Audio quality improvement

[zachlevy]

Awesome project. I didn't see any other issues about audio quality, it seems to be quite degraded for me during my testing. Are other people experiencing the same?

Is there any way to improve audio quality?

Would something like an electron app converting to UDP on the client side help? Any other ideas?

Hi,
I agree, it's an awesome project!

There is other issues related to audio quality problems, see #32 and #22

I've experienced the same problem. To be precised, I can perfectly hear someone from mumble-client when I use mumble-web, but when I try to speak from mumble-web, any client (mumble-web, pumble or official mumble-client) receive a really poor sound quality.

I've try to change the chunk, from 4 to 8 in voice.js

this._outbound
        .pipe(chunker(8 * 480)) // <-- here
        .pipe(buffer2Float32Array)
        .pipe(this._client.createVoiceStream())

It's a little bit better, but not satisfying.

Some people says that mumble-server drop some packets, but I don't.
Therefor when I use mumble-client, the mumble server deals with UDP packet that have a size around 44 bytes, +/- 1. When I use mumble-web packets are much more bigger, around 269 bytes and more. Maybe it's this ?

I'm not an expert with JS, but I really like this project and whish that it will works again as expected.

I've this issue also.

Tested the web version on two linux desktops on Chromium 79 - it works perfect.
Tested the web version on Android 10 Chrome 78 - the android user sounds like a robot.
