In MSDN is written:
"The ACM uses stream functions to support data format conversion. Converters in the ACM change the format, but not the data type. For example, a converter module can change 44-kHz, 16-bit data to 44-kHz, 8-bit data. "
Indeed I never succeeded to convert from PCM to MU_LAW for example. So how can I convert from one format to another?
