- This is how the Amiga's samples are done. Didn't you ever hear horrid 1-bit
- samples on the Apple? Or cheesy 4-bit samples on the C64? The main
- difference is that the Amiga has DMA-driven sample-oriented hardware.
-
- And this is samples as opposed to hardware-level synth: you CAN do
- synthesized sounds on the Amiga, but you have to essentially create a
- sample mathematically and play it. There is nothing equivalant to, say, the
- C64's SID chip in the Amy. (Though there IS a SID emulator, it works by
- creating chunks of sounds and playing 'em.)
-
- And you can do sound manually, too, like you had to do on older machines,
- but there's really no reason to do so most of the time.
-
- For the most part, you CAN look at programs such as Sonix, Future Composer,
- etc, which have synth emulators in them, as programs which output synthetic
- sound. Always remember, though, at the lowest level, they're playing
- samples. (And eating up a good chunk of CPU generating them on the fly...)
