In the last few weeks I started to notice that some of my songs were sounding terrible playing on my laptop. I thought it was because they were low bitrate or something, and some were, but other were bought from iTunes so shouldn't sound like streams. Turns out the "sound enhancer" option in iTunes was turned up all the way. Anyway, my question is what is the default setting for this? It is even on at all. I think I might have turned it on on a whim but I now realise everything sounded fine before I had touched it but I can't remember what it was set to.
