[linux-audio-dev] 3D fft analysis program

[Andres Cabrera]

Hi all,
I'm wondering if there would be a benefit implementing the Loris 
analysis library (http://www.cerlsoundgroup.org/Loris/) additionally to 
the usual fft techniques for a visual spectrum analyzer. Would there be 
visual differences in both analysis that would be worth while?

Cheers,
Andrés

what I wanted to do. So I'll refocus and try to get it working in 
realtime first. It will probably take longer (because I have no idea 
about jack and the like), but I'll get it started.
