Using sfplay~ to playback multichannel


    Nov 29 2006 | 5:52 pm
    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

      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...
