How to implement an audio codec like libopus in order to save bandwidth

[ludzeller]

Is there any guidance, hook, or template for how to implement an audio codec like libopus in order to save bandwidth? I am using univoice in combination with Unity Relay and the voice transmission quickly creates hundreds of MB per hour per session.

Implementing libopus as external native library for Unity should be straightforward, but I am specifically asking where in the univoice system one would add the compression and decompression. Any thoughts on that?

Hi @ludzeller sorry for the super late reply.

Univoice is getting Opus out of the box in version 4 soon. In the meantime you can check out this fork of UnityOpus I made recently: https://github.com/adrenak/UnityOpus

Here is the scripting reference: https://www.vatsalambastha.com/UnityOpus/

There's some more info here: https://www.reddit.com/r/Unity3D/comments/1hgqq5g/opensource_unityopus_encode_your_audio_data_using/

As far as where you'd put this, you can add it to ChatroomAgent where you encode and decode the audio using opus.
