The STe came pretty close with DMA stereo audio playback, though only at 4 sample rates so software resampling and mixing was still required. I did a lot of my own tracking on an 8Mhz 1040STe then later a 16Mhz MegaSTe.

At 16mhz I could do 25Khz playback with full software mixing, or with the 50Khz playback mode the playback routine would "cheat" by just alternating the samples for the two channels per speaker which used less CPU but produced a high frequency squeal that was easily filtered by turning down the treble on your stereo :)

Nice! Yes, I remember the 50Khz mode! For the high frequency noise, there is actually an easy fix (requires a little bit of soldering), if you still have your STe you may be interested: https://www.exxoshost.co.uk/atari/last/STEDACFIX/index.htm
