Does My Song Really Need Mastering?
If you’ve finished your mix and you’re happy with how it sounds, you might reasonably wonder whether it really needs mastering. Could you simply release the mix as it is and save yourself the extra expense?
Technically, yes. A distributor won’t reject a track simply because it hasn’t been professionally mastered. If your file meets the distributor’s technical requirements, you can release it.
For a song you’re planning to release properly, though, mastering is usually worthwhile. It provides a final independent check, helps the mix translate reliably, establishes an appropriate release level and makes sure the finished files are technically ready for distribution.
Is Mastering Actually Necessary?
There’s no rule stating that every song must be professionally mastered before it can be released. If your finished mix already sounds good, is at a sensible level and has been exported in an appropriate format, you can use it as your release master.
The approved mix is the starting point for mastering. From there, the track can be checked for tonal, dynamic and technical problems, brought to an appropriate final level and prepared in the formats needed for release.
If you handle all of that yourself after finishing the mix, you’re effectively taking care of the mastering stage yourself. The question is whether you’re confident that your monitoring environment and experience allow you to make those final decisions objectively.
Skipping professional mastering doesn’t automatically make a song sound bad. It simply means you’re relying entirely on your own mix and final checks.
What Does Mastering Add to a Finished Mix?
Mastering works on the finished stereo mix as a whole. It isn’t about reopening the production or rebuilding the balance between individual instruments.
The processing might include small adjustments to the overall tonal balance if the track feels slightly too bright, dark, thin or heavy. Peaks may be controlled, the dynamics refined and the final level established in a way that suits the music.
Mastering isn’t simply about making a song as loud as possible. The right level depends on the arrangement, genre and character of the track. A delicate acoustic song and an aggressive punk track shouldn’t necessarily be treated as though they are trying to achieve the same thing.
A separate mastering stage also provides a fresh perspective. By the time you finish mixing, you may have heard the song hundreds of times through the same speakers or headphones. Listening in a different, accurate environment can reveal low-end problems, harshness or other broad imbalances that were difficult to judge while working on the mix.
There is also the quality-control side. Mastering can catch clicks, unwanted distortion, clipped peaks, awkward fades, missing effect tails or problems at the beginning and end of the file. For an EP or album, it can help the tracks feel consistent with one another without forcing them all to be equally loud or sound exactly the same.
Mastering can’t make a track sound identical through every playback system, but it can help the important parts of the mix remain balanced as you move between studio monitors, headphones, car speakers and smaller devices.
Does a Good Mix Still Need Mastering?
A good mix is exactly what you want to send for mastering.
Mastering shouldn’t be seen as evidence that something went wrong during the mix. If the vocal balance feels right, the low end is controlled and the production already sounds the way you intended, the mastering engineer has a strong foundation to work from.
In that situation, the changes may be very small. The track might only need a slight tonal adjustment, careful peak control, a final level decision and a thorough technical check. It may not sound dramatically different when compared with the mix at the same perceived volume.
That is often a good result. Making a large change simply to prove that mastering has taken place would be completely backwards. The aim is to preserve what already works while taking care of the final details.
A mix can also be loud without being fully mastered. Loudness is only one part of the process, and you don’t need to make your mix compete with released records before sending it over. My guide to How Loud Should My Mix Be Before Mastering? explains this in more detail.
Can Mastering Fix a Bad Mix?
Mastering can improve the overall balance of a finished mix, but it doesn’t provide the same control as working with the individual tracks.
If the vocal is buried, the snare sounds wrong, the guitars are too loud or the bass needs completely different processing, those are normally mix-stage problems. Adjusting one instrument inside a stereo file without affecting everything around it is much more limited than opening the mix and changing the relevant channel.
The same applies to arrangement and production problems. Mastering cannot cleanly remove an unnecessary instrument, replace a drum sound or make a chorus feel bigger by adding parts that were never recorded.
Small issues can sometimes be improved during mastering, but it isn’t a substitute for a good mix. If you’re still hearing problems with individual elements, Does My Song Need Mixing or Mastering? explains which service is likely to be more appropriate.
When Might Professional Mastering Not Be Necessary?
I don’t think every audio file that leaves a DAW needs to be professionally mastered.
If the song is a rough work in progress, a private demo or something you’re sending to a collaborator, paying for professional mastering may not make much sense. At that stage, the money may be better spent improving the recording, production or mix.
You may also be comfortable mastering the track yourself if you have the necessary experience, monitoring and tools. Mixing and mastering don’t have to be performed by different people simply to satisfy a rule.
The trade-off is that mastering your own mix removes some of the independent perspective. You’re judging decisions you made yourself, through the same monitoring setup, after becoming extremely familiar with the song. That doesn’t mean you can’t get a good result, but it is worth recognising what a separate mastering engineer provides.
If the mix still has major problems and your budget only allows you to address one stage, I would fix the mix first. Mastering works best as the final stage of a strong production, not as a way of avoiding changes that are still needed earlier in the process.
Is Mastering Worth Paying For?
For a demo or unfinished track, possibly not. For a finished song that you plan to release properly, I would usually say yes.
What you’re paying for isn’t the number of plugins used or how dramatic the difference sounds. You’re paying for judgement, accurate monitoring, experience, fresh ears and a final layer of quality control before the song becomes public.
Some tracks need a noticeable amount of work. Others need very little. Both can benefit from being assessed carefully.
