I?m using csound to write audio files that I then mix with ecasound. I want to know more about how ecaound reads the audio files.
Compiling files with Csound I find that Csound first truncates the audiio file to zero, if it exists, and then writes it anew. |so you may have a problem there. I don't know how much Ecasound will buffer files and complain if contents is exchanged on the fly. But as an experiment, you may try rendering a different filename with Csound, through a script, that after rendering renam,es the file. So some;thing like: csound -o tmp.wav -W file.csd mv tmp.wav ecasound_in.wav While Ecasound is running on another terminal. Otherwise, if you are content, for Ecasound to play the whole file/mix, before reading the new one. You could write a script to loop Ecasound. This will mean a bit of a pause between playbacks, because Ecasound would load anew, but you might use a similar strategy. Compile files with Csound to a temporary name. Each time, before you run Ecasound, check for a temporary name, if it exists, move it and run Ecasound. If no temporary file exists, just play back. If your CPU can run your Csound code in realtime, you might write a clever orchestra/score that would loop your instruments with some GUI or keyboard control and output to JACK, where you could read in the outputs with Ecasound. As long as the Csound outputs stay open all the time, Ecasound could run constantly and you could use the interactive interface or Nama to do your realtime mixing and processing. For the moment, I can't think of another solution with these details, which doesn't mean that there aren't more.
