  1. I see Jonathan has some lipinski l 707 there… I am wondering if the l70 are also good for mastering – techno/ house mastering?! Or are the lipinski l70 lacking of bass?

  2. Hey Jonathan!

    Happy New Year!! Great Video!!  The course you instructed from Berklee On Line – Mastering Audio Techniques is really paying off!! It was a great investment in my skill set!!!  I have since finsihed my Masters Certificate in – Songwriting and Production and am soon to be finsishing and mastering my first CD  to be release in the next three months!!  Thank You and all the best!!!!!!

  3. Great video and great point about mastering other people's music – as well as the comment further down around "the differentiation is in the practice, not the knowledge itself".

  4. Thanks for taking us on the tour of your mastering room. Very impressive. It does leave me a little embarrassed though when I look around my "room" only to realize it's my 10'x10' bedroom. Because I'm on a tight budget, I use an imac, and it is dead silent, but gets hot enough to heat my room.

  5. I'm no pro mastering engineer, but I've found that the midrange (imo 800hz-6khz) needs to be well balanced to start with, because that's what will usually make it through every delivery medium. Then whats left is to keep low end under control to minimize modulation that will distort a mix through tiny speakers. And control the desire to use shelf EQs on the high end (6khz and up), as it will sound too tinny.
    The end user will probably have EQ in place on their device to add lows/highs anyway.

  6. Thanks Joe….I've been in those shoes and have come to realize that there is really no point in pretending that any knowledge is 'secret' or sacred. Ultimately the 'secret' is in the practice.

  7. We make the music sound as good as we can so it will survive the next step as well as possible! Imagine if it sounds awful to start and THEN gets contorted through a bad playback system. A recipe for disaster.

  8. The screen is off to the right, behind the listening position on a rolling cart and so moveable and 'angleable'….but I can't wait for the day I can get all the screens gone. Google Glass?

  9. Thanks Dwayne. Not sure what dB spec/scale you are referring to but it's certainly noisier than the NC15 noise fllor in our room…..however…that machine is almost never turned on…only used when transferring mix files/stems. Our workhorse is a MacPro/bootcamp machine in our machine room separated from the mastering lab

  10. In other words "no I have no idea what customization he did / how noisy his Mac actually is" 😉 Isn't it possible to make Mac quiet? I'm a PC guy and my machine is super quiet (hardly noticed to be on, and my room is also very quiet) using case Antec P183V3, passive graphics / CPU heatsink, quiet hard drives / fans, decent quiet LED LCD displays…
    The days of "machine room" where all that noisy machinery needed to be put, are fortunately already gone…

  11. yes in a sense, I own that model of mac pro tower and I have a similar room. …that mac would be the loudest thing in the room for sure, that's why i isolate mine. in my mix room the loudest thing is the small buzz from my main monitors that sit 10' away in a room that is 25' deep. That is how quite my room is. My mac sits behind a 6' double 2×4", air spaced batting filled wall and you cant hear it.

  12. It's so sad, really, but one of biggest stumbling blocks when it comes to my mixes is most definitely the proverbial laptop playback. Most of them turn out sounding horrendous, but through my monitors and headphones, both sound pretty decent. The first thing I think of every time I hear it on either a smartphone speaker or a laptop is " my music isn't as bad as it sounds"

  13. re: computer fan and drive noise – yes, I had the same question. In our facility, we spent a rather considerable amount of money to completely remote ALL noise generating devices away from our mastering rooms. It cost quite a bit to achieve our NC-12 noise floor.

    But Jonathan clearly has the most important three tools right where they need to be – two are on either side of his head and the third is right in between them.
