There are many wars and many wars are worth fighting. There is much evil in this world gagging to be slain. The loudness war is one war not worth participating in. For it will bring no benefit to your record. It is much better to teach the clueless of how to listen. There are several things that make people perceive a song as better sounding over another.

Bands and producers of records are aware of these three facts and they exploit these facts, especially the the first two. They compress and clip to increase loudness and they add unnatural amounts of treble when mastering their records. There is one genre of music that is intelligent enough not to have participated in this loudness and treble war and for very good reason. That genre is the genre of Classical and Orchestral music. As I explain the flaws of the loudness war Classical music is a perfect and easy to comprehend example as to why one should not kill their records with hyper compression and treble boost.

Compact discs have a certain amount of head room this headroom is the span of the quietest noise it can produce to the loudest noise it can produce. This headroom is the space where dynamics in music can be expressed. In Orchestral music you might hear a quiet start by the string section slowly getting louder and then the bras section comes in as the music turns in to a vigorous march but it will still get louder when the orchestra hits the climax with a loud Orchestral hit with timpanis and everything.

In Contrast to this when you listen to modern CDs the music is always hitting the roof of the headroom making the whole CD as loud as the Orchestral hit this makes the CD sound very loud. This is achieved with an array of mastering processors. The Compressor makes quieter parts of the song louder by reducing the Loudness of the louder parts of the song and then increasing the overall volume of the song now the loud parts are as loud as they were before but the quieter parts are now almost as loud as the loudest parts. The next step is to use a limiter which squashes the Loudness peaks down even further and more aggressively than the compressor with an infinite ratio after the make up gain increases the volume of the whole song so the peaks hit the roof again the whole song is now even closer to hitting the roof of the headroom. Now as a final step Comes the Clipping Clipping means that the peaks of the waveform in the music get literally clipped off this is achieved when the songs volume becomes louder than the roof of the headroom allows. This causes the peaks of the songs loudest parts which now go past the roof of the headroom to be chopped off leafing small square wave peaks this causes a degrading of the sound in exchange for added loudness. Such clipping is standard nowadays. A a couple of decades ago sound engineers who even clipped a song by a microscopic amount would get the death penalty for doing so, OK maybe they woulden't  get the death penalty but they would get a good dressing down. The following wave samples show the same price of music after various dynamic processes

When listening to a classical or Orchestral record one notices that the instruments sound very much the way they would sound if you heard them life. If the frequency spectrum of a orchestra was analysed on a RTA analyser one could observe a slow decline in the volume of the treble frequencies as they go higher up. And the orchestra is a good indicator of how much treble should be in a recording if it is to sound natural. Because listeners of music perceive an increased treble range as sounding better many modern CDs have an unnatural amount of treble content.

Everyone wants their music to stand out. And this causes a dilemma called the loudness war. People perceive louder as better everybody else's records are loud and because you want yours to stand out as much as everyone else's you have no choice but to also hyper compress and clip your tracks. Of course the same goes for the treble gain, everyone else's songs are sparkling with treble and if you don't do the same it will sound very dull by comparison. If people are used to listen to high treble levels they get desensitised to it and when they hear a more natural treble level it will sound very dull in relation.

You should know that when your stereos volume is adjusted so that the average SPL (Sound Pressure level) of both the compressed and uncompressed album is the same and you now compare the two, the quieter CD now sounds better. Al you have to do is increase the volume on your stereo to compensate. The uncompressed CD has quiet parts and loud parts. This dynamic range gives the music live and expression. There are no clipped waveforms and no intermodulation distortion. Excessive treble should not be added in the master studio if you like more treble turn up the treble on your stereo.
