Hello Jason,
Thank you for your help. Both of them improved the code. Closing the open file handle is very good, because i saw in the process view many "sh" processes.
But the error is another.
I increase the time of silence to 7 instead of 3.
it seems to be that in this time that session.streamFile is executed (3sec. audio file) , the next instruction session.recordFile is executed, because the first 5 seconds of audio files in the second run are silence.
I have no answer about this control.
for the first my changes works for me, but with a little bit more waiting time.
Daniel
