What could cause the frames to get dropped? Maybe it's an A/V sync issue due to the additional filtering?

Does it only happen if the compressor is enabled? What browser? Either way, there's probably not much that can be done to change it. The plugin just inserts a compressor node into the audio processing, all the actual processing is done by the browser. I don't know if there's any way to make it more optimized.

Hi!

I am using Firefox 103.0.2 (64-bit) on Kubuntu.

Thanks for letting me know how it works. I was checking the code but not really in-depth yet. Now it also makes much more sense.

The only thing you could do is to REALLY undo the injection when you disable the plugin. Because when I do that, it still drops frames until I reload the page. Is that possible?

I will try to open a bug report for this at Mozilla. I hope they don't redirect me back to you...

Best regards,
Kyo
