AYT (AY Turbo) is a new music file format for AY-3-891x and compatible circuits.

AYT files are produced from YM files.
Many tools have been created around this format, some of which can be used directly online (e.g., YM->AYT converter, YM/AYT player, YM sequencer, AYT Jukebox).

Z80A players have been created on several old-school platforms, such as the Amstrad CPC, Amstrad Plus, MSX, ZX SPECTRUM 128, and VG 5000 (with the VG 5210 sound card).
These players have the particularity of occupying little memory space, being very (very) fast, and operating in constant cycles.

Wow! If I understand correctly, the CPC player consumes <= 490 nops in any case and does not require any buffer?

Fixed time player and VG 5000 support, this is a dream :-).

This is very interesting. Wondering if the concept could be extended, or rather trimmed down, to 8253 specific music, which is more basic than AY.

Cool! Great to have more tools like this, I don't know the advantages, is YM files bigger than AYT? But great to have it and examples to test.

I don't know yet if it rulez, but I will assume it does. And I will have to test it with some complex and long ST tunes :)

If 1NOP=4T then why ZX(T-states)=2*CPC(NOPs) ?
It's only approximate, but shouldn't it be more like 4*CPC(NOPs) ?
