Even better, try upgrading to the latest stable ecasound (2.2.0, 2.0 is nearly two years old). Then use native ALSA access... for example (using your original example): ecasound -c -r -b:1024 \ -a:1,3 -i:alsa,default \ -a:2 -i:Metronome.wav -ea:300 \ -a:1,2 -o:alsa,default \ -a:3 -o:Guitar-Vocal.wav Now if you still get a glitch during recording, 2.2.0 will print a warning or error msg about it. From this info it is usually possible to determine whether the performance problems are caused by disk i/o or task scheduling. PS Sorry for not answering sooner to your query. I did read your original mail on ecasound-list, but just didn't have time to answer it... :( -- http://www.eca.cx Audio software for Linux!
