Is there a way to introduce 80ms delay/latency to the rear left and rear right channels in a 4.0 setup? I have a computer hooked up to a Samsung TV on the front channels and a stereo hifi on the rear channels. For some reason, audio seems to be delayed by the TV and a very strong echo / "stadium" effect is produced by default. My guess is that the TV artificially delays audio to achieve video/audio synch.
With mplayer I have been able to introduce 80ms delay on the rear channels so that everything sounds just right. For that, I use the following options on video clips that contain >= 4 channels (for example, ac3): -channels 4 -af delay=0:0:80:80 -mixer-channel=pcm and this for stereo files (to get sound in both front and rear): -channels 4 -af channels=4:4:0:0:1:1:0:2:1:3,delay=0:0:80:80 -mixer-channel=pcm I'd like to achieve a similar effect for other apps as well. As it is now, apps like amarok or vice do play on both front and rear even for stereo, but with this terrible echo effect. Is there perhaps a way to setup an .asoundrc and some ladspa plugins to do this? I'm running Linux 2.6.17.13 on Debian Etch with alsa-* packages versioned 1.0.11-5. The audio device is, according to alsamixer, "HDA NVidia Analog Devices AD1988B" ------------------------------------------------------------------------- Using Tomcat but need to do more?
