Why is mumble better? (in scientific terms)

[AnRK]

This ones for the sound geeks really, I have a friend that refuses to use mumble and I keep trying to explain to him that the more open frequency response and pretty much complete lack of distortion helps you hear peoples voices more easily over the loud noises of most computer games. So I was just wondering why exactly can you hear mumble better in terms of why the human ear reacts better to this clearer signal, as opposed to the tinny midrange distortion of TS because he seems to think you can hear both just as well. Could try and do the research myself but it'd be a pain in the arse and one of the sound people probably could give an answer, I don't really know specifically what I'm looking for either which doesn't help. In essence I just wanna own his ridiculous argument.

Well... i can contribute and say that your friend is an idiot.

Personally, I think what makes mumble so great isn't the science / coding, behind it, but the sociology behind it.

^ yes guys, but the question is about the tehnical abilities of the program

Well, hasn't it got something to do with "speech", the codec that is used in mumble?
At least, iirc, they say that they had developed it to have easy compression on the frequency ranges of human speech while have a heavier compression on the other frequencies thus allowing for good compression and high quality sound or something like that.

Don't know what TS uses but since it apparently is having worse sound my guess would be that the codec used compresses everything quite rough.
Also, since mumble is newer that TS one reason could be that the compression technology of speech is far better developed/based on a far better developed technique than what TS's codec has been.

Here is one reason...low latency.

Its called speex

Speex: a free codec for free speech

Its the codec for the transmission of speech ... a low latency high quality compression algorithm targeted directly at the human voice.

However all the positional coding and resultant directional audio is internal programming by the mumble dev.

So this means that while the latency between to computers are superfast it all depends of how fast your computer is?? I mean if it's internal programming it's all about how fast the computer processes the data right? So mumble isn't nessecarily the fastest as shown above when there's alot of users in game...?
