Yussuf Özkan added the comment: If you read a normal uncompressed AIFF with aifc, the samples are in big-endian order and need to be converted before they can be played on little-endian systems. As all other compression schemes produce big-endian data, so should 'SOWT' encoded AIFF. Therefor

New submission from Toby Thurston: aifc.py fails to open AIFF files containing the compression type "sowt" in the COMM chunk with an "unsupported compression type" error. This compression type is an Apple specific extension that signals that the data is not actually compressed but is stored un
