Audio

All 16 registers of all three AY chips side by side, with the registers named (tone periods, noise, mixer, volumes, envelope).

Sources lets you mute each chip, the DAC and the beeper independently — a checked box is audible. This is a debugging aid on the output stage only: the Z80 cannot observe it, so muting a chip to work out which one is making a noise does not change the program's behaviour.

Info reports whether TurboSound is enabled, whether the chips are in AY or YM mode, and whether the stereo layout is ABC or ACB.
