Special application: Analysis and Inversion

Maybe someone has a clue: I'd like to FFT-analyse a wave file in order to get the magnitude values of the various frequency bands (possibly with accumulated values: giving the overall frequency imprint of the whole file in one averaged curve). In a second step I would like to A: filter a separate sound file with that very same magnitude pattern, or B: filter the separate sound file with the same magnitude pattern, but inverted.

Would Spektral Delay or rather Vokator be the app to do it?

Does Spektral Delay have a plugin interface or something similar where I can define frequency settings at al by inputting a numerical text file or the like?

Any help is much appreciated!

 

Judging by the low post count my guess would be 'no'. It sounds to me like the thing you are trying to do might be more suited to an engineering tool such as Matlab. Matlab is powerful and cheap if your a student, powerful and expensive if your not a student. I love it. Check out www.mathworks.com for more info.

Thanks for letting me know. I'm about to get Samplitude 8, and found that it comes with an offline-FFT-filter that does just what I need. Will look at Matlab, though.

 

Cool, I may look into Samplitude 8 myself, it sounds pretty interesting,

All the best,
David

 

I'm pretty sure there's nothing the matlab-filters won't do, but they're probably also costly to match.

Yes, check out Samplitude - the audio tools that come with it (like the phase linear FFT filters and the convolution reverb) sound really great. I'm not so sure about the MIDI bit, but I'll see. There's a free and fully functioning demo at their website www.samplitude.de.

Check out Plogue Bidule.
A lot of FFT modules in there.
