What is Audio Mastering?
Mastering is simply quality control. Back in the day, this profession was executed by "transfer operators" where music from a tape reel was passed through a transfer console, and sonic aspects of the music were adjusted so that the final product could be sold and distributed through radio.
This principle still holds up to this day despite the evolution in technology. We are making sure that what you did can be reproduced in all scenarios possible: loudspeakers, headphones, hi-end HIFI systems, streaming, etc.
Your work (final mix) is probably in great shape and all that it needs is some quality control so that your music becomes more audible so that people can listen to it and enjoy it without any discomfort. This is the process where Mixing Meets Mastering!
The Importance of Professional Mastering
If you're new to music production, mastering is the last step in the audio production chain. It involves critical listening to diagnose the technical quality of the music, then critical decisions are made like tone and level adjustments to optimize the sound for better playback and distribution.
One of the biggest benefits of hiring a mastering engineer is getting a fresh, neutral set of ears. You might have been working on your production for a long time, which means your ears and brain are totally familiar with it. A mastering engineer can provide insights and feedback about details that may pass you by, ensuring consistency and quality control.
