There are technical and creative aspects in mixing. Individual instruments are placed where they belong in the audio spectrum. It is a track by track assessment involving techniques such as equalization, compression and etc. A great mix will move you and make you feel like it was a performance. Mixing usually takes a day or two per song depending on the complexity of a track.
Mastering & authoring is the final process before CD duplication or digital distribution. Mastering ensures that your mix is heard loud and clear on EVERY SINGLE playback source (Radio, boombox, headphones, etc.). Mastering is best left to professionals with years of experience. We work with some of the best mastering engineers in the industry with lots of experience and credits.
