+/7/2014:
+Today we were working on the sound streaming. We will make a separate setup (realtime streaming) from the initial audio setup (scientific experiment setup), so that we don't overload the former one.
+The idea is to put an additional soundcard (Focusrite) of 8 channels. With this setup (2 soundcards) we can add some microphones but we can also recuperate some audio streams from the other soundcard for streaming in realtime.
+We add 2 electret microphones and I install them left and right in the hive entry, on the basic level. Vincent adds splitters to the 4 existing electrets, and also to 2 existing piezo's. For the new electrets we add 2 pre-amps in the rooftop cover.
+In total we will stream 8 channels, but I can modify at any time by disconnecting the channels that I don't want to stream.
+The stream out is a USB connection. We will connect this to the Raspberry from which we will send the stream. As this new Raspberry will be located outside, on the hive, we need a long USB cable to connect the Focusrite output, and this without loss. Therefore we found an 'active' USB cable which should transmit all data without any loss.
