;133.3

...

Examples

# in Windows environments, jab vamp expects a Windows-style path, enclosed within double quotes or single quotes 
java -jar target/jab-vamp-0.0.4-SNAPSHOT-jar-with-dependencies.jar "C:\Users\Someuser\Music"

# in Windows Cygwin environments, you can use the cygpath command in order to convert Unix-style paths to Windows-style paths.
java -jar target/jab-vamp-0.0.4-SNAPSHOT-jar-with-dependencies.jar $(cygpath --windows /cygdrive/c/Users/Gerrit/Music/)
