Overview
This extension provides format support for IMA ADPCM data.
Use of this extension allows the association of IMA ADPCM
in addition to PCM formats for buffer data.
Issues
The caveats and restrictions that relate to all formats supported
via the callback mechanism apply. Namely, certain filters that
rely on having all data present to operate (like the pitch operation)
may result in NOP. This format tag is invalid as an internalFormat
hint to functions that accept them.
The presence of a separate entry point is unneeded and serves no
purpose as the extension tokens, passed to BufferData, suffice to
completely use this extension. Further revisions of this extension
will remove this deprecated entry point.
