support pause and resume of audio

[evancohen]

This is a fix for #37. This instructs the child process to hide it's binary output.

Some other idea that I could use your input on:

• API names: could also be mute() and unmute() - or something else entirely?
• Could return cp - might not actually want to expose this, but it is an option
• Verbose logging (could add log messages for these events when verbose logging is on)
• Add state to keep track of pause and add isPaused()
• It's not very DRY, which could be easily fixed

This looks awesome, just a few minor (non-blocking) concerns;

• I wonder if this will work transparently for Windows systems
• I wonder if it works for arec just as it does for sox

The API is 👌 since we are pausing and resuming and not recording silence.

We should also call cp.stdout.pause() and cp.stdout.resume() so we can use the streams internal isPaused() method to track the state of the recording.

On top of that, if you could add these methods to the README that would be 🤘

Looks like you've implemented this in v1 #39! Closing this out.
