Amiga is just a straight 28khz 8bit DAC x4 simple. You don't need to emulate it you don't need to do anything to it.
Read the second link I posted.PC's play at a fixed 44KHz (or higher with a good interface) The Amiga doesn't have a fixed playback rate. It's remarkably complicated to emulate the Amiga's sound accurately.
As for the double pal/productivity mode hack for the 32khz screen modes...well few people could use those modes on their Amiga and games or demos would run slower if used as it massively saps CPU time doesn't it? So dead end really in reality unless you want a blank screen when playing mods.
I used to run 55KHz all the time, no effect on the graphics whatsoever.
[/QUOTE]There is nothing wrong with 8bit DACs though, Bob Yannes who designed the SID chip also designed the Ensoniq Mirage 8bit sampling synthesizer and the stock machine sounds so good the band Inner City used pretty much just that one synth and a drum machine and sequencer to produce their first album in high quality.[/QUOTE]
A lot of early samplers used 8 bit DACs and some used a playback system similar to the Amiga (e.g. Fairlight).
Things have long since moved on though, 24 bit is common now.
The only reason anyone uses 8 bit for audio now is for making things sound retro or effects like bit crushers.
