Maybe this issue holds for a lot of rendering profiles, but at least x264 single pass with
AAC audio / 128kBit suffers from very poor audio quality on my machine, which is
32-Bit Debian unstable, latest 0.7.6 packages.
No matter which player used, annoying chirps similar to poor mp3 encoding are audible.
(like in the old days with lots of buggy mp3 encoders)
Streaming out uncomressed PCM audio (unacceptable slow on my machine. why ?) and coding/muxing
(f)AAC audio with identical bitrate in avidemux results in crystal clear sound.
Has anyone experienced similar audio quality issues (MP4/x264/AAC), too ?
