Goodness knows how one sets channel allocation in.

Specify the number of channels in the raw file. I've had a good look at the FLAC documentationīut can't see where or how to encode channel allocations. Properly or is set wrong in the encoder, it may even have been the original software coder who screwed up in the code somewhere.

Into FLAC or rips it to wav, whatever, the channel mapping isn't working So, what I'm thinking is that when someone encodes a multichannel track I can't find any proper documentation on wav metadata, but channel allocation looks to be definitely part of the metadata. With both Flac and wav files - the channel allocation metadata in theįile properties is part of the flac standard. 'Channels : 5: FL FR LFE BL BR' or 'Channels : 5: FL FR FC BL BR' with 6Ĭhannel files stating: Channels : 6: FL FR FC LFE BL BR The file properties, those albums which play correctly state '4: FL FRīL BR' in the file properties. All the multi-trackĪlbums I've got which play rear on the side channels have this set in Which changes the channel layout Side > Rear. It took me agesĪt first to figure out why rear channels were sometimes playing on the Is encoded into the actual track properties (metadata). If I look at the properties of a track in Foobar IĪudio MD5 : C5005F9C6A15A3429B0C007AC401BA2B I'm presently listening to TheĬhicago Quadio set.
