TwoWay - echo cancellation not working #169

Closed Panzenbaby closed 4 years ago

Panzenbaby commented 4 years ago

Hey there. All the time I get some annoying echo when doin a two way stream. I checked the documentations which says that I have to use the same R5AudioController for publish ans subscribe stream. So I passed the same instance to both (it's already a singleton but I wanted to be sure). Plus I set the audio bitrate to 8000 which I also had from the documentation. But the AEC is still not working. I checked your sample "TwoWayTest" where AEC seems to not be working too. Could you please have a look on this? Am I missing something or is this a bug?

@Panzenbaby echo cancellation is variable in Android devices because there is no hardware standard -both in their echo cancellation support and also in the placement of the earpiece relative to the microphone. Some devices will work very well, and others not at all. Unfortunately, all we can recommend is that you use headphones if you want to run two-way on Android.
