[gst-devel] Audio stream measurements

[Jeffrey Barish]

I would like to measure the power and other characteristics of an audio 
stream. Ideally, the measurement would take place while listening to the 
stream.  I suppose that the measured value would be written into a file, 
though I wonder about the possibility of writing it into the metadata of the 
audio source.  Is it feasible to implement this functionality as a GStreamer 
element?  Is there already an element that performs a function even remotely 
similar to this that I can use as a model?
