Hello Thomas,
I didn't know this datasheet, thanks.
I'm not a specialist at all with mathematics for sound, IIr, ...
I wish David could help us here.
He suggests to use an external application (the soundcard of the host
computer or an external appli)
Is it a good way to go (some computers may not have a good soundcard).
What about the Wii emulation for example ?
In other way, having everything into hatari means a full portable
emulator, but more cycles burnt for this.
David, is it possible for you to write something ?
Maybe we could have a full software emulation and a external emulation
(choice would be possible via the parameters).
Any comment ?
Regards,
Laurent
PS : I've returned into DSP emulation for now.
I try to understand why amanita demo (DHS) doesn't render sound.
