songanalysis
What the heck is this? What’s this useful for?
This program analyzes a song in WAV, Ogg Vorbis or MP3 format and produces an output consisting of the volume differential, the relative strength in each frequency band, and the tempo.
This is useful if you want to build something that lets you find out whether you have duplicate files, or if you need to find out the tempo of your songs, or if you need to find similar songs according to how they sound.
How does it work?
Believe me, I still do not know exactly, but it works!
What do I need to use this program?
A variety of things. You need to have:
- a package called gsl - the GNU Scientific Library
- For MP3: the mpg321 program
- For Ogg Vorbis: the ogg321 program and its vorbis libraries
Of those, all are available on the Internet, as source packages and as precompiled RPM packages.
