Sample ACM Drivers (Windows Embedded CE 6.0)
1/6/2010
The following sample ACM drivers are provided:
- The MSFILTER sample provides a simple volume and echo filter. (Both filters are supported within the same driver). This driver supports a custom icon and a custom About dialog box. The ACM provides a default icon and About dialog box for drivers which do not provide their own. Microsoft recommends using the default About dialog box because the driver code is simpler and smaller.
- The GSM610 sample implements the GSM 6.10 voice encoding standard originally developed for digital cellular telephone encoding. It supports a configuration dialog box and automatic configuration code.
- The PCMCONV sample is a format converting filter that can convert between different types of PCM including mono to stereo, 8 bit to 16 bit. It does not support sample rate conversion.
- The ACMWRAP sample is a dll that allows DirectShow to use an ACM codec as if it were a DirectShow filter.
The sample code for ACM drivers is located in %_WINCEROOT%\Public\Common\OAK\drivers\ACM.
