[Gambas-user] Reading the microphone? Playing audio from a socket? VOIP.

[Titan Rain]

Anyone know of any examples or cases of accessing the soundcard/microphone in gambas? I'm looking to capture output from microphone (and level if possible) and write it to a socket, and read the socket that will have audio data and play it. Push-to-talk style VOIP.

For writing to the socket I've already been looking into shelling something like arecord or pacat. I find arecord uses way too much CPU, but it does seem to be returning the mic data with levels in realtime. Still the CPU is at like 80% when it runs. I can't shoot the cpu that high each time the user pushes the talk button.

Pacat does not seem to return realtime data from the device. It records from a device into a file only, as far as I can tell.

Neither are a preferred solution as end user would need these additional packages and their deps.

Any info on any of the different parts
1) reading microphone data/levels
2) writing microphone/audio data to a socket
3) reading a socket with audio data and playing it
is great, even if it's maybe just kind of semi related it may help achieve the end goal. Thanks for your time!
