Audio at beginning

edited August 9 in MAIN

Hi, guys

I'm using Millumin 4.18.k on macOS Ventura 13.7.6.


When triggering a sound effect cue, I’ve noticed that the very beginning of the audio is always cut off during playback.


How long does it take for a .wav file to be preloaded in Millumin (from decoding to actual playback) when a cue is triggered?

Since I need to use sound effects, I added a 0.1-second margin at the beginning of the .wav file, and that seems to solve the issue.


From my testing, a margin of at least 0.06 seconds seems to be necessary for reliable playback.

But I want to minimize the margin as much as possible.

How many seconds of margin would you recommend adding at the beginning of an audio file?

  • Hello @Sarah,

    A few questions to better understand the situation :

    • What codec are you using ? ProRes-422 ? H264 ? Or if only audio, MP3 ? Wav ?
    • If you use audio-routing, do you have the problem ?
    • Could you try with Millumin V5 : do you have the problem ?

    Best. Philippe

  • Hi, Philippe


    I’m using a WAV file, and even when I set my Mac Studio correctly in the audio routing settings, the issue still happens.

    Of course, I also tested it with Millumin 5, but the same thing occurs.


    Just to be sure, I tried playing the same file in Watchout — and just like in Millumin, the beginning of the audio gets cut off unless I add a 0.06-second padding at the start of the file.


    Interestingly, in QLab, the same file plays fine without any padding — the beginning doesn’t get chopped off at all.


    So I’m wondering: could this be due to the difference in how audio and video programs handle playback?

    (For example, maybe QLab fully loads audio files before playback, whereas video-based software might start loading the file only when the cue begins?)

  • Hello @Sarah,

    Please send us a minimal project (the .millumin + the .wav file) via email. We will open a ticket.

    Thank you. Philippe

  • I've just sent you the email, Philippe.

    Thanks!
