I wrote a small utility that converts midi files in LegOs or NQC source
files
and another utility that can convert a "certain" type (i.e. noises) of wav
samples in LegOs.
I think that playing wav files in NQC is very impractical or almost
undoable.
I was successful in converting samples like tada.wav or laser.wav,
but speech was a complete failure
The generated C source code can be used as a basis for white noise
generation (steam engine).
You can find them at www.aga.it/~guy/lego.htm, and I hope you find them
useful.

| Thank you very much! I think your utilities are evry useful! I don't know more about music, so I wan to ask you, if you can convert MIDI to NQC, why didn't you also convert WAV to NQC? Although I can convert WAV to MIDI using anothe utility, then (...) (24 years ago, 30-Mar-01, to lugnet.robotics.rcx)

| Thanks. Now I have converted wav file to mono data sampled at 11025Hz (can be changed) and sample range is 0-255 as below: 144, 150, 154, 156, 160, 159, 154, 149, 143, 134, 128, 120, 110, 103, 97, 93, 91, 93, 96, 102, 110, 120, 127, 138, 149, 156, (...)
