The ACM Wrapper filter enables codecs that use the Audio Compression Manager (ACM) to join a Microsoft® DirectShow® filter graph. Decompression is only to PCM audio. When wrapping a compressor, this filter appears in the audio compressor category and can support additional interfaces. There should never be any need to add it manually to a graph; it is pulled in automatically by the filter graph manager. It is used only for playback or sample rate conversion.
