From a169aa6364ad857b174457a733ef9487a2d07188 Mon Sep 17 00:00:00 2001 From: upsuper Date: Wed, 31 Oct 2012 04:23:38 +0000 Subject: af_hrtf: clamp output to relieve noises This patch relieves noises from af_hrtf by using av_clip_* instead of casting directly. There are still some noises, which indicates other bugs inside this filter. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@35304 b3059339-0415-0410-9bf9-f77b7e298cf2 --- libaf/af_hrtf.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'libaf/af_hrtf.c') diff --git a/libaf/af_hrtf.c b/libaf/af_hrtf.c index d8ec33e11b..4edf224de9 100644 --- a/libaf/af_hrtf.c +++ b/libaf/af_hrtf.c @@ -26,6 +26,7 @@ #include #include +#include #include "af.h" #include "dsp.h" @@ -541,16 +542,16 @@ static af_data_t* play(struct af_instance_s *af, af_data_t *data) perception.
