Thank you so much for attaching the document! - the information on it is exactly what I was after. Should hopefully finish the article today if all goes well.
Do you know where the doc was sourced from? Don't worry if not, I'll just add Abime on the footnote with your username.
Always been a bit of a sample-head myself, and own lots of Akai samplers still (12-16 bit). So it's nice to know that 14-bit's could be achieved on the Amiga!
It's quite interesting to see how they did roughly the same thing with the ZX Spectrum by modulating the noise generator fast enough that you could playback 4-bit samples.
