Good point!
The FFT size and sampling frequency were set to 4k and 44.1kHz
respectively (spatial reso

Perhaps your sampling frequency steps are too large to accurately
capture energy per octave at the low end. Also seems to show up with
your White noise plotted against
Glad you found the error, it would have been an extremely weird problem
if not !

Apologies for not being clear in the OP and for the late response. I had
to find time to do more tests.
The upper half of the screen shot is the waveform and can be ignored.
The lower half is the spectral analysis. Green is the SB3's headphone
output, and red is the phono output. My understandin
