Hi list,I tried to use "pd -batch" to do some offline processing, but without success - the patch ran but no audio was computed as far as I can tell.
The same patch worked fine with "pd -noaudio -nogui" (and that patch reaches the limits of my CPU anyway so no great loss) - but it would be nice if the batch mode worked.
See attached for a simple test patch and script, with the output I get here using GNU/Linux/Ubuntu/Lucid/64bit puredata-0.42.5-3 - the batch mode output file is silent, as if no audio was computed.
Has anyone used batch mode successfully? Thanks, Claude -- http://claudiusmaximus.goto10.org
