Dear all,
I need to convert some *wav files to their spectrum to be able to change some of the frequencies and loudnesses in them and to re-encode these afterwards as *wav files.
Can you recommend any Ruby libraries that can do this (easily) ?
Thank you very much!
Best regards,
Axel

Hi Axel,
never tried it, but ruby/audio (http://hans.fugal.net/src/ruby-audio/\) may provide the functionality you need. the narray library is part of it, which has FFT-processing as a feature.
