I am not a terribly experienced coder but know enough to be able to muddle my way through something if I know it's going to be possible. So my question is if it's possible and is ReaScript (Lua) a good tool for this?
So I want to do a quick FFT on a 320kbps mp3, identify where a steep cutoff is in the spectrum and output a line in an text file the best guess as to its *actual* bitrate.
ie cutoff at 16kHz = 128kbps
It doesn't have to be perfect, just right most of the time. Easy to do on an individual song, however I the intention is to do this to literally hundreds of thousands of songs!
I couldn't find anything out there that does this automatically... any suggestions welcome!
Is it possible with ReaScripts?
Is it better to do with something else?
