Animation synchronized on audio cue points

[AMULI]

Hi everybody,

Once upon a time, there was Flash+AS3 and I remember editing an audio files with cue points, then writing code triggering when the player would reach a cue point. A way to easily synchronize an audio-based animation.

I could not find any thread about this problem in this forum (except 10 years old ones, of course). Anyone having an advice (I mean for a HTML5 publishing) ? Thanks in advance.

I am sure you saw this, but just in case copying it here. Adobe Flash Professional CS5 * Use cue points

This feature has been deprecated in Adobe Animate CC

Hi Preran,

Nice to read you again after a couple of years

Ok, cue points are deprecated. But in a HTML5 export, the topic of audio-driven animation remains. Surely many people face that kind of problem : for example, synchronizing animation starting at different cue points in the MP3 of a speech.

What I retain from the obsolete AS3 cue points approach is that it had the merit of guaranteeing points of synchronization between audio and animation.

Playing a significantly long speech audio, didactically illustrated by animation, isn't there a risk of having in some situation a drift between audio player and animation player (but here, my understanding of the inner mechanisms is to poor ), in which case the didactic animation would be totally ruined ?

Or is the nowaday reasoning : bandwidths have grown, don't bother anymore ? But it seems to me that internet users still face a large spectrum of conditions regarding actual bandwidth.

An opinion from someone more experienced than I on that subject is greatly appreciated. Thanks
