There are different sonic areas of a musical part that enhance the music through the various procedures of audio mastering service. The most important among those are:
- Dynamic Range
- Stereo Image
- Total Level
Obviously, there may be mistakes which have to be removed like clicks, pops, sound, etc. And you will find the fade ins and outs.
Decreasing the dynamic range is inevitable in mastering, primarily to attain loudness. However, if it is done step by step, together with pro analog mastering compressors with gentle adjustments, a louder master using minimal dynamic range and depth loss is going to be gained.
Proper tonal balance is among the most significant characteristics of a great sounding master. It differs from person to person, even right now you may hear the huge tonal differences between the CD’s in the market even in the same genre. Obviously, engineers and producers have different tastes.
Tonal balance is achieved when in an engineer’s opinion, hearing fatigue does not happen because of edginess, and the music doesn’t sound dull either. An excellent sounding bass and body, nominal muddiness, higher frequency detail, are all part of a great tonal balance.
A broad stereo picture or image always gives the audio a fuller and larger feel. Widening the stereo image is also something which is done with additional care in mastering.
Creating the stereo picture wider pushes everything from the middle of the mix, thus making more space between the instruments and vocals and providing a sense of depth and distance.
Most people like their songs to sound loud, better said: “As loudly as their favorite CDs.”
Loudness is achieved by compression and at the very end of the mastering chain by a couple of limiters. The loud mix may tie the mastering engineers works in attaining the appropriate loudness because no further compression or limiting and you’ve got a lifeless, depthless, punchless song. So, be aware of the loud mixes.
