Any ideas how I could obtain the spectrum of an entire audio file as fast as possible?
By the spectrum of the file, I mean the average value of each bin, over the entire file, for example.
In order to be faster than realtime, I could imagine upsampling would be an option, or using uzi to retrieve the individual signal vectors as fast as possible..hm.. what do you guys think?
Very much appreciating any hints,
all the best
