Since there are potentially many different drivers that could be handling the final audio device, there is no single point where you can tap into this. If you are developing your own application, then you can simply monitor the current level that you are sending. If you want to monitor the level of other application audio, then you need to develop an audio device driver and direct the other application to send audio to your driver. Otherwise, you would be faced with hooking into the API of every possible audio device driver available for Mac OS X, including proprietary drivers from audio devices which do not use the standard FireWire or USB class drivers.

I know if the SequenceGrabber method of doing this - but was wondering about doing it purely in CoreAudio. I'm aware there is no exposed API method to do it as standard, but wondered what the general approach would be (so that I can go look in that direction). |
