Hello,
I would just like to ask if someone could shed some light on what the [noiseprof] effect is actually doing.
Is it outputting a 1024 point time-averaged-spectrum? Does it apply windowing/ola when analyzing the audio?
It seems to be a power spectrum but what are the actual values that are actually written into the noiseprofile file? Magnitude in dB? (they seem to be somewhat centered around '0')
I tried looking at the source (noiseprof.c) but I'm not enough into C to really understand the code.
Any help/hints would be greatly appreciated.
Thanks very much.
Marlon
