Arduino Sound Sampler

JamieUK:
Hi everyone,

Long story short: Arduino 8-bit ADC input to Parallel conversion output at up to 28kHz

Having restored my Commodore Amiga, I'm feeling inspired to make some retro sounding tunes... 8-bit mono samples at up to 28kHz... like in the early 90s when I had spots and wanted to be understood!

I don't have much to offer you, but enjoyed your post. I was once very involved with Atari programming, and when the 16 bit Atari-ST came out ( same 68000 CPU as your amiga) , I did quite a bit with when it came to sampling. The ST provided a pretty direct bus to access address and data to/from the CPU, and I remember spending a LOT of money for a 16 bit Burr-Brown A/D (and the cheaper D/A) to see if I could build a CD quality sampler and player. Once done, of course I had a ball learning to do all the cool signal processing tricks (like real time pitch changing, reverb, and other effects). Of course these days a 16 bit 44khz combo a/d and d/a (codec I guess you call them now) is dirt cheap compared to back then.

I think it would be challenging to get decent audio sampling with these ATmega based arduinos without the help of any external hardware. Plus there's not a whole lot of internal memory to hold a sample. But in the "good enough for fun" area, I imagine it will be doable. I'll follow your thread and see how your experimenting pans out.
