recording sound

[Phil Davis]

Hi Robert,

I recently had to deal with this as part of moving a Mac-only desktop 
app I maintain for a client from LC 6.x to 7.x. My solution (which works 
nicely) was to create a standalone 'slave' app using LC 6.6.5 whose only 
job is to record sounds. This recorder app is stored in the bundle of 
the main 'master' app and is launched in the background when the master 
app's 'audio editor' window is opened; then is told to quit when that 
window closes. While running, it receives its orders from the main app 
via sockets, and sends a response upon completion of every command. That 
way we know if it's alive and working.

It handles only a few commands:
     startRecording
     stopRecording
     terminate
     enableLogging -- for testing
     disableLogging -- for testing

Of course to simplify things on the 'master app' side I created a 
library containing the commands used by the main app to send recognized 
commands to the slave app.

It's fun to see it work!

Best -
Phil Davis
