So, Why do you need Mixing and Mastering?
If you are recording an album that you plan to sell, a good mixing and mastering is a must. If you are only recording a demo, you may be able to get away without mastering.
Mixing and Mastering: How It’s Done
Mixing and mastering are the two base components of professional record producing, so it’s important to understand the differences between them.
Mixing—Bringing Multiple Layers Together
Mixing refers to the process of putting multiple layers of audio together to make one final track, or to musically modify an existing track.
Mastering—Optimizing the Overall Sound
Think of mastering as adding sparkle and shine to your music. The term refers to the process of optimizing each track by compressing, equalizing, making stereo enhancements or adjusting the reverberation (echo) effect. 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.
