Adding audio effects

[bluedirk]

I was wondering whether anyone has seen audio effect plugins for mumble? (Reverb, chorus, delay, etc.)

It's in my need/want basket. lol.

No.

Kissaki,

Is there any way to method for using 3rd party plugins for that purpose, since it isn't native to mumble and it's original purpose?

What we currently call “plugin” in Mumble is only for Positional Audio.

We are aware that making Mumble more extensible would be great, and providing such a plug-in system is a long-term goal for us.

Unfortunately, we do not have anything like it in place right now, and our time is limited.

If you want to go ahead though, we are very open to suggestions, discussions, and patches/code. You could just extend Mumble itself in your own code-base, or tackle the plugin-system for Mumble.

What I need is to grab the (stereo) stream received from other clients, apply audio post-effects to it and then finally send it to the user.

From what you answered, I might assume Mumble hasn't been prepared for that kind of interaction. If there is, where can I hook into?

Thanks so very much.

This is correct, as far as I'm aware. We have no general purpose plugins or hooks for the audio side of things - the best you can do at the moment is something like Virtual Audio Cable on Windows: a pseudo device that Mumble outputs to, which alters the signal, and then sends it to the real output device.

Also note that Mumble's audio stream is never stereo, as far as I know.

Following up on this topic: There is now a fully-fledged plugin system coming with 1.4.0. See https://github.com/mumble-voip/mumble/pull/3743 for its implementation and its status.
