Sorry for the repeat. This was my first question and I neglected to put [PIC] in the subject line so maybe most readers didn't receive or read it. Anyway, I was surprised at the lack of response from such a knowledgable group, so just to be sure ... here it is again. I need to produce 8 bit LUT's of a single cycle of varying shaped waveforms generated in an audio waveform editor. Programs such as CoolEdit (now Adobe Audition) can generate arbitary waves at 255sps and save as ASCII text data which gives numerical values that then need to be converted one-by-one to hex. This seems like a round-about approach. Does anyone have a better suggestion? I would have thought this need might have been previously addressed by some program that would convert a WAV or raw PCM file to a LUT, where the user specifies the desired number of values. It certainly would be handy. Thanks for any advice on this.
