[Audio] Microphone Capture - Allow setting smaller chunk size for low latency

[virajkarandikar]

• [x] I have searched to see if a similar issue already exists.

By default the streaming mic capture uses buffer/chunk size of 1 second. This adds a long latency in real time applications. Can the chunk size be made configurable/smaller?

Is your feature request related to a problem? Please describe.
Large buffer increases audio latency and makes application sluggish to use.
