What is mastering?

Mastering is the final stage of the audio production process, and the last opportunity to get your project sounding as good as possible before its release, whether as a digital release, CD, vinyl, broadcast or streaming.

Mastering is a 3 stage process:

Correcting issues

Following a careful review of the audio, any issue in the frequency domain, levels or dynamics that may cause problems in certain playback environments are corrected. Matthew Gray Mastering has invested a lot of time and expense to set up a listening environment which can reveal potential flaws or technical issues in a recording or mix.

Creative enhancement

The second crucial stage of the mastering process is to enhance the creative or ‘musical’ aspect of your project. This involves creative equalisation (EQ), compression and limiting tailored to enhance the musical direction and production style of your project.

Amazing Support

The final stage of mastering involves the assembly of your project into the format you require. This can include track sequencing, fades, gaps between songs to create a flow for your release, as well as PQ codes, ISRC codes and CD-Text which is all completed before the audio is packaged in the format you require.

Vinyl Mastering

At Matthew Gray Mastering we can master your project for streaming and vinyl at the same time.
There are a number of criteria which need to be met in order for a project to be considered ready for vinyl cutting. In order to meet these criteria, some of the things we address during the mastering session include:
Ensure bass is mono up to 100Hz and that its not overly pronounced below 40Hz
Reduce excessive sibilance and high frequency content such as cymbals, hi-hats and shakers
Control the dynamics without excessive levels or distortion
Masters for vinyl are delivered to the client or vinyl cutting plant as 24-bit stereo interleaved wave files. Check out our tips for releasing your project on vinyl.

Stem Mastering

Stem mastering, also known as stem mixing, is like using the sub groups on a live mixing console. Instead of everything being summed to the stereo master output to create a single stereo mix file, you can break the mix down into the specific parts. These parts can then each receive special attention in the mastering session.

Apple digital masters

What does Apple Digital Masters really mean?

In an effort to improve the quality of music digitally distributed through the iTunes music store, Apple have responded with Apple Digital Masters (known until August 2019 as Mastered for iTunes [MFiT]). Apple’s aim is to ensure that the masters produced by approved Apple Digital Masters engineers maintain the highest fidelity right up to the point of the AAC encoding process.
