Mastering is adding sparkle and shine to your music. In a very basic sense, when you master your album, you’re making sure that song one doesn’t blow out the speakers while song two is barely audible – in other words, you want the levels of the songs to be similar and you want a general sense of cohesiveness to your recording, It also add the finishing touches to the song to bring it to its highest potential, making as loud as possible without distorting and making the song sound big and strong while sounding wider and clearer to emerge you in its sound. No song should be without mastering!
PLEASE NOTE: Mastering is recommended only for songs that have been properly mixed. Mastering does not alter or change any problems in your mix. Before having your song mastered, you should be 100% satisfied with your mix.
