Hello folks!
I'm looking for some sound analysis software for Linux. I wish to be able to pass it a PCM wav or an MP3 and have it generate some statistics and preferably some graphs. In particular, I'm looking for amplitude/frequency graphs and harmonic analysers.
Have a look at octave (whose name has nothing to do with sound, by the way)!
This has many signal-analysis capabilities, and can handle sound files in "raw" format. For conversion from other formats, you can use sox, and a command for conversion within an octave session using sox has been written -- see:
Octave is, however, a big package with a huge repertoire of capabilities for computation with vectors, matrices and arrays, and might be overkill (though if you do a lot of that sort of thing it is well worth having by you). It's basically a MatLab clone.
I've never used it for sound analysis, so can't vouch for its performance. Maybe download the manual (big -- nearly 600 pp) and see what you can find.
Hoping this helps, Ted.
I've just emeged sweep, and will play with that. I also intend to check out Audacity.
http://liarliar.sourceforge.net/ is not really what I'm looking for. A google search gives me http://www.cmis.csiro.au/maaate/ (from 2002) but I can't list the contents of that directory.
I had a look at sox, but that doesn't do what I want. I will keep looking, but was hoping that some kind soul would throw me some pointers.
Having the ability to tag sound sample files or tag certain events (ie. tag a specific PCM sample or selection of samples) would certainly be a bonus.
If nothing exists, I could be tempted to have a stab at making a similar program from scratch. Or would consider using libraries/classes in a custom app.
Any thoughts, ideas or flames?
Thanks,
Srdjan
