Formats wrapped inside a RIFF container (for example GSM 6.10, ADPCM, CCITT, etc. ) are supported if the specific ACM (Audio Compression Manager) codec is installed inside the system.


Multi-channel WAV, AIFF, OGG Vorbis, OPUS and WMA formats are supported natively when the ConvertFileDestResamplingSet method has been invoked with the nChannels parameter set to  a number higher than 2 while in other cases will be converted to stereo during the conversion procedure.
