Tin Pan Alley - Denmark Street

Packing some equipment today for the move to the new studio, I came across this label. It has some history behind it. It came from the box for my Sequential Circuits Pro-One synthesizer, and shows where I bought it from. Denmark Street in London, otherwise known as the British Tin Pan Alley.

Denmark street was originally residential, but became used for commercial purposes in the 19th century. At first, metalwork was a popular trade but it became most famous as Britain's "Tin Pan Alley" housing numerous music publishers' offices. This market declined in the 1960s to be replaced by music shops and independent recording studios. The Rolling Stones recorded at Regent Sound Studio at No. 4 and popular musicians, including David Bowie and the Small Faces, often socialised in the Gioconda café at No. 9.

Elton John and Bernie Taupin wrote songs at offices on the street in the 1960s, while the Sex Pistols lived above No. 6, and recorded their first demos there.

Session musicians such as Jimmy Page and John Paul Jones regularly played in Denmark Street studios. In 1964, The Kinks recorded "You Really Got Me" in one of the basement studios.

The sheet music shop Argents is currently based at No. 19. It was founded by The Zombies' Rod Argent (later to form the group ‘Argent’) as a keyboard shop and was previously based next door, at No. 20. Since then it has undergone two changes of owners and now specialises in sheet music and DVD sales, covering a wide variety of styles including jazz and classical.

THX Deep Note

If you've been to the cinema anytime since 1983 you may have encountered the THX logo telling you that your cinema is THX certified and the audio experience you are about to hear will be incredible. The three letter logo is one thing, but the accompanying audio logo sound, known as the Deep Note is unforgettable. The famous note was composed by Lucasfilm sound engineer Dr. James 'Andy' Moorer the logo was first screened at the start of the 1983 premiere of Star Wars: Episode VI - Return of the Jedi.

The U.S. trademark registration for the first version of the sound contains this description of it:

The THX logo theme consists of 30 voices over seven measures, starting in a narrow range, 200 to 400 Hz, and slowly diverting to preselected pitches encompassing three octaves. The 30 voices begin at pitches between 200 Hz and 400 Hz and arrive at pre-selected pitches spanning three octaves by the fourth measure. The highest pitch is slightly detuned while there are double the number of voices of the lowest two pitches

I have used the THX Deep Note many times in theatre situations as a way of assessing the acoustics and audio capabilities of the installation.

History

In 1980 George Lucas wanted the best sound system possible for the premiere of his latest Star Wars film, The Empire Strikes Back.

The usual sound systems of the day comprised left, centre and right speakers behind the screen and an additional surround speaker. When his engineers investigated one of the old Majestic cinemas in San Francisco they were horrified to find that of the three speakers behind the screen one was disconnected, one had fallen over and the other was turned around backwards. The decision was taken to come up with a standard to ensure that cinema sound quality was as good as it was in the film mixing suites. George used his power to insist that any cinema that wanted to show his films needed to become THX certified.

Dr. Andy Moorer had already spent two years designing and programming a computer that was powerful enough to deal with the mathematics needed to create rich natural sounds which were more than the bleeps and bloops of the Ataris of the day, so it was natural for him to use his work when he was asked to create the THX sound.

What is THX certification?

The THX certification does not concern any encoding of decoding of the sound itself. It covers the following 4 areas: 

  1. Auditorium - isolation between auditoriums, interior acoustics, background noise requirements (air conditioning, projector)

  2. Equipment - speakers, amplifiers, projectors

  3. Configuration - where is the equipment placed

  4. Calibration - testing that a cinema meets the THX requirements

The THX Sound

The sound starts with chaos and rises to a huge chord, similar to the sound produced by large pipe organs. When developing the sound Andy was influenced by Bach fugues and the end of A Day in the Life by The Beatles.

The first Deep Note was generated using random numbers meaning that each time it was played from the computer it was slightly different. Every second each of the 30 voices was assigned a new pitch to work towards until the point when they were given their final target pitch resulting in the final chord. Each note is slightly detuned to give the final chord its fullness. The tuning used is not equal temperament (each of the 12 notes being equally spaced) but uses Pythagorean tuning (used around the middle ages but doesn't easily facilitate key changes)

Listener reaction

Thomas Dolby describes the sound as:

a sound emerging from the primordial soup of molecules of carbon and water vapour and ether. By alchemy, these are brought together into this pillar of the final chord. It's like building structure from chaos.

Others have said:

the THX logo is the single most terrifying thing ever.

The THX audio logo has become so well known that there have been several other versions made for TV and film.

 

James A. Moorer said in a 2005 interview:

I like to say that the THX sound is the most widely-recognized piece of computer-generated music in the world. This may or may not be true, but it sounds cool!

Innovation

Two new versions were produced but neither were successful.

In 2015 THX decided to produce a new version of the original using new state-of-the-art equipment.

Andy re-coded the entire program using the C language and because of computer advances he was now able to run it on his home computer. He developed alternative versions using more voices for the different cinema setups. The standard stereo version still used 30 voices but for 5:1 he used 40 voices, 7:1 used 60 and 9:1 used 80. The sound also now moves spatially around the room.

New 2201 single release

I’m pleased to announce that the first track from a forthcoming album has been released today. The single will become part of the ‘Numbers’ album and is called ‘15728

At the moment the world seems to become more dangerous each week as our leaders seem happy to casually threaten others with little concern for the possibility and danger of escalating situations. With this situation in mind I took a look at the secretive and scary world of Numbers Stations.

The one-way voice link (OWVL) described a covert communications system that transmitted messages to an agent's unmodified shortwave radio using the high-frequency shortwave bands between 3 and 30 MHz at a predetermined time, date, and frequency contained in their communications plan.

US PRESIDENT Donald Trump's decision to withdraw from a key nuclear treaty with Russia on Friday represents a significant "long-term" threat to NATO and its European allies, a former US official argued last night.

The Secrets about Numbers stations

Since World War II, so-called Numbers stations have been transmitting coded messages using shortwave radio antennas. These transmissions sound weird and somewhat spooky to most listeners, impossible to decode to cryptographers, but to the intended recipient may contain information that changes the course of history.

Simple SW radio

Simple SW radio

Numbers stations are simply shortwave radio transmitters usually operating between 3,000 and 30,000 kilohertz and are possibly pirate stations which operate unlicensed leaving them absent from any government documents. If they are not pirates, then who is authorizing them? If they are pirates, then what audience are they transmitting for? Using Short Wave radios will never arouse any suspicion unlike the use of more sophisticated computer equipment.

The broadcasts generally begin with an alert signal which may be a simple tone, or it can be fragments of a song, such as with the famous Lincolnshire Poacher station, which begins broadcasts by playing several bars from the well-known tune of the same name. Others include Magnetic Fields (Jean Michel Jarre), Swedish Rhapsody, Cherry Ripe. This indicates to listeners that a message is about to begin.

Number stations use a system which is absolutely secure. A so called ‘One Time Pad’ provides the key for encryption and decryption using a string of numbers as the key. After use the code is destroyed meaning that no part of the key is ever reused.

Not all Numbers stations send out simple numbers. Some of them send out noises instead. The station known as ‘The Buzzer’ sends out high precision buzzing on 4625khz 24 hours a day, every day of the year. It has been on the air for over 10 years with no information about its source.

Here is an example from the Swedish Rhapsody station

The Conet Project released a set of CD’s with recordings of Numbers Stations and Noise Stations based on the work of Numbers Station enthusiast Akin Fernandez .

Numbers Station transmissions have become popular with music and filmmakers. Notable among them are Boards of Canada (album Geogaddi track Gyroscope), Max Richter (most of the album The Blue Notebooks), Jóhann Jóhannsson (album Orphée track A Song For Europa) and the film The Numbers Station starring John Cusack and Malin Åkerman

Gilets Jaunes - binaural recordings

I stumbled across this remarkable work of audio field recording by Benjamin Gale a freelance Sound Editor, Field Recordist and Sound Designer currently based in London. Not only are these extremely good binaural recordings of the current civil unrest in France, known as the ‘gilets jaunes’ (yellow jackets), but show a good deal of bravery in pursuit of the art.

Only pockets of casseurs remained

KiloHearts Phase Plant is sounding very good

This is all sounding very nice. Coming soon! Phase Plant is the crowning achievement of the snapin eco-system that Kilohearts have been developing since the release of Multipass in 2015.

Phase Plant combines the power of or snapin effects with new modules for signal generation and modulation, creating a hybrid synthesizer capable of what has previously only been possible in classic modular setups. It does all this on a single screen and with surprising ease.

KiloHearts Phase Plant interface

The way the different elements go together gives a lovely modular feel, and allows some spectacular sound generation ideas to be generated when you move the placement of the modules around. For me, possibly the most impressive aspect is the graphics, which are really well done and help to explain the effect of the different modules by giving visual feedback.

KiloHearts plan to have it ready for Spring 2019

Sadowick has done a nice job of explaining it here
