Mastering the recorded music track is crucial for the saleability of the track. Mastering makes up for any kind of deficiency that might have been present in the recorded track. This is essentially true when there is more than one track present in the album. Mastering fine tunes the tracks and makes it sound professional. This process is absolutely indispensable if the tracks are used for commercial release. Mastering is done to synchronize the tracks in an album. This would mean that when one track finishes, it doesnt lead to another track which is totally different from the first one, in terms of volume and other details. For e.g.: Mastering would ensure that the volume of track 1 is the same as that of track 15 in the album. This is important unless you want to keep changing the volume every time the track changes. When the track is to be released commercially, it will hugely impact its sales if it is not mastered properly. The mastering process maintains the consistency of the tracks in the album. Another important factor that calls for the necessity of mastering is that the final product sounds good in any medium or any space, whether it is played on the speakers on which it was created or on any other music system. The recorded track has to sound good everywhere, not just in the studio. Mastering cannot be performed by any person but it calls for specialized knowledge. Only a trained ear will be able to add value to the composed and recorded track.
