Hi folks –
Those are very nice modules! Your work is well-beyond my craft level and I’m quite impressed!
I wrote up a description of how I developed, translated and represented the drum instrument waveforms for the Beat Box. The write-up is at my site:
Frankje, the short answer is 22,050Hz, signed 8-bit, mono. I wrote each waveform to a RAW audio file – no header, just samples. Then, I converted the RAW audio file to C language with a program that I wrote (raw2c.c). The page at my site has a link to a ZIP file containing the source code.
It’s very exciting and gratifying to see what you have accomplished! Thank you.
