exitOnSilence doesn't work when Audio Gain is set to other than 1 #26

Hi,

I am using your module with Matrix Voice mic array. When I set audio gain to 1 'exitOnSilence' works fine. However, when I set the Audio Gain of the Mic Array to for example 10, 'exitOnSilence' doesn't work anymore.

Best Regards, Raghav

The silence detection algorithm in this library is extremely rudimentary. Some fancier techniques based on other signal processing techniques could be deployed to improve the silence detection. Would you want to try working on it and enhancing this library? I would be happy to receive any pull requests from you on this.
