I know this is not a good forum to ask this, but on the otherhand I know there are a lot of guys on this forum into DSP etc., and they might know the answer to this.
I have an audio signal (say 1V RMS pink noise for the sake of argument) and take say 32768 samples via an ADC. I then perform an FFT on this. I then calculate sqrt(i*i + r*r) of the FFT data to get an "amplitude" at each frequency bucket. How do I interpret these amplitudes? I.e. how do I get the actual amplitude (in volts) of the signal at each frequency? I have searched the web and can't find anything. -- rbl ------------------------------------------------------------------------ rbl's Profile: http://forums.slimdevices.com/member.php?userid=4517 View this thread: http://forums.slimdevices.com/showthread.php?t=34206 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
