Loud echo canceller sound gets even more shrill depending on order #1329

Open JumperLuko opened 2 years ago

JumperLuko commented 2 years ago

EasyEffects Version

6.1.5

What package are you using?

Arch (easyeffects)

Distribution

Manjaro

Describe the bug

I'm being very specific, but it might be good for the refinement of the program as well.

If I put echo canceller below the noise reduction, when the sound is very loud, it generates an even more shrill sound, but it doesn't happen if it's just the first one or if I activate the bypass.

My microphone is mono

Expected Behavior

echo canceller does not generate louder sounds

The echo canceller definitely needs some work. At least for me it has been very unreliable. I have to see if there is another echo canceller library that is easier to use.

Many thanks for easyeffects, @wwmm.

Reading https://github.com/wwmm/easyeffects/discussions/1442#discussioncomment-2407271, I wonder whether it would be possible that easyeffects could use the PipeWire module for echo cancellation.

Many thanks for your work again.

I wonder whether it would be possible that easyeffects could use the PipeWire module for echo cancellation.

I doubt it would be possible to fully integrate it. By "fully" I mean that we should be able to set its parameters as well as measuring its input and output signal level. Just putting it in the pipeline is not enough. As far as I am aware these PipeWire modules were designed to be used by PipeWire. They do not work like general purpose audio plugins.

That being said we could try to see how its code is implemented. Depending on its complexity it might be possible to port it to our filter.
