I'm the opposite. I don't want to use anything except Skype for voice chat. Nothing comes even remotely close in sound quality. If I had the same cpu/crash issues as you I'd be loudly cursing it's name. Luckily I don't and until something can provide better quality I won't be using it.

Right, for voice it's fine. For video it's garbage. I don't quite see how you're the opposite.

“Nothing comes even remotely close in sound quality.” — Mumble?

With Skype I can play games with a group and put the mic in always on mode. No feedback, no audio from speakers, and no keyboard clicks. It's pretty damned amazing to be honest.

Ventrilo and Mumble do have far superior support for massive number of people in a chat room. If you're participating in large MMO raids or Eve Online type festivities the Skype doesn't have the necessary features. For my ~5 player parties Skype blows everything else out of the water and isn't even close.

WebRTC incorporates the SILK audio codec Skype is using, too, except it can go even higher bitrates. WebRTC should sound at least as good as Skype.

Mumble currently uses CELT and Skype currently uses Silk.

The two codecs have been merged/improved into Opus, which is one of the mandatory audio codecs for WebRTC.

But all three are moving to Opus, so very soon it's not going to be the codec itself that will differentiate audio quality between them.

I don't think it's about compression. I think Skype's invested most of their resource into, eg. noise and echo cancellation, reducing environment noise, working around glitchy / clicky sound capture devices, latency, ...

I have about 5 guys that play, and the "chat room" design of Mumble makes a lot more sense for our use case (which could be different from yours). We hop in the server whenever we want, just to hang out, then use it for games when we are all in.

It's also secure, FOSS, cross-platform, and implements a consistent UI. Skype has none of these.

Mumble definitely is the best VoIP solution I've used in terms of sound quality.

Well this is still in beta and already poses threat to Skype.
