Mastering: The art of bringing a final mixdown to its finishing stages. In the mastering process all of the power is added to the track. All of the Loudness that you hear on the radio is added during the mastering stage. Without Mastering our tracks would sound weak and incomplete. With this product a client will provide his or her premixed track (one file) to us and we will return to them a Master Recording of their song. We promise to take your track to its most complete form. Whether your track contains vocals, or it is just an instrumental does not matter. Both are compatible with this purchase. However, please note that this product is only compatible with a premixed track. We cannot Master a poorly mixed track to sound great. All necessary mixing must be done beforehand. If you are not sure if your mix is ready for a Master, send it on over to us. We will take a listen and let you know if we can make a great Master out of it. If you are sure that your mix is not up to industry standards, we can do that for you as well. However, to receive a professional Mix & Master you would have to select our other product, "Full Song Mixing & Mastering".
