What is Music Mastering?

There are thousands of playback systems with all kinds of sound qualities and frequency responses.

From a cheap boom box to an audiophile state-of-the-art home stereo system, not two systems sound the same, specially when you also factor in room acoustics.

That's the reason why once you've finished your work in the Studio, your music mix down needs to go through one final crucial step, Mastering.

Mastering is not mixing, where tracks from a multi-track format, are reduced to a 2 channel stereo mix format (left & right stereo).

Mastering is the process of optimizing all individual frequency levels to meet Industry Standards.

The music sounds punchier, clearer and consistently on point in all systems, meaning wherever medium you play it, the sound quality reaches its maximum delivery potential (MDP).

It's all possible thanks to digital frequency alignment.

Your new master source will be perfectly formatted for manufacturing, so it can make great copies for cds, cassettes and vinyl records.

Your music cds will be RADIO quality ready, or formatted for air wave broadcasting - which is the first thing radio program directors expect to hear from any published material.

You won't even believe how much better your mp3 sounds on the web.


Your new master source (if PMCD was required from us) is also guaranteed to pass the Media FORM CD-5900 test, at any plant in the USA, or We will replace it.

Our philosophy is to never add anything to the mix unless is requested. From our stand point, mastering is a technical process where creativity is placed in solving frequency problems only.

Unless you have basic training or some knowledge on audio engineering, You won't truly grasp some concepts on this subject, so we recommend you to listen to our mastering samples and read our articles on mastering.

Nevertheless, you'll be able to hear the results, which vary depending on the mix and other factors that we will skip for now.

Keep in mind that while some mastering engineers promise "To level the playing field" for you, We promise to tell you the honest truth about what can be done to your project.

In some cases we advise people, to go back and try to do another mix.

Who does that these days? You need to trust someone who knows. That someone is us. If you have the time, please read this entire page, It will broaden your knowledge on the subject.

What is Industry Standard?

Every Cd you buy from a record store or a major record label release, has gone through this finalization process. The benefits are obvious if not dramatic in many cases.

Lack of consistency on the delivery of the sound is one of the most telling signs of an un-mastered piece of music. The sound quality varies significantly from system to system used for playback, and hardly ever sounds the way it did at the Studio.

Signs such as:

- All mixes have mismatched levels.
- A mix lacks of bass and/or high frequencies.
- A mix has excess of bass and/or high frequencies.
- Unclear vocals.
- Incorrect pq indexing (the track ids), etc.

By aligning the music mix frequencies (or optimizing their individual frequency levels), you get a better perception of that mix in any system at any given output level.

The result is a cohesive program that sounds consistent and at its Maximum Delivery Potential (MDP).

At present the Industry Standard sound quality is based on the specifications of the Red Book Convention, which is a sampling rate of 44.1 Khz and a word resolution of 16 bits.

A music production is considered to meet the Industry Standard when its frequencies show adequate alignment of the 3 main densities:

Bass (20-300hz)
Middle Range (1K-8k)
Hi Frequencies (10K-20K)

The music should sound punchy and clear, with all its dynamics intact (an average level of -6db or -10db, and high peak average of -0.5 db maximum, depending on music style).

Output levels should never be too loud as it means that the dynamic range has been compromised (if not already "crunched").

A refined mastering job shows adequate alignment within a 25 to 30 frequency spectrum (our mastering standard).

What is a PMCD?


Pre Mastered Compact Disc.-
The pre-master CD was originally developed jointly by Sonic Solutions and Sony. The PMCD has the advantage of being easily played on an ordinary CD player before glass mastering.

A true PMCD contains the PQ code burst in the leadout area; for this reason relatively few CD recorders are capable of making a true PMCD.

Some CD pressing plants require PMCDs and other disk-at-once CDRs to be accompanied by a hard copy printout of the PQ code information in order to document its authenticity, and thus to prevent confusion with ordinary recorded CDs which may be track-at-once (duped in real time).

What's the Advantage of Mastering to PMCD?

Please, read also What is Industry Standard?
By using a CD-R format for storage (Compact Disc Recordable), is a better medium and more reliable than 1610 & 1630 pre-mastered tape (DDP), or any 4mm/8mm tape format.

The reason is due to magneto-optical technology which has no tape head friction.

This is a storage medium that will last for many years and the last step on your sound production investment.


While the manufacture of compact discs is done to stringent standards, economic pressures can force CD pressing plants to take shortcuts when material is supplied in a non-professional CD format (i.e., track-at-once, instead of disk-at-once CDs).

Some CD pressing plants will accept CDs recorded on ordinary track-at-once CD recorders, but the glass master might be made from an analog transfer (you lost a generation!) from the customer's CD. Other plants will not even accept such CDs.

The problem with track-at-once CDs is that there is a digital gap before each track selection and this interruption in digital data causes excessive errors during the glass mastering.

We have a StageTech EC2 CD Error Checker for analyzing CDs of unknown heritage. That's why all our PMCD's guaranteed to pass the MediaFORM CD-5900

What's Accuracy to MG?

In our book it means that a piece of music has a well balanced frequency spectrum, within the 3 major densities (bass, mid-range & the high end). Their transients are not overshooting, allowing for higher overall output levels without compromising dynamic range.

A frequency curve consistent with a particular style of music should be achieved after frequency alignment. This is what constitutes Maximum Delivery Potential (MDP).

For people without engineering knowledge, our statement on accuracy may not mean much. But relax, because not even some "mastering engineers" understand it, or care about either.

Does Equipment make a difference?

Some so called "mastering engineers" - offer a dirty cheap rate for this service, claiming their motivation is to "help musicians" - when in reality all they do is, help themselves.

How can you tell?
Check their equipment listing.
No equipment listing?
Then once again, beware.

There are only 2 names and 5 digital workstations in total to look for. They are:

-SonicSolutions DAW (24 Bit / 48 Khz or higher)
-ProTools HD (24 Bit/192 khz)
  (That's right folks, 192 Khz sampling rate!)
-ProTools Mix 3 TDM System (24 Bit / 96 Khz)
-ProTools Mix Plus TDM System (24 Bit / 48 Khz)
-ProTools Mix TDM System (24 Bit / 48 Khz)


There are some ProTools versions that don't meet the professional mastering criteria - such as 'ProTools Project 1' 'ProTools LE', and there is even a downloadable ProTools free software version on the web. They are not TDM systems, so be advised of this fact.

Using Apogee filters to do A/D conversion is considered a plus, since neither SonicSolutions nor ProTools can provide a finer digital conversion. DigiDesign argues that their HD- TDM system is as good or better, though.

Other brands most likely utilize an algorithm, acquired or borrowed from reversed engineering, conditional licence, and even illegal patent.

They do not conform to the professional mastering standards found at reputable mastering facilities in the U.S.A.

Brands like: MOTU or Digital Performer, Cubase, Logic, Ensoniq Paris and many others, are fine multi-track recording systems for project studios and even for some major studios. But, not meant for professional mastering.

Some engineers make and/or brag that they do their own gizmos and devices. This is nothing but a gimmick to get your business.

Why would anybody want to add some weird or unknown process to the signal path of a mix that simply needs frequency alignment? Be this analog or digital, it's all non-sense.

So the answer is, Yes!

It does make a difference working with professional tools.
However, if the engineer doing the mastering is not experienced, We guarantee that you will not get a quality mastering job.

Who Needs Mastering?

If you are a major recording artist, most likely, you would not care less. Since, this is totally out of your realm, and it gets all done for you.

You have come to expect only the best treatment to your music (mastering is part of your contract's recoupment cost, right?).

But, what about those who are struggling on their own, trying to market their work, or shopping for a label deal on their own?

What about their dreadful meeting with the radio program director in hopes the station will play their tune?

You guest it, Mastering is probably the least of their thoughts. Usually they are already out of budget when they find out about it, and many will have to skip this step.

We don't know if it's even possible to get radio play on major radio stations these days, maybe College Radio or small local stations.

But if it doesn't sound "Radio Ready", forget it.

To make things worse, it is precisely these recordings coming from these artists and indie producers, that require the most mastering work, since, their mixes come from recording situations where budget is always an issue, and major compromises in sound production quality had to be made.

They hardly ever allocate the necessary budget to do good MIXING, or dedicate enough time.

Songs that came from state-of-the-art studios ($150 to $200 hourly rate) may require much less adjustments than songs recorded on a basement, but still benefit from this process, specially when they reach radio broadcast.

That said, nobody can make a project studio or a bedroom studio mix sound like a million dollar studio mix, but we sure can get close in many cases!

Well, this is what our studio has been doing the last 15 years. Helping this group of artists, present their material with the highest quality possible and at a price they can live with.
