What is Music Mastering?

To many people music mastering is a dark art. They don’t really know or understand what is actually going on when an album or track is mastered. This can put the mastering engineer on the back foot with a client so we’re going to take some time to explain what the final stage of the music making process actually is and why it is necessary.
There are a few stages to the audio mastering of a song. Ultimately, mastering is the stage of production that comes after mixing. Generally, mastering works on the track (or album) as a whole. Oftentimes, this is a stereo file but it is common for us to request stems of a track to give us more flexibility in what we are going master. For those who don’t know what “Stems” are, they are groups of instruments. One stem may be the drums all mixed down to a stereo file. The next stem may be all the guitars. Another may be just the lead vocal.
This is a more extreme case of how the song can be broken down into groups. The most common is just the backing track and then the lead vocal. Why would you want this? Well, sometimes when the whole track is compressed or EQ’d we will find that the vocal is effected in a way that we don’t want. In order to correct this we need to get access to just that vocal. A lead vocal stem will help us do this without effecting everything else. This is just one example.

Stages of Audio Mastering

In this first stage of mastering we are working on the track as a whole. This is to enhance it’s audio quality even more than what it was after mixing. It’s not that we are saying your mix is bad, it’s just that so much can be achieved by working on the tracks as a whole. All the while we are constantly listening back to before we started working on the track to make sure that we are moving forward in quality. This is called “A-Bing”. Comparing A (unmastered) to B (the new enhanced master). If we notice that we are not moving the track in a positive direction we undo the steps that were detrimental.
The next stage is more important especially if there are many tracks to be mastered as part of an album. This is the stage where we are trying to make all the songs that are on the same album sound sonically similar. They need to sound like they are part of the same record. Here we take all the enhanced tracks and seek to balance them against each other. For example, one may be too bass heavy against another. Here, we try to match them so that they are sonically congruous. We do this for all the tracks until they are all relatively homogenous throughout the audio spectrum between 20Hz to 20kHz.

Limiting the Master Track

Once all the tracks have been sonically balanced we seek to make them all the same volume. We push the volume of each track up. How much we push the volume depends largely on the genre of music that we are mastering. Our goal at this stage is to manage the volume push, known as limiting, and ensure that all the tracks on the album sound like they are at the same volume. If we don’t do this then when people are listening to the songs in their car they will need to do the volume adjustments themselves. That’s not cool! That’s just annoying for them.

Managing the Transitions on the Album

When the tracks have been enhanced we arrive at the next step. We have them sonically matched and volume balance so we then look to putting them in their album order. We need to make sure that the transitions between the tracks are as the artist and producer would like. Some transitions require a nice gap between them. Other Transitions must be rapid. Sometimes one track even overlaps into the next track. There are times when we might fade in or out of tracks on an album. This is all part of the transitions stage of album mastering.
Once the album transitions have been set we can look to integrate digital information. This is where we use data, such as ISRC codes, to be embedded into the audio files. This information has the unique identifying codes of the song that help you collect royalties and other import parts of the track ID. The title of the tracks and who wrote the song is all included in this digital data. It’s really important and most people don’t even know that this exists! This requires special software for embedding digital data.
That’s it! Your mastered album is now ready to be sent off to the production house. We do this for you by sending them either a physical copy or a DDPI file. The DDPi contains all the information in a digital format and can be easily sent over the internet to the production house. Computer check-sums ensure that all the data has made it to its location.

How do Mastering Services Costs Vary and Why?

Another big mystery to clients is why mastering services cost more if you attend the session. Let us explain. Top music mastering studios are extremely quiet places. The kind of adjustments and changes that we are making to a song are subtle. There is a great deal of sensitivity that is required in listening to make sure that we get the sound right. Even the slightest movement in the mastering suite can be a distraction.
When someone is in the room it is only natural that they will make noise. People move and rustle and breath. All these little, seemingly harmless sounds, add up to be a giant distraction in a mastering studio where everything is under the microscope. As a result, when a client is in the session we find the process takes a lot longer. For this reason, it is unanimous amongst all top music mastering studios that their is a price differential between attended and unattended sessions.
Unlike our recording sessions, mastering services are not charged by the hour. Instead, it is a flat rate per track. The reason for this is that each track requires different work during the enhancement stage. It’s sometimes impossible to know how long it will take. It also gives the mastering engineers the flexibility to really take the time to get a little OCD on their listening and not a the expense of the client. We want to make sure that we’re moving the track forward and not backwards.
