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.

hey,

I'd be very grateful for any help.
thanks very much

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

You can use Emmanuel Jourdan's SoundFilesMerger

You can use Emmanuel Jourdan's SoundFilesMerger 

Use EJ's SoundFilesMerger to create multi-channel audiofiles:

Amadeus opens 4-ch sound files but I doesn't play.

but I'm afraid It can only save stereo wave files.

I guess using 4 times sfplay~ in a sub-patch

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

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 

Centre de Recherches et de Formation Musicales de Wallonie asbl

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...".

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