CaedenV :
It is called a compressor, and it is just a tool. When listening to something with a lot of dialogue you kick it up, when you are doing critical listening for detail, quality, or a author's original intent then you turn it off. Personally I like the creative software suite because it has a great quality compression algorithm for when you need it, and a good EQ to flatten or zero audio for when you are doing critical work, and over digital it is perfect. Personally I would rather have the tools available for my use than not, and most of what I listen to could use a little compression (pop/rock music which is decompressed because it gets so compressed over the radio, Comody and Drama with lots of dialogue, and speeches), and EQ to make it a little richer (though you are right, things like classical/orchestral/acoustic music, and big block-buster movies really should have it turned off, or throw in an expander if anything).
I'm familiar with compressors and thresholds and ratios. I know there is a very real need for it in the studio, especially based on current music trends and the level of compression our generation is accustomed to hearing. However, all the necessary use of these tools is done in the studio. For music, the tracking engineer may or may not use compression during recording; the mixing engineer almost certainly will use compression to keep the tracks consistent in volume and to help them fit together in the mix; and finally, the mastering engineer may exercise broadband or narrowband compression or expansion as he/she sees fit, based on the mastering engineer's skill to know what is enough and what doesn't need more, and also what each song requires after leaving the mixing engineer.
My complaint is that compressors and equalizers should not come pre-loaded on computers and
turned on by default, so unless you uninstall the program, the program runs each time the computer boots, and all changes in the settings minimizing or turning off each feature are reversed back to default upon computer restart.
All of the settings THX TrueStudio Crystalizer offers can be boiled down to three basic results: First, they severely limit dynamic range so the louds are quiet and the quiets are loud. (For information on why this is destructive to the music, watch
this video on Youtube about the Loudness War, or visit
TurnMeUp.org.) Second, they push up the low and the high frequencies creating a "smile EQ", which seems impressive on poor speakers or to people with little understanding of how good music should sound, but in truth it is detrimental to the warmth and tonality of good music on good speakers. And third, TrueStudio provides "surround processing" through two speakers. There are only a few tricks to this non-convincing effect, and they sound "phase-y" and "less real". (The one exception is the now-forgotten mixing technique of QSound, truly giving the illusion of surround sound from only two speakers, with the disclaimer that the speakers need to be placed absolutely perfectly in a room with good dimensions and acoustic treatment, and it only works for one person sitting in exactly one place in the room. Yet it is amazing to hear when these conditions are met.
Amused to Death by Roger Waters was mixed with this technique.)
I'm of the school of thought that if the music is well made, you have no business messing with it. It is very presumptuous to think you know a better EQ curve than the mastering engineer unless you are compensating for problems in your stereo system. And it would be equally presumptuous to apply a compressor to dynamic rock music to get it to sound like the hyper-compressed, squashed result of rock music on the radio, or to apply an expander to an orchestral recording to provide more dynamic range than there naturally should be. I'm also of the school of thought that every piece of the signal chain brings its own problems, and that everything that can be bypassed should be bypassed to maintain the original sound, which is the best sound, as it was intended by the mastering engineer, producer, and original artist.
Alright, I'm off my soapbox. For the record, I wasn't the one that down-voted you, CaedenV. Best wishes.
