If you want to record a mono signal from soundcard channel 3, nama> piano; source 3 You can click on the GUI track input channel button to accomplish that, too. To see the Ecasound chain setup that will be used for recording, you can ask for: nama> chains If you don't want any signal monitoring, use: nama> main_off In that case, 'chains' will show something very simple, such as: -B auto -r -z:mixmode,sum -a:R3 -i:alsa,default -a:R3 -chmove:3,1 -a:R3 -f:s16_le,1,44100,i -o:/home/jroth/nama/untitled/.wav/piano_1.wav You look at it and think, "Of course I could write a script to generate that." And you would be right. After much experience, I would say it is easier to learn the correct Ecasound commands to create this rather than to write a script. However if you'd like to write a script, there are already interfaces for C, C++, Python, elisp and Ruby. And I forget, there is a Tcl/Tk front end for Ecasound, Tkeca, that might meet your needs. It looks pretty, too. Cheers, Joel -- Joel Roth |
