Audio only

[rwaldron]

@beckmx requested in node-audiovideo, this is still in progress

Really looking forward for the microphone capability, for any voice activated systems.

Worked on this a bit today, I'll ping when I have something worth talking about ;)

[rwaldron]

@ahetawal can you try this:

npm install tessel/tessel-av;

Then you can do this:

var av = require("tessel-av");
var mic = new av.Microphone();

mic.monitor(mic.listen());

setTimeout(() => {
  mic.stop();
}, 5000);

• listen() creates and returns a stream of audio data
• monitor() just pipes it to aplay

I'm unable to find any voice recognition tools that will install on openwrt

@rwaldron I will give it a try tonite. While researching more on this planning to use my Tessel make use of amazon voice service, to send voice commands. Only requirement is :
Audio should be : mono channel, sampled at 16k Hz, and signed 16 bit PCM encoding

And for google speech api, it needs it to be in Flac format,
wondering if these things are possible ?

Well, we'll find out together!

@rwaldron Did try the code above, and it seems to work, and I can hear it repeating, which so cool.
Can you suggest how should we go forward to save this recording as .mp3 and do some transcoding on it ?
