    Looking at the audio output from the Saturn itself, I see a good 250mVp-p of noise on both channels. It looks like it’s all north of 50kHz.

    There’s no antialiasing filter in the OSSC, so those inaudible frequencies get folded back into the audible band by the sampling process in the ADC.

    I wonder why some Saturns do this and not others?
