    Hi all,

    I'd like to be able to change the audio clip that is played on my audio track at runtime. Have seen some examples on the forums but they are all for older versions of the API and it seems to have undergone some fairly signficant changes.

    Has anyone got any example code they could share, or point me in the right direction?

    Cheers

    Is this for timeline? The API hasn't changed all that much.

    If you have the timeline clip, and the playable director that plays the timeline:

    ((AudioPlayableAsset)timelineClip.asset).clip = newAudioClip;
    playableDirector.RebuildGraph();

    Thanks Sean - I actually think my issue is getting hold of the clip in the first place though, not really sure how to grab it.

    The main way to do that is to iterate through the tracks (TimelineAsset.GetOutputTracks()) for the track you want. Giving the track a particular name is probably the most effective way to find it. Then iterate over the clips (TrackAsset.GetClips()).
