Mmmmm... I'll let you discover the errors (more than one)...
Thanks, I did. :) The indices were actually a typo, but the rest was stupidity by design. :) ...
Now if you want float samples (e.g. to do an FFT) you needfor (...) { int v; v = (16 * sysex_string [2*i] + sysex_string [2*i+1]) ^ 0x80; if (v & 0x80) v -= 256; // Sign extension float_sample [i] = v; }
This is great! I'd never have gotten this bit about the sign extension. Is the 0x80 type size specific or would it be the same for converting to double? ... May I mention your name in the README of the finished tool? First FFT and now this!
