Audio playback crackles distorted

Post by fmhansen »

Audio, crackles and playback but only when played back in TVP. Same audio file plays back clean and all other applications and if you export the animation/audio from TVP it also place back fine. But while in TVP audio is distorting, even audio files that previously played back fine in the earlier versions of TVP. Using TVP 11.7.1 and OS Ventura 13.3.1

If they are non-proprietary audio files would you be able to upload one or two of the audio files here to see if anyone else gets the same crackling problem with these files ?

You probably already know this, but the first thing to check is if TVPaint's sound preferences sampling rate is set to the same sampling rate as the audio file you are using. If the audio file is 48000Hz then TVPaint should also be set to 48000Hz . (or 44100Hz or whatever it may be ...)

Also, is the "Play All" option enabled in the Proxy settings?

This started happening to me with all my audio in new and old projects a few weeks ago as well. Happened out of the blue, and I have no idea what settings changed or how, as I have been using the same setup for a long time. I have tried to reset/adjust everything I could think of and gone through troubleshooting in other threads involving audio issues, and I have not been able to isolate anything that works.

The only thing I have found is that if I completely erase my config folder as if I have a fresh install it goes back to normal, which is not ideal to redo everything I have customized over time. The same files/audio also work fine if I install the pro demo(i have standard) of the current version of tvpaint, and open them up in there.

This is unfortunate. For next time, here is how to create backups of your custom settings: https://www.tvpaint.com/doc/tvp11/index ... m-settings
Last time I was notified of an audio playback issue, it was caused by the "Play All" option of the proxy settings, which forces TVPaint to play every frame and ignore any lags and might create audible distorsions in the audio track, since it tries to play at the same pace as the animation's playback.

Hi – Still having this same issue. Was never fixed but worked around it (animated without audio) but would love to get this solved. I change TVPaint's sound preferences sampling rate to the same rate as the audio file (44100Hz) and checked and the "Play All" option was disabled by default in the Proxy settings, but still getting the same crackle sound. Maybe I should reinstall 11.7.1, although I should not have to.

Hello fmhansen, we have conducted many tests and setting the Scrub Mode to "Always" and Sampling rate to 48kHz in the Preferences seems to fix the issue:

These settings will be used by default in the next update.

Hi Dean – I changed my preference to these settings, trying both 44 and 48Hz and new and old audio clips but the result is the same – the crackle is still present in playback. It is not present in the actual audio file. The audio files I test were both 44Hz.

Hello fmhansen,

Did you try to reset your config. as kelanhordes did? I have found that it would solve those playback issues in some cases. Don't forget to export your custom settings before doing so.

I'm sorry to read that you're still having the problem with the audio crackle . I have tried to reproduce this problem by using a variety of different .wav and .mp3 files , but I can't reproduce the issue on my end. In your case , do you experience the crackling playback problem with every type of audio file that you use (.wav, .mp3, .m4v, etc.) or only with a specific type of audio file that has the crackling issue ? What do the settings look like on your audio file(s) ? I know you said yours is 44100 Hz , but can you post a screenshot of the other audio parameters ? For example:

Here's a real dumb question - how to paste screenshots into my replies?

Hello fmhansen, you will need to host it on a site such as imgur and then use the [img] tags to embed them into your message.

In the end it needs to look like this: [*img=YOURIMAGESURLDOTCOM][*/img], without the stars, of course.

Or upload the screenshot(s) as an attachment .

Attachments > Add Files. then select option Place Inline for each image you want to embed in your post.

Embed Uploaded Images Attachments.png

(sometimes it embeds the image full size , other times it is a smaller preview , as above, and if you click on the image it expands to full size in a new window)

Attached are screenshots of the 4 audio files I tried using. Each one had a crackle/pop in TVP timeline playback. Although this issue started a while ago not sure what started it. Could have been my upgrade to 11.7.1

FIXED.
I ended up deleting my config file, like kelanhordos suggested BUT first saved all my custom settings, as Dean said, and the crackle is 100% gone. Thank you all!
