stream audio via udp on android
In this post, I tried to play small audio data chunks with AudioTrack to show the feasibility of streaming audio. It's not straightforward enough. So I updated the sample code to actually transfer audio data with udp.
As the image below shows, the application is not too complicated.
The two buttons will each create a new thread to send and recv audio data respectively. And the sender will read audio data from the file /data/1.wav. Then, it sends the data to udp port 2048 on localhost. The receiver reads on 2048 port and feed data received to AudioTrack object.
