From 7f3a7b5c40b7fda09cbba4bb53e1ced133970930 Mon Sep 17 00:00:00 2001 From: Justin Ruggles Date: Mon, 23 May 2011 17:45:51 +0200 Subject: ac3enc: add channel coupling support Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies. --- libavcodec/ac3dec.h | 5 ----- 1 file changed, 5 deletions(-) (limited to 'libavcodec/ac3dec.h') diff --git a/libavcodec/ac3dec.h b/libavcodec/ac3dec.h index 6cba95b495..f0ab75ae98 100644 --- a/libavcodec/ac3dec.h +++ b/libavcodec/ac3dec.h @@ -58,11 +58,6 @@ #include "fft.h" #include "fmtconvert.h" -/* override ac3.h to include coupling channel */ -#undef AC3_MAX_CHANNELS -#define AC3_MAX_CHANNELS 7 -#define CPL_CH 0 - #define AC3_OUTPUT_LFEON 8 #define SPX_MAX_BANDS 17 -- cgit v1.2.3
