CPU Efficient alternatives to play~ ?


    Nov 24 2006 | 6:00 pm
    hi,
    I'm building a granular synth thingie that uses poly~ to have a dozen or so play~ objects read out a soundfile at different points in time. my issue is that play~ seems to use the same amount of CPU no matter if it outputs 1 or 2 channels of a 2 channel buffer. I would expect that reading only 1 channel would roughly be half as cpu intensive, or not?
    previously, I had used the xplay~ external, mainly because it uses about half the CPU for reading 1 channel compared to play~. But xplay~ isnt UB yet, and this is important in my case.
    So what I'm wondering if there's a playback object or external that does the follwoing:
    - Is Universal Binary - Offers interpolation to avoid aliasing (so no "index~") - Doesnt waste CPU when reading only one channel instead of two
    and
    - Lets one specifiy which of the two channels of a two channel buffer to play ...
    thanks for any advice axel

      does it have to be UB, or is a pure Intel build ok too?

      well, the patch will eventually be a free pluggo, and therefore should be as universally compatible as possible. so intel-only won't do it unfortunately.

      Hi all, since i got my new Macbook today, here are beta builds of three of my externals. http://grrrr.org/ext/beta/max/osx
      I have not thoroughly tested them, feedback is very welcome.
      all the best, Thomas
