Is there a good real-time compressor/limiter for FM broadcast that I can use on a Mac? Preferably one that works as an AudioUnit (AU) plug-in? [more inside]

I recently became an Arbitron ratings person (which I'm not allowed to tell anyone, hence my anonymity). I'm supposed to carry a portable device that they say picks up "sound energy" signals embedded by participating radio and TV stations so they know what I'm listening to, even if the audio is compressed. What the heck is "sound energy"? [more inside]

Hi there, I am doing an honours project on the effects of boat noise on dolphin communication and my supervisor had this idea of using compression to analyse this. He basically suggested that we record dolphin vocalizations in the presence and absence of boat noise, and then compress the files and determine which compresses more (dolphin sounds with the boat noise, or dolphin sounds without the boat noise). His thinking was that less complex sounds should compress less...so he thinks that boat noise will compress less than dolphin vocalizations. Thus, if dolphin vocalizations happen to compress more in the presence of boat noise than they do without the boat noise...this would sort of imply they are "losing information" so to speak. Does this make sense? [more inside]

Is there a free VST- or AudioUnit-compatibile plugin designed to remove or reduce compression artifacts from low-quality audio being re-recorded at a higher bitrate? Or special settings for a specific filter that will do this? I need one for AudioHijack on OS X.
