imported Wave file out of sync after 1000 frames (25fps)

[Erembodegem]

I'm animating two characters with voice in Animate CC.

I'm using 25fps.

Recorded the voices in Audition CC.

Edited the voices with Premiere CC (25fps)

and exported from premiere CC to a .wav file.

Imported that .wav file onto the timeline in Animate CC (25fps) and set as a stream.

The problem:

After 1000 frames you can start to see that the .wav file is going out of sync (about 2 frames).

After 2000 frames the .wav file is about 4 frames out of sync and so on....

Is there a work around?

I noticed on the forum that this is a somewhat known issue and there is a workaround for 24fps.

But i'm working in 25fps. Any ideas?

It's amusing to find old answers of mine!

I haven't tested lately to see if the issue is still there. If it is, I would expect the sound to be shortened by 2 25th of a second in your case. That would suggest a sample rate of 22195, or 44390 if you're working with 44k sound.

I would first try importing sounds at 16 bit, 44.1 KHz, in the hope that Adobe fixed the problems for that sample Arte.

I have tried both suggestions but still totally no difference.

I have made a test .wav file where a beep of one frame was placed at frame 1 - 100 - 200 - 300 - 400 - 1000 and 2000.

At frame 2000 you can see that the "beep" sits at frame 1996 and stays there. I have made (with audition CC) two new audio files.

1. 16 bit 44.1KHz file

2. 16 bit 44360 Hz file

I both imported them into Animate CC (25 fps - actionscript 3 - audio:stream) and without any change.

You can see both audiostreams where the last beep (that should be at frame 2000) sits at frame 1996.

Could you post a test FLA somewhere?

[Erembodegem]

Yes, sure.

You can find my test FLA file and seperate wavefiles at :

adobe - Google Drive

Thanks for taking a look at it.

I did a lot of tests, with different sample rates and also different frame rates. Couldn't see an easy way to work around the problem, so I submitted a bug report.

If I get a confirmation email with a link to the bug, I'll post it here, so you can add notes. I didn't get an email yet.

Preran​ , can you check at your end if the bug report got through? The title is: "imported sound does not take up correct duration in timeline"

[Erembodegem]

Thank you for the testing you have done and for making the bug report.

I hope there will be a solution soon.

[Preran]

Thanks, Colin. Only the product team has permissions to the form. I am checking with them.

[Preran]

Colin: The team confirmed that they have received your bug request.

[Colin Holgate]

Thanks. It's a shame the form doesn't give you a way to submit a sample file. I gave instructions on how they can make their own file to test on.
