P Philip Prins Active Member Licensed User Longtime User Feb 21, 2024 #3 Hello Steve, I have looked at it but could not figure out to send the audio in a byte array. I use AudioRecord and send the AR buffer over UDP to a server. But there is a rattling noise on the receiving end. When i send the same from an Android device the audio is clear. Upvote 0

Hello Steve, I works on the Android side. On the B4J side i use the example from you with threading. With one exception that i use a OPUS library to convert the PCM to OPUS. Upvote 0

stevel05 Expert Licensed User Longtime User Feb 21, 2024 #7 I am not familiar with opus, but if it's adding more processing to the chain it could quite easily cause latency in the signal path. Upvote 0
