First measurement of NOS droop correction

Posted 27th April 2012 at 06:13 AM by abraxalito

Here's a ten discrete tone test waveform played back into my Sony PCM-M10 then FFT'd in Audacity with 512point FFT.

Audacity reports lower freq tones at -18.6dB and the highest (17.3kHz) at -18.9dB - a droop of 0.3dB. This might be in part my passive (LC) reconstruction filter which I have yet to characterize separately. So it appears to work
