Sound quality is rather scratchy, even when played back from GEMDOS HD
i.e. zero disk overhead. Using 32Mhz CPU instead of default 16Mhz did
not really help.
Interesting. I have Hatari compiled on Oct 18, 2023, 4+64 MB RAM, 32 MHz
*but* TOS 4.04. Can you repeat your test on TOS? For me the sound is pretty
good, except the weird repeat part.
Is it possible that Hatari with just EmuTOS is lacking lacking things
that e.g. initialize Falcon sound matrix, that could happen on real
machine with lots of SW running at startup (e.g. audio ACC / CPX).
For the bad replay quality maybe but for the repeat part (which you seem to
hear as well if I understood correctly) this seems to be a Hatari issue (as
I'm setting registers directly in the interrupt handler).
Strangely, I could get the same bug in Aranym as well. But if I put it in a
real world use case (i.e. the replay buffer and the delay is much smaller),
it worked well. So to me it looks like some timing issue within Hatari
(Aranym).
