I don't automatically view dynamic compression as bad and I think it gets an undeservedly bad press usually.I do think it gets used inappropriately at times but we must always consider the type of music, the intended audience and the conditions where it is likely to be played.Some dynamic compression is probably required for any domestic replay. For example, a live band playing in your living room just as they would in a normal live venue would make quite uncomfortable listening. It might be accurate in the strictest sense of the word, but are you actually enjoying the result?Squash it down a little and suddenly it becomes more palatable. The trick is to do this skilfully so as not to kill the music, and that's where I think things have gone adrift in recent years.More generally, having music sound enjoyable on portable systems, or in noisy environments such as cars does require considerable compression. Of course it would be great to have the option to apply this via the hardware, leaving the original intact, that's surely the ideal but sadly not the reality.
