Audio loop break ?


I'd like to loop a composition in Millumin but there is an audio break when the composition comes back to the start. So I can't keep a good transition... Is there a solution to loop audio without break ?

Thank you !



  • Hello @achart,

    Could you try with Millumin in 32-bits mode ? (see Preferences)
    In fact, Millumin in 64-bits mode uses an Apple framework called AVFoundation : while it's very efficient to playback video (especially in terms of performances for big videos), it has some minor cons (such as less accuracy to playback loops).
    In 32-bits mode, the old Quicktime framework (now deprecated by Apple) is used : not designed for the future, but in some very special cases, such as yours, it might be better.

  • My Millumin is already in 32 bits to work with my Motu ultralite. Is there an other solution than create a six hours composition ? My installation should play a full day.

    Thanks Philippe!
  • Hello @achart,

    How many minutes is your loop ? Don't you have a crossfade at the end and the beginning of your loop if it's very long ?
    Describe exactly what is your "audio break" ?

    Do you use audio-only files ? Or audio-video files ?
    Be sure to have hit the button "Optimize" to be sure that you're using good codecs (for audio-only files, it should be AIFF or WAV).

    By the way, you can loop your media inside a composition by extending them on the right or on the left : you will see the repetitions.

    It is a 25 minutes installation (played all day long) with 10 x AIFF audio tracks and 2 x HAPQ 1080P video tracks. None audio-video files. I ckecked your "Optimize" section but there is nothing.

    I don't want to crossfade at the end and the beginning of my loop. My audio tracks come from Ableton and it loops perfectly in Ableton. I hoped to hear the same thing in Millumin but there is a little break (a silence and a popping sound) when the playhead goes back to the begining of the composition.



  • Hello @achart,

    Is your loop playing seamlessly in the dashboard ? Put one of your audio loop inside a layer, start it, then move the time around the end (open the "Time panel" on the right of the dashboard).
    For info, Ableton Live uses a very accurate audio processing system, while Millumin uses Quicktime or AVFoundation frameworks that are not as accurate as Live. This may change in the future, but nothing sure at all.
