Does anyone know where I can find further info on the adpcm4_m16c.lib that was part of the HTSTutorial sample application? Documentation or source would be great, as I am trying to figure out how to create these type of audio files.

Thanks,

Tim

Source code isn't what you need.

You need a PC utility to convert or generate 4 bit mono ADPCM audio from a 16 bit mono PCM source. I think we use an 11khz sampling rate.

It appears you may be able to do this with Audacity using one of the supported WAV formats - but I have not tried it.

You may also want to contact your local Renesas rep to find out more about the ADPCM library, which has a PC conversion utility included in the package:
