<H3>SUMMARY</H3></FONT><FONT FACE="Verdana" SIZE=2><P>
Each of the three samples Msfilter, Msgsm610 and Imaadpcm illustrates an implementation of an Audio Compression Manager
(ACM) software codec.
This sample in particular
implements the ETSI GSM 06.10 standard for voice compression. This compression is useful for audio having voice content.
The sample works on both x86 and Alpha platforms. It is 64-bit compliant, but requires the addition of 64-bit
headers before compilation. It builds properly with Microsoft® Visual C® 6.0.
The sample does not support Plug and Play, Power Management, or On Now. These features are not applicable to ACM
software codecs.
