[PATCH] Document a channel mapping for 7 and 8 channel audio.
The FLAC spec hasn't previously documented channel definitions for 7 and 8 channel files, making it difficult to encode 6.1 an 7.1 audio. This makes that definition. The choice is based on popular surround configurations for home theatre and gaming, using the Microsoft WAVEX order, which most tools use internally. --- format.html | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/format.html b/format.html index 59ecd73..3cd8be2 100644 --- a/format.html +++ b/format.html @@ -1248,11 +1248,11 @@ <li>1 channel: mono</li> <li>2 channels: left, right</li> <li>3 channels: left, right, center</li> - <li>4 channels: left, right, back left, back right</li> - <li>5 channels: left, right, center, back/surround left, back/surround right</li> - <li>6 channels: left, right, center, LFE, back/surround left, back/surround right</li> - <li>7 channels: not defined</li> - <li>8 channels: not defined</li> + <li>4 channels: front left, front right, back left, back right</li> + <li>5 channels: front left, front right, front center, back/surround left, back/surround right</li> + <li>6 channels: front left, front right, front center, LFE, back/surround left, back/surround right</li> + <li>7 channels: front left, front right, front center, LFE, back center, side left, side right</li> + <li>8 channels: front left, front right, front center, LFE, back left, back right, side left, side right</li> </ul> </li> <li> -- 1.7.9.6 (Apple Git-31.1) --------------080605080708070007050409--
