Using sfplay~ to playback multichannel
hey,
I'm making an audio / video patch that will playback audio samples over a 4 channel system. I've only ever used sfplay~ to playback mono / stereo files so far. I have an older version of the patch that plays the audio with 4 channel using 4 seperate sfplay~ objects. However, expanding the patch, I want to have several 4 channel samples playing at once, so I've trying to use 1 sfplay~ object per sample... this leads me to a couple of puzzlers...
-Is it possible to make 1 sfplay~ object playback 4 seperate audio files? (at present they are all mono)
- If not, does anyone know how I can compile the 4 mono samples into a 4 channel sample? - again, all my experience using audio editors has been mono / stereo, so its not a process I'm too familiar with.
I'd be very grateful for any help.
thanks very much
Tom

As far as I know, this is not possible.

Assuming you're on MacOS X, you may try that:

You can use Emmanuel Jourdan's SoundFilesMerger
/J
Use EJ's SoundFilesMerger to create multi-channel audiofiles:
Amadeus opens 4-ch sound files but I doesn't play.
Audacity can open and play it,
but I'm afraid It can only save stereo wave files.
I guess using 4 times sfplay~ in a sub-patch
will be less work.

I didn't mention this before because it isn't free, but I bought
Sample Manager specifically to join and separate multi channel files
- quickly.
It runs without limitation for 15 days, so if you only needed to
merge/split files .... ;-)

As I wrote before, you have to change the preferences in Audacity to be
able to save multi tracks files. BTW, you also have of course to use
"Export As...".

sorry, I didn't see it.
Good to know, anyway.

You didn't mention that you need the newest beta for that, the official
stable version can't do it...
