Android Question Persistant Microphone Audio storage (saving)

See AudioStreamer: http://www.b4x.com/android/forum/threads/audio-library-v1-5-new-audiostreamer-object.30550/#content
There is an example of saving the data to a wave file.

Create a custom type that holds an array of bytes (audio data) and a long variable (time).
Create a List that holds the recorded data. Collect it in streamer_RecordBuffer and add the audio data and its time to the list.

Each time you add data to the list you should remove all the audio data that was collected more than a minute ago.

Saving the list to a file is simple. You need to go over all the stored data and write it with OutputStream.WriteBytes.
