Certified Apple MFIT studio maximizes your Apple iTunes release as well as Spotify, Napster, YouTube and other streaming services.

We embrace the newest R128 measurement systems, including LUFS scale and True Peak, which are optimised for the highest fidelity and dynamic range for 21st century streaming delivery systems.


Room and Monitors

Our carefully controlled listening environment was designed by Fran Manzella of Francis Manzella Design Ltd.

Our main monitors are Dunlavy SC4a loudspeakers with custom McCormack DNA-1 amplifiers. To keep the purest signal path possible we use no active preamp.  Instead, volume levels are controlled by a Placette passive attenuator system and interconnect wires are custom designed by Ambient Labs.

Our secondary system is all vintage: McIntosh 225 tube amplifier and JBL LE8T full range alnico drivers.  There is something intoxicating about the sound of a single driver with no crossover powered by a classic tube amp.



Our rates are competitive with our esteemed competition.  But our results and attention to detail is unrivaled.

Please tell us about your project and we will design a mastering budget that fits.

Recently we overhauled our pair of Studer B76 1/4" analog tape decks.  These are fantastic sounding machines and in my opinion are superior sounding to the more known A80 series.  You owe it to yourself to hear 15ips record/playback using a B67 set up with CCIR EQ curves.   This is THE sound of Rock'n Roll!

We also refurbished our collection of analog tape noise reduction systems, including Dolby A, Dolby SR and dbx.  We are the only facility in New Mexico that offers full service record and playback of 1/2" 1/4"  widths, all tape speeds and head formats as well as complete noise reduction decoding. And of course we can bake tapes!

New addition:  we've added a Prism ADA-8XR 8 channel analog digital/digital to analog converter, significantly upgrading our analog insert and monitor path.  Stay tuned for an announcement for our new  audio computer workstation.

Congratulations to Leslie Pintchik and Scott Hardy on having their original music chosen for the soundtrack of Orson Wells's recently discovered movie "The Other Side of the Wind".  Michael MacDonald recorded, mixed and mastered this material at Ambient Recording Studios and AlgoRhythms Mastering.

Professional Tips and Advice

Save $100 at your next mastering session.


Here's how to save at least $100 on your next mastering session.

1. Choose your final mixes before before arriving at your mastering session. Sometimes that may not be possible because you need your mastering engineer's opinion or want to listen to the difference between a digital and an analog mix. But if you narrow your decisions before your session begins, you'll save money by reducing auditioning time, which is billable time.

2. Document your source material and make sure it is correctly formatted. Don't bring in a hard drive with hundreds of files with names like: 

01 track-L.aif

01 track-R.aif

02 track-L.wav

02 track-R.wav

03 track-L.bfw

03 track-R.bfw


Put your final mixes with their proper titles in a separate folder called Final Mixes for Mastering. Be sure that your titles and songs match. Failure to do this requires your mastering engineer to go fishing in order to harvest the correct files. This is a waste of his/her time, which translates into a waste of your money.

3. Make sure you know and you tell your mastering engineer ahead of time what format, sampling rate and bit depth your mixes are in. If you have mixes with different formats and sampling rates, letting your mastering engineer know ahead of time will streamline and shorten the load in process because he/she can optimise their proceedures for maxium efficiency.

4. Don't assume your mastering studio has the same kind of computer or software that you used in the mixing studio. Most Macs can read a ProTools formatted hard drive, but many PCs can't. Ask beforehand.

5. Get your mix files or tapes to the mastering studio a few days before your session. This allows the studio to check and verify, or catch a problem before your session begins. If there is a problem, there's usually enough time to fix it, preventing a missed deadline or you being billed for time that isn't productive.

6. Decide on your song sequence before the mastering session. It's okay to change your mind later, but have a first version sequence to start with. Deciding what order your songs belong in while in mastering just runs the meter unnecessarily.

7. Provide the correct title and spelling of each tune at the beginning of the session. The mastering engineer will only have to enter the proper information once, rather than have to first enter something incomplete or incorrect and then take time to correct it later.

8. Obtain your UPC and ISRC code information before the session. Don't wait until the end of your session to mention you will get them later. If you do, then more time will be needed to create a new master with the information you could have brought to the session at the beginning.

9. Prioritize your problems so your mastering engineer will know how to allocate time to best solve your most important concerns. This will help prevent your session from running over budget because too much time was spent dealing with the trivial matters first.

10. Limit those attending your mastering session to the absolute minium. Each additional person will add at least 30 minuites to your final bill. If your session turns into a "hang", you'll be paying for an expensive party rather than the creative musical finish you had hoped to achieve.

Following these steps will save at least 1 hour of billing time and produce a better final product because your mastering engineer can concentrate on being the creative professional you expect, rather than spending time and money on problems that could have been solved before your session began.

Stay Tuned

Why Santa Fe?



I’ve loved Santa Fe since I went to college here. And when I graduated, I promised myself that someday I’d come back to stay. After 30 years of a successful career recording, mixing and mastering in New York City, it was time for a change.

As much as I love New York, I don’t miss the crowded subway commute or the noise. I traded that for a ten-minute drive to work, where I see snow capped mountains and breathe clean air. 

My clients hail from around the world and usually don’t attend sessions; it doesn’t matter to them where I do my work. And I’m delighted to meet new friends and clients from the Southwest who need my mastering skills.

I have to admit that I miss two things from New York City: my old friends and good sushi…delivered!

Honestly, I couldn’t be happier than I am in Santa Fe, providing world class mastering services to the Southwest and fulfilling a long-standing dream.
