matrix2_commentary1_stereo_192.eac3 Jan 6, 2008 This E-AC3 sample uses channel coupling and rematrixing. There are a few places where audible pops and noise can be heard, so a comparison needs to be done with output from a commercial E-AC3 decoder. -Justin Update: Jan 7, 2008 This is a non-issue (but still a good sample to have in the archive) I have gotten a reliable report that the Nero decoder produces identical pops and clicks, which leads to the conclusion that they are from the original source audio.
