Hi Timothy, volumedetect will give you statistics about the overall volume of the audio stream like mean value, maxumim value, ... That's interesting for tasks like audio normalization but does not help if you want to have information about volumes at given points. For example, I don't think you could use volumedetect for generating waveform images. Regards, Lars
