SPSTREAMFORMAT
SPSTREAMFORMAT lists the stream formats supported by the Microsoft Speech Platform.
These enumeration elements are all common audio formats ranging from the uncompressed PCM formats to highly compressed formats, and are all supported by the Speech Platform. The Speech Platform downsamples audio that is of greater than 8-bit resolution.
