hi all,
I’ve almost succeeded with my video recording and freezing the frame and stretching the live input with sndwarp for the total time of the freeze. monitor-opcode works fine. But if turnoff the monitor instr, will it close the file and then turning it on again, it overwrites the file or does it append the new audio to the file?
If it overwrites, how to stop writing audio and after some time appending to the file? Otherwise if I freeze the frame for few seconds, and then wait, say 30 minutes to take the next, there will be blank audio for all that time.

tnx

-m


 

Are you using fout to record the audio? Then once you turn off the
instrument it will finish writing the file. Turning it on again will
cause it to overwrite the file. What I usually do is append the time
and date to the end of the file name. That way I can start and stop
recording as often as I like and not have to worry about overwriting
anything.

Thanks Rory,
I’ve been using monitor-opcode, but it does behave probably like fout. In the manual of monitor, the filename must be a string enclosed in quotes, so how to change the filename? I’ll look at fout, maybe it’ll do filenames differently and can be used in the way I use monitor now.

I usually create my unique string using sprintf.

Csound can join the files too.
