Running SNDTEST2.NES with the following configuration:
(that is, full volume, timer = 255). So pulse = fCPU/(16*(t+1)) suggests that should have frequency ~440Hz.
Attaching audacity to the loopback device for my speakers and playing that gets me:
Put through plot spectrum gives:
Running exactly the same process on Mesen gives the waveform:
and spectrum
