What does an audio engineer do in mastering music?
So you’re a musician who just recorded your first album. You probably went to a recording studio and played all your parts a couple of times, with the sound engineer who handled all the technical stuff. As far as you know, they must take all the parts they have recorded, burn it on a disk, and then it must be ready to print. Although not entirely wrong, most professional musicians take their mixed recording and send it to someone else for mastering.
What is mastering?
Mastering is the final step in the production of an album where they add the final poet to the recording. This is done by technically improving the clarity of the mixtures. It makes the composition of song sounds more coherent, more together. It also ensures that the mix sounds good on all listening devices.
Well, it’s all good and foolish, but do you have a professional mastering technician when you master a survey?
- Volume Maximization
This is to make sure all audio is at maximum volume so all songs are on the same volume. Ever look at the late night TV, where the volume of ads is a few chores higher than the view you watched? If a professional engineer was involved, they would increase the volume of the TV show to adjust the volume of the ads.
- Ensuring a consistent balance of frequencies
Ensuring that all frequencies are recorded in the survey; bass, mids and treble, so there are no areas where there is no bass / mids / treble.
- Noise Reduction
This is the process of removing audio from an audio signal. When using analogue technology, sound recordings show a type of noise known as a band hover. It relates to the particle size and texture used in the magnetic emulsion sprayed onto the recording media, as well as the relative band speed over the tire heads.
- Coding A
Professional Mastering Laboratory can also take your survey and the UPC (Universal Product Code), ISRC (International Standard Recording Code), CD text (including CD information, eg Album name, Song name and Artist’s name) or other PQ information.
- Error Control
This ensures the integrity of the data stream during CD duplication / replication at any CD manufacturing facility.
Still confused about what a professional engineer engineer does to your CD audio recording when handing it over to them? Do not worry, sound mastering is a very complicated process. I just hope you understand better why professional mastering is an integral part of the entire audio production process. It can make a world of difference!
