Question about the channel descriptors in a flac file create from a SACD ISO 2017-03-09 01:24:38 I created flac files from my SACD ISO files using foobar.I get the following in the "Channels" field when I view the "Properties" of the flac file using foobar:6: FL FR FC LFE BL BRI currently have a 5.1 sound system:Custom HTPCDenon 4308Bowers & Wilkins CM-5 (FL & FR)Bowers & Wilkins CMC (FC)Bowers & Wilkins M-1 (SL & SR)HSU VTF-2 MK4Currently everything plays appropriately.Question is when I add rear surrounds as part of a 7.1 system will the BL & BR channels from the flac file play thru the rear surround speaker and not the M-1 surround speakers??Are the channel descriptors in the flac file used? Is there a way to change BL & BR to SL & SR?? Are BR & BL the same as RR & RL? Is all of this standardized? I did find this info:1 channel: mono2 channels: left, right3 channels: left, right, center4 channels: front left, front right, back left, back right5 channels: front left, front right, front center, back/surround left, back/surround right6 channels: front left, front right, front center, LFE, back/surround left, back/surround right7 channels: front left, front right, front center, LFE, back center, side left, side right8 channels: front left, front right, front center, LFE, back left, back right, side left, side rightin the flac documentation. Seems like it could be difficult to get a HTPC and sound system to cooperate and get the right sound coming out of the correct speaker. On top of that I do not see anything about 4.1 sound. Is there a better file format for multi-channel audio?My sound system is currently in storage so I cannot easily add the extra speakers and run tests with the different audio files.
