Audio file de-/encoding question

[Axel Etzold]

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.
