Hi all, I would like to introduce VoicePing walkie talkie SDK to add walkie talkie (push to talk) functionality to android app. To learn more please read article below. Many thanks! https://www.indiehackers.com/post/free-push-to-talk-android-sdk-awaits-your-implementation-403653b327

1. What codec is used to compress? 2. Are you handling noise?

1. Opus codec 2. Yes, on the mic input using built-in from Android

You should probably look into noise handling then, what is in android by default gives fairly bad noise reduction result for varied environments

That's valid point, thanks @Joakim Forslund for suggesting that. We will probably be working on that. But it will be complex I guess. Do you know any ready solution for noise handling?

You can look into the recurrent neural network solution made available by xiph

Thanks for the info will check it out 👍
