Smarter detection of non-speech sample #9

Currently there is only a threshold value in frequency spectrun variance that decides if a sample is noise or speech. Options to look into:

Noise gate: http://en.wikipedia.org/wiki/Noise_gate
Slider for current frequency variance threshold value
Analyse data from microphone and find characteristics of the noise.

Could perhaps use the Web Speech API to detect speech. Might be faster and save time instead of writing separate Javascript code for the purpose. Voice Activity Detection is listed as one of the use cases for this API. https://dvcs.w3.org/hg/speech-api/raw-file/tip/speechapi.html
