[chuck-users] Fwd: Automated batch conversion of ck files to WAV

[Dealga McArdle]

maybe: call the file with something like rec.ck but with arguments.
(my rec.ck is called wav_writer_wgain.ck)

> chuck your_main_track.ck wav_writer_wgain.ck:duration:wav_name:gain

https://github.com/zeffii/ChucK/blob/master/ck_files/wav_writer_wgain.ck
where:
wav_name would be the desired output name
duration is seconds,
gain is 0.0 to 1.0
