Sampling audio levels with OpenAL

Is it possible to sample the audio playback volume in real-time with OpenAL? Specifically, I'm using OpenAL in the iPhone SDK.

You can set the audio playback volume for your samples by setting gain on your sources like this:

alSourcef (sourceID, AL_GAIN, volume)

where volume is a float value of gain between 0.0f and 1.0f.

Sample audio playback volume in real-time? Are you meaning loading a sound on real time upon demand? If that's the case, you can, but there may be a delay for loading the sound.

For OpenAL samples on iPhone, I suggest you this: http://github.com/zoul/Finch
