Music Note Frequency Calculator With Cent Adjustment

A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”

Sounded like the kind of math challenge I like:

The answer is 452.893Hz

To test and confirm that it’s calculating properly, this is up 100 cents making G# 440

This is down 100 cents making A# 440

Dolby atmos

I was lucky enough to get to visit the new Atmos mix room at Deluxe Toronto.  This was the deadest big room I’ve ever been in.  It was impressive to hear the system.  Being a part of the AES gave me an incredible experience of A/B-ing the new IMAX mix room at Technicolor and the Atmos room at Deluxe.   In my opinion the ideas of IMAX immersive technologies translate much better.   The guys at IMAX got it right.

They had a guy from dolby explaining a little about how Atmos renders… very interesting how it translates from room to room.

IMAX- The Next generation of IMAX sound – 12 Channel configuration – and LASER projectors, about time

Imax – The Next generation of IMAX sound –  12 Channel configuration – and LASER projectors, about time!!

Had a fantastic experience with the new IMAX sound system at the AES meeting held at Technicolor.

The “Upper Quad” ceiling speakers really bring it together.IMG_8687

VBAP is going to need some work… and a HUI

I walked away asking: “If it were truly immersive, there would never be idle speakers”  Cory said: “Backgrounds are the first thing to go…” I think those will become crucial.

I also walked away wanting a dozen U87s…

Of course you could hear the birds chirping and running away WHILE the rocket was launching…

JL Sub-Woofer

Took a look inside a JL subwoofer… quite the coil and suspension system.  http://www.jlaudio.ca/home-audio-powered-subwoofers-fathom

JL audio dominates the Car stereo market in terms of driver quality.  The salesman said the best line “We learned a lot from our 12 Volt line of products in designing this home theatre sub”  so from now on, Car audio will be forever “the 12 volt industry”

rom the sale:

 

Up for sale is a rare 1970’s Philips LDC25 console. The console features 24 transformer balanced mic/line inputs, great sounding 3 band EQ, 2 aux sends per channel and 4 transformer balanced output busses. 16 of the input channels are early discrete LDC modules and the last 8 feature later 1970’s IC based modules – both sets of modules sound, for all intents and purposes, identical. The sound of this desk is punchy, clean and very hi-fi sounding – easily on par with anything built by Neve/Api/Studer from the same era. These were built by Philips in Holland for recording mostly classical music, but were built to a very high standard and also sound fantastic on modern tracks which require a very forward sounding mix with a very low noise floor. I bought this to use as the main console in our studio due to the high build quality, high track count, compact size, multiple sends and versatile output options – but I need to raise money for the completion of our house restoration which takes priority to the studio build out. All the manuals and module documentation are included. The console will be fully gone through by a qualified technician prior to shipping and/or pickup. All input/output wiring is terminated to panel mounted XLR connectors, so all you need to do is connect the console to your DAW/tape machine and you are ready to record – no wiring necessary.
The console is located two hours west of Chicago in IL. I’m happy to assist with freight shipping, but please understand due to the fragile nature of vintage electronics any risk associated with shipping is going to be your responsibility. Local pickup is welcome. Payment by check or wire transfer only for this listing. Please feel free to contact me with any questions you might have. I hope this console finds a good home!

Moving stuff across the country

I most certainly had a busy “reading week”.  It started with finishing up a job My brother Mike started.  Moving 7 pallets of equipment from my moms garage in Saskatoon.    Followed by great visits with Family and friends.  I’m sorry I did not get the chance to meet with everyone I had planned to visit with.  Things got a little busy in the IT support world and there was so much family to visit!

Three consoles were packaged and palleted up for shipment across the country.

Custom made dollies were built for the two large sections of console frames.

Modules were packed, boxed and palleted.  A small fortune in bubble wrap and pallet wrap were employed.

I’m excited to work on these projects again in my “Spare time”

Stay tuned for updates of what’s happening with this lot.  We’re very excited for what’s planned :-)

Ward-Beck Systems “DINNER BOXES” dB-4

Well after some time away, I’ve gotten back to the Dinner Box

The dinner box is a PCB that users can solder EDAC connectors that mate with Ward-Beck Systems Auxiliary modules.

With a standardized 5 PIN XLR power connector, users can simply power up (4) WBS filters and Compressors.

In Addition to power and audio, there is the interconnections stereo linking of the M466 compressors using either M466M OR M467 Noise gate modules.

the dB-4 also allows user to mix and match equalizers: any of the M462, M462A, M462B or M464 Filter interchange seamlessly into this bucket.

A balancing card for M472 eq modules is on the drawing board.

Here is a revised version.
The major change is the addition of XLR connectors… The idea of using a dB25 connector is now optional!
