Another thing I noticed: When converting Files via batch from FLAC Audio to AAC, mediainfo shows the old bitrates of the FLAC files in the AAC streams - they play fine though.
When dealing with multiple audio streams in a batch and different channel counts (stream 1: Stereo, Stream 2: 5.1, Stream 3: mono, Stream 4: 7.1 ...) - is it possible to set "bitrate per channel" ? Or maybe choose a CFR ? If I set a fixed bitrate, its too much for 2 channels, but not enough for 8 channels
