Thanks,

I may need to listen it on my better speakers and not on my laptop speakers :P

But i made a spectrum image:

It seems quite next to the mp3 - could you give the distorsion more gain?
I just want to compare the syntax - i have now a pitch-shift lib that does a good sound and eats CPU-Time. And the "good" sound is for frequenzies you may not hear...

Regards

I am working on a release-able version now.

What maybe would be some examples:
  • Using CMD-lets / CLI tools for processing: SOX / Rubberband
  • Loading long wave-files to view the wave by resampling them to samplerate 1000Hz
  • Doing a FFT-specrtrum in a full song with 10-1000 hann-windows
  • Storing the hann windows and restore this file to get restored FFT
  • my own ruby class "Frequenzgang" that is able to do some operations (Durty)
  • Ruby Functions freuquenzies Hz to lin and a Ruby FFT window
  • Autodetection for fall-off in FFT and calculationg the db-fall of harmonics.

Some of this elements are quite dirty and need a rework - but they appear to work.

See you, then!
Regards, C.Hackl

So till evening it should be done after the last tests

I tried it but the result is even brighter,as you might expect. I noticed that more distortion gain gave the vocals more "air" so the distortion method may be good for pure vocals. I think that's where I got the idea from - vocal exciters - but it was a long time ago and I'm old.
