On real hardware how many audio channels are selected
for example 4 - 8 or else more in this case for sb128 ?
thanks for any advice.

by selecting multiple audio channels, multiple applications working at the same time benefit ?

I worked hard to make multiple applications used at the same time compatible and I noticed that audio plays an important role at least in my case.

here for example e-uae odyssey (aio) and emotion that work together without slowing down:

According to the AHI docs, 10 channels is the recommended value.

Full blast on 128 voices over here with an ESI Julia.
No problem what so ever.

Edit: I think the voice count is a legend of MIDI, 16 channels per MIDI cable in/out. So a multiple of 16 is the way to go..
And of course the AHI recommendations must rely to Amiga 68k.

Anyone with AHI coding knowledge correct me!

AHI's mixing routines are quite primitive and if you increase channels, playback quality decreases even if you aren't playing concurrent sounds.

I would advice to set channels as few as you still find comfortable in your use.

I've noticed that I don't use more than two programs that output audio at once pretty much ever, so I've set my channels to two. This still allows me to play something like video clips or test a game while listening music on the background, but keeping the quality quite good.

This is why AHI has the Music Unit, which overrides anything else playing to keep the quality at max in certain cases. But if you want to let everything (including the Music Unit) to play simultanously, you can forward the Music Unit to other unit, but especially in this case I would really keep amount of the channels low.
