From 1aec1f832d2c31a9ed3c3923e4ca7019085cbc96 Mon Sep 17 00:00:00 2001 From: murf Date: Wed, 22 Aug 2007 14:12:24 +0000 Subject: Merged revisions 80166 via svnmerge from https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r80166 | murf | 2007-08-21 10:36:34 -0600 (Tue, 21 Aug 2007) | 1 line This patch solves problem 1 in 8126; it should not slow down the alaw codec, but should prevent signal degradation via multiple trips thru the codec. Fossil estimates the twice thru this codec will prevent fax from working. 4-6 times thru would result hearable, noticeable, voice degradation. ........ git-svn-id: http://svn.digium.com/svn/asterisk/trunk@80241 f38db490-d61c-443f-a65b-d21fe96a405b --- main/alaw.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/main/alaw.c b/main/alaw.c index fbc99b0fe..8baa6a7a3 100644 --- a/main/alaw.c +++ b/main/alaw.c @@ -112,7 +112,7 @@ static inline short int alaw2linear (unsigned char alaw) int seg; alaw ^= AMI_MASK; - i = ((alaw & 0x0F) << 4); + i = ((alaw & 0x0F) << 4) + 8 /* rounding error */; seg = (((int) alaw & 0x70) >> 4); if (seg) i = (i + 0x100) << (seg - 1); -- cgit v1.2.3
