I keep seeing new terminology on this forum all the time like "crest factor', "head room", and about a zillion words to describe distortion. Let's see we have harmonic distortion, intermodulation distortion, transient distortion, time-delay distortion, DAC distortion, mechanical distortion, glide tone acoustical distortion, phasing distortion, coloration distortion, and "human ear response syndrome distortion". What about humidity, atmospheric pressure, and when the furnace blower turns on?
