Super nifty! I started a video training course this morning and the speakers voice was super bassy and recorded in a crappy environment - so it was baddddd for me trying to understand this dude. Thought "I need a damn eq right about now" and decided to see what I could find that would fit in the Mac sound stack. eqMac popped up in my searching so I installed. With just a few tweaks with the generic 'free' 3 band eq (bass, mids, treble) - the audio track was not only listenable, it was damn good! Peak limiter being available did help with normalizing the speakers volume and the interface also put the system volume knob right there for me to leverage. Good stuff here!
