Which audio decoder "ACM Wrapper" wrap?

[David1105]

Given two graphs, on the same PC, will "ACM Wrapper" use "ffdshow Audio Decoder" or some other audio decoder?

Graph 1: Source Filter -> MPEG-I Splitter -> ACM Wrapper -> Wav Dest -> File Writer
Graph 2: Source Filter -> MPEG-I Splitter -> ffdshow Audio Decoder -> Wav Dest -> File Writer

Thanks!

Good question...

What I would do to help narrow it down...

Options:

1. Play the wave file in winamp (using the OLD in_wave not the new libsndfile one), then look at the compressor reported.

2. Right click the wave file in explorer and go to 'properties'. I have mp3infp installed, which makes a good indication of the codec used, but winXP's built in junk should be able to report the codec as well.

The codec reported is the decoder that is used (I think).
