    Can anyone help if this is even possible on the iPhone, and where to start please.

    *connection to the mpeg4 stream (being streamed continuously over http)
    *someway to filter out only the audio
    *some way to access the frequency / volume levels

    Is NSURLConnection a good approach to access the stream?
    Are there any API's for assembling/processing the stream/extracting audio?
    any pointers on how to get started would be much appreciated.

    Have a look through the Core Audio documentation. I'm not sure if it can do #1 and #2, but #3 should be doable.
