The art of audio mastering is just that: an art. Whether the final delivery format is CD, vinyl, digital download, streaming or Dolby Atmos, mastering is the last technical and artistic step in the production process.

While it’s true that great equipment is very important in realizing a project’s full potential, it’s only useful in the hands of an experienced engineer, equipped with the critical listening skills to help create a master that realizes your true creative vision.

We bring professional, unbiased ears, and a fresh, invaluable third-party perspective to each and every project. Our goal is to help our clients end up with the best sounding projects possible, giving your upcoming release a far better chance at being successful.

We encourage clients to attend sessions when they can; that’s one reason we built such a comfortable room here in Westchester, NY. Hearing your masters play on our full-range reference monitors in our calibrated listening environment may be the best listening experience you’ll have.

Our staff is dedicated to helping all clients, big and small, and will treat them with equal care, focus, and relentless commitment to the craft. We look forward to working together on your upcoming release.

Analog

We have a beautiful ATR-102 tape machine that sounds fantastic. It is equipped with quarter inch and half inch heads. I love working from tape. If it’s in your recording or mixing budget (especially rock records with live drums and guitars) you should consider it. People ask if I have a preference recording at 15 ips or 30 ips and the answer is I’ve heard great records recorded at both speeds. Please label your reels and supply a set of test tones for tape machine alignment.

Digital

There are many variables to working digitally. These are suggestions, not necessarily rules, that can be very helpful in getting the best transfer of your mixes. Most audio workstations now are 24 or 32 bit. If you can work at 24 or 32 bit I suggest to do so. The noise floor is noticeably better than 16 bit. This has a cumulative effect when recording and mixing.

Leave headroom. It’s not necessary to make your mixes loud and can often do damage to your music by adding distortion and smearing the stereo image. It’s best not to do any extra processing prior to the mastering eq just so it’s louder. If you want to use aggressive limiting on your mix I suggest making 2 passes, one with and one without so we have a choice and compare in the studio environment then make the best choice for the particular song.

Apple Masters

JLM is an approved “Apple Masters” studio. What this means is that Apple has provided us with the proper systems to ensure we are creating files to their standards. The “Apple Masters” program allows you to submit files at 24-bit resolution and sample rates as high as 96k. (The typical quality is 16-bit, 44.1k). Please check with your digital distributor to find out if you’re eligible. We can provide you with high resolution masters, either way, in case you would like them for other sites.

Vinyl

Vinyl is still a viable way to get your project out to the world. In fact, it has become much more popular in recent years, especially in the alternative and rock world. With the increase in digital downloads and decrease in CD sales, vinyl is one of the best ways for many artists to actually sell their product.

Listening to a vinyl record is a unique experience, and there are some who insist it’s still the best way to listen to music. Similarly, cutting a record is a unique process, and is much different from mastering for a digital medium. Variables such as side length, volume, bass, sibilance, phase between left and right channels need to be taken into account. Knowing how to manipulate a cutting lathe and take all these things into account is critical to a great sounding record.

There are a few ways to approach vinyl. If the project is already mastered, the high resolution digital files can be used to create lacquers. Specific adjustments to optimize the audio for the vinyl medium will need to be applied. This is the most commonly used method and we are happy to recommend a cutting engineer to you. After lacquers are created, they will go on to plating and pressing. (Some clients opt to incur the cost of getting a separate digital mastering pass done specifically for vinyl). There is also Direct Metal Mastering which skips the lacquer step, but we don’t usually recommend that for sonic reasons. For the analog purist, there is the option of cutting directly from tape.

Sample Rates

We can work from basically any sampling rate you’re comfortable working with, but they do not all sound the same. I like 44.1k and 88.2k when trying to get that vintage analog sound. 96k also sounds great; it has a more extended high end. It’s especially good if it’s going to be left there and not converted down to 44.1. I think 88.2 sounds better when converted to 44.1 than 96 does. Great sounding projects have been created on all these formats. Please do not convert your project from whatever sample rate you are working at just to send a higher sample rate to us. It is going to go through my analog chain.

Metadata

One part of metadata is the ISRC (International Standard Recording Code), which is a unique code for each individual track. Most record labels are set up for these and supply them. Digital distributors can also assign these for you. They are helpful in tracking radio play, licensing for films/commercials and are helpful in royalty collections. If you want to apply for these go to: https://usisrc.org.

We can also create a DDP master with CD text that will show up on most CD players. The metadata for your digital releases will be entered by you or your team during the distribution phase.

What is Dolby Atmos Music?

It’s a multichannel platform giving you an “immersive” listening experience, putting you inside the song so to speak. Although there have been several surround sound platforms over the years, Dolby Atmos allows the listener to hear and enjoy and create immersive content using headphones when connected to an iPhone or other approved device. Currently Apple Music, Tidal, and Amazon Music include Dolby Atmos Music tracks as part of their subscriptions. There is good reason to believe that Spotify will soon.

Will it become a new audio standard or just a passing fad?

We don’t know yet. There are plenty of reasons to believe it’s going to be around for a long time. For one, it’s been around longer than most of us think. Many movie theaters have Dolby Atmos playback. Dolby Atmos is already available on many of the TV shows we watch now. Apple, Netflix, and Prime Video all provide Dolby Atmos content. This tells us they are committed to it and have the infrastructure and resources to help it succeed.

Maybe the most important reason it is likely to succeed is that there is no real extra cost to the consumer. Yes, Atmos is a multi-speaker format, but all you need to experience it is headphones. This, in my opinion, is the most important factor in Atmos succeeding in the music delivery world. The vast majority of fans won’t be experiencing their favorite surround sound music in an Atmos-equipped room, at least not in the foreseeable future. They will use their current headphones. If people listen to their favorite music in Atmos on their headphones and think, “Wow! This is so much better!” then the demand will be there.

Delivering an Atmos Master File

As you may have figured, the master files required for delivering an Atmos mix is more complex than a typical stereo file. There are several Dolby Atmos Master Files and the ADM BWF.wav is the industry standard that includes the Bed Audio, Panning, and Object information. We can create and deliver all necessary files for you.

Loudness

One very different part of the Requirement for Dolby Atmos is all deliverables must achieve an integrated Dolby Atmos loudness that does not exceed -18 LKFS with a True Peak measurement that does not exceed -1 dBTP. That’s a lot lower than most music created since the advent of the CD! So you can no longer just put a digital limiter on and make it as loud as you want. You gotta work for it : )

These are just the main reasons that the mastering process is more important than ever to make sure your masters are delivered properly and sound as good as they can.

What We Need From You

Please note we will need the original stereo master of whatever you are having mastered for Dolby Atmos. So, if we did not handle that for you originally, please supply the stereo file along with your ADM mix. The reason for this is that the timing needs to match exactly per platform delivery specs.
