mp3 playback & omx


    Jan 20 2006 | 10:04 am
    I'm putting together a Max based radio playout system
    for someone, and I have a couple of questions:
    First mp3 playback in Max/MSP; importing mp3's into a
    buffer~ seems really slow on my G4 867 - is this just
    cos it's a fairly slow machine by today's standards ?
    Can anyone comment on the use of mp3 playout systems
    using buffers~ in, say, live situations ? Fast enough
    ?
    The other alternative, using spigot~, I know is broke
    in QT7, but am I right in thinking that under OSX/XP,
    spigot~ can only grab from jit.qt.movie, so even
    if/when it does get fixed, it would only work if I had
    Jitter anyway ?
    With regards the Octimax stuff, what are the licensing
    restrictions on using these objects in standalones -
    I'm guessing that if they're not OK to use in Pluggo's
    then distributing them in standalones is a no-no too,
    but I couldn't find any info about this either in the
    docs or by searching the forum.
    Btw, is it me, or is the (new) forum search engine
    not spectacularly good ? It seems to come up with a
    lot of zeros,
    cheers

      In max/MSP, importing mp3 to a buffer~ is a decompilation process made
      within quicktime : it's damn slow on any computer.
      No solutions, i guess.

      Hi,
      I don't have an answer to your question and this is quite off topic, but I was wondering: where do you get the info that some objects (like optimax) are not legal to distribute as Pluggo standalones ? I searched the site but couldn't find it...

      Hi,
      This is certainly an answer for the pluggo list... but. You'll find
      this information p. 59 in the "PluggoDevGuide35.pdf" documentation.
      HTH,

      They won't instantiate in a pluggo. Might be that they will if the
      pluggo is used in MaxMSP using vst~ (I don't recall), but once you
      try using it in another audio editor, it won't work.
      Best,

      The following patch shows that %~ computes incorrectly N%N and 2*N/N.
      For example: 10%~10 = 10, 10%~20= 10, 10%~30 and higher = 0.
      I use Max/MSP 4.1.
      Has this been patched in earlier releases?

      You should search the archives for explanation of bit resolutions and
      alike.
      Max computes absolutely correct, as in signal land everything is
      floating point. At the border of the range you are close enough to being
      either almost a multiple of ten or just a tiny little bit more. The one
      would show 10. the other 0.
      Floats aren't just as obvious as ints...

      If Max's %~ computation is absolutely correct,
      the left one should be absolutely incorrect:
      max v2;

      Yes, the left one is less precise, you have to make the result
      numberboxes a bit bigger, set the right to 10.31 for example and you'll
      see sometimes a difference in the last digit.
      And there is no absolutation for correctness in floating point... ;-)
      Both solutions are correct in a certain sense, but they don't have the
      same precision.
