The SndBuf.write() method is documented as "not yet implemented", and test code appears to confirm that it isn't implemented.<br> <br> I want to use ChucK to record snippets during a live performance using MIDI input to control when the recording starts, then use ChucK to play back processed snippets. I *really* don't want to be switching apps (more specifically -- I don't want to be fiddling on a Mac keyboard), so I need Chuck to control it all.<br> <br> So my gambit -- yet to be tested -- is to use ChucK to spawn a command line function to do the recording, such as:<br> <br> def void recordSnippet(string toFilename) {<br> system ("sndrecord " + toFilename);<br> }<br> <br> ... where sndrecord is a command-line recorder (such as /Developer/Examples/CoreAudio/Services/AudioFileTools/afrecord).<br> <br> Questions, always questions:<br> <br> - Given my constrains (real-time recording must be controlled from a MIDI device, not from a Mac keyboard) is this a sensible approach? How have other people managed this?<br> <br> - in the ChucK system() call, is there a way to attach to stdin / stdout of a spawned process? In this particular case, I would like to send it a string to stdin of the spawned process to tell it when to stop recording.<br> <br> - Aside from the afrecord utility in Mac OS /Developer, are there other command-line recording apps that people use and like?<br> <br> Thanks.<br> <br> - Rob<br> <br> _______________________________________________<br> chuck-users mailing list<br> <a href="mailto:chuck-users@lists.cs.princeton.edu" target="_blank">chuck-users@lists.cs.princeton.edu</a><br> <a href="https://lists.cs.princeton.edu/mailman/listinfo/chuck-users" target="_blank">https://lists.cs.princeton.edu/mailman/listinfo/chuck-users</a><br> </blockquote></div><br> _______________________________________________<br>chuck-users mailing list<br><a href="mailto:chuck-users@lists.cs.princeton.edu">chuck-users@lists.cs.princeton.edu</a><br>https://lists.cs.princeton.edu/mailman/listinfo/chuck-users<br></blockquote></div><br></div></div></div></body></html>
