When you are about to launch an entire album, you should try to extract the most from each track and remove all imperfections, no matter how tiny they are. By the time it reaches the radio, the track needs to sound impeccable, to be level-balanced and have its frequencies tuned. You need to send the songs to the online mastering studio, and just as the name suggests, the entire operation is done over the internet.
You will receive a sample of every track that has been fine-tuned and all your suggestions will be taken into account so that the adequate changes can be implemented immediately. An online mastering studio should offer a turnaround time of only a couple of days for an entire album and in the case of rush tasks, as little as 24 hours. Those who have a bundle of songs that need mastering will surely enjoy discounts.
