These FLAC files are suitable for testing the channel mapping of a surround-sound system. They use the following channel assignments, taken from the FLAC spec:
- stereo.flac: FL FR
- center.flac: FL FR FC
- quad.flac: FL FR RL RR
- surround50.flac: FL FR FC RL RR
- surround51.flac: FL FR FC LFE RL RR
- surround61.flac: FL FR FC LFE RC SL SR
- surround71.flac: FL FR FC LFE RL RR SL SR
(FL/FR/FC is Front Left/Right/Center, RL/RR/RC is Rear, SL/SR is Side, and LFE is low frequency effects for the subwoofer)
