    Hi,
    I have a game with lines of spoken dialogue - each audio clip isn't repeated unless they run the dialog sequence again. Each audio clip is 1 ~3 sentences.
    Is the audio freed properly in webgl, or will it eventually crash ?
    I'm just about to generate 100's of lines of voice generated dialog and be great to know it whether it will work in webgl or not. ie I can just leave a s text instead.

    You can customize your memory management directly with 
    AudioClip.LoadAudioData
    and 
    AudioClip.UnloadAudioData
    if you want to have a tighter grip on how this data is handled.

    Oh cheers, I'm replaceing the aduioClip with a new one each new dialogue sequence. I assume that it would unload the old audio clip?

    Not necessarily. If you have any other objects holding references to that clip it won't be garbage collected, or become eligible to automatic unloading. Using UnloadAudioData() is the best way to explicitly and immediately unload.
