From 'My Blue Heaven' to 'Race with the Devil': echo, reverb and (dis)ordered space in early popular music recording. Doyle. P. (2004)

Doyle (2004) discusses that fact that echoes have a mystical quality then analyses various recordings from the period of 1920 through to the 1950’s looking at the use of spatial effects.

“Reverberation does much to define what we perceive as timbre, volume and sound colouration, and largely determines our perceptions of directionality and nearness.” (Doyle 2004 pg.3)

“Recordings became capable of picking up room ambience, of carrying, in other words, significant sonic information about the spaces in which they were made. Of this last point, Gelatt says:... the 'atmosphere' surrounding music in the concert hall could now be simulated on records. Musicians were no longer forced to work ... directly before a recording horn but could play in spacious studios with proper reverberation characteristics.”  (Gelatt 1977, p . 223)

“Increasingly during the late 1940s and early 1950s, some producers and musicians began to use echo effects to render unfixed, or (at least in part) anti-linear, self-consciously weird and/or futuristic spaces. And certain of the older style pictorially anchored spatial recordings during this period began to display an increasingly exaggerated pictorial field, as echo and reverb effects changed (in some cases at least) from being a covertly used producer's technique to an increasingly emphasised, featured gimmick.” (Doyle 2004 pg.9)

“Les Paul arguably did more than any other single operator in the recording industry to break the 'authenticity nexus' between the actual performance and the final recorded product, and some of his most arresting devices involved deliberate spatial plays.” (Doyle 2004 pg.10)

Spatial Effects and Their Uses in Dub

In order to investigate how the spatial effects used in dub have influenced other genre first we must define what effects are used to create the illusion of space and how they have been used in dub.
Reverberation is the most commonly used effect used to create space. Izhaki (2012 pg.405) describes reverb in the following way, 

“In nature, reverb is observed mostly within enclosed spaces, such as rooms. Reverbs are easier to understand if we imagine an impulse sound, like a hand clap, emitted from a sound source in an empty room. Such a sound will propagate in a spherical fashion and for simplicity we should regard it as travelling in all directions. The emitted sound will travel in a direct path to a listener (or a microphone) followed by reflections that bounced from the walls, floor and ceiling. These will be gradually followed by denser reflections that have bounced many times from many surfaces. As sound both diminishes when travelling through air and being absorbed by surface materials, the reflections will slowly decay in amplitude. Reverb is the collective name given to the sound created by bounced reflections from room boundaries (which we consider to be the main reverb contributors, although in a room there might be many surfaces). In mixing, we use reverb emulators, either hardware units or software plugins, to simulate this natural phenomenon.” 

“Each time a waveform reflects some energy is absorbed by the surface and each time a waveform is diffused the energy is divided among the reflections and so over time the amplitude of reverberation decays until it is inaudible. As sound takes time to travel around a room (344meters per second at room temperature) each reflection arrives at the listener later than the last reflection and so the reverberation is audible for a longer period of time than the direct original sound. Diagram 1 below shows the decay of reverberation overtime.” (http://www.magicmess.co.uk/electronics/spring.php)


The amount of reverb in a space is dependent on the volume of the room but also the rate at which sound is absorbed by walls and other surfaces.

Wallace Sabine did some pioneering research in this area and came up with a formula that relates the quality of a room’s acoustic with the size of the room, and the amount of sound absorption surfaces present.

His formula calculates the reverberation time which is defined by the time taken (in seconds) for a sound to drop by 60 decibels.
RT60 = 0.161(V/Sa)

V is the volume of the room in cubic meters. This is divided by the total absorption of the room expressed in Sabines which is calculated by the sum of all the surface areas in the room multiplied by the absorption coefficients for each material.

A characteristic dub reverb sound is the spring reverb. The spring reverb works by using the physical movement of a spring to generate the reflections.

Delay is another common effect used to create space in audio recordings. Hodgson (2010 pg.124) states “the simple delay line is the building block of all delay processing techniques.” Then continues to describe how audio signals are fed into a delay line where the signal is split and a copy is stored for a certain amount of time before being passed to the output after the direct signal.
All delay units and plug-in effects have 3 basic settings which are the Delay time or the amount of time between the input signal and the copy arriving at the output. The mix setting which adjusts the balance between the input signal and the delayed copy. And the feedback which controls the amount of the delayed signal which is routed back to the input. Hodgson (2010) states that recordists have created a “staggeringly diverse array of musical techniques” by adjusting the 3 parameters listed above.

 A common delay sound used in dub is the tape delay. Case (2007 pg.224) states that

“Before the days of digital audio, a common approach to creating delays was to use a spare analogue tape machine as a generator...During mixdown the machine is constantly rolling in record mode. The signal is sent from the console to the input of the tape machine...That signal is recorded at the tape machine and milliseconds later is played back...(the tape machine) remains in repro mode so the output is what it sees at the playback head...The signal goes in gets printed onto tape the tape makes its way from the record head to the playback head (taking time to do so) and finally the signal is played back off tape and returned to the console. The result is tape delay.” 

Analogue tape delay also adds tape saturation and tape hiss, these sounds have also become a highly sought after additional qualities of tape delay. Many hardware and software emulators try to recreate these qualities of tape delay and one such emulator used significantly in the production of dub is the Roland RE 201 Space Echo which uses a magnetic tape loop to simulate tape delay.

Another aspect of the use of space is creative sound staging. Moylan (2008) states "The sound stage is the singular area occupied by all of the sound sources of the music, as an aggregate or group.  It has an apparent physical size of width and depth that are defined at the level of the individual sound source: (1) the dimension of width is defined by the furthest right and left sound (lateral localization) and (2) the dimension of depth is defined by the most distant sound source and the closest sound source."

Zagorski-Thomas (2010) takes this idea of the sound stage further to functional staging “Functional staging is a concept building on the idea of phonographic staging developed by William Moylan and Serge Lacasse and related to Allan Moore’s ‘sound-box’. The staging of sounds in the record production process is considered to be functional if the reason for their particular placement or treatment is related to the practicalities of audience reception rather than to aesthetics.” (Zagorski-Thomas 2010 pg.1) 
“Functional staging relates to the size of the perceived space and the perception of distance rather than lateral placement.”  (Zagorski-Thomas 2010 pg.6)

Dub Revolution: The Story of Jamaican Dub Reggae and Its Legacy.

Written by John Bush

Useful Quotes

"The great sound system engineers of Jamaica in the late 1960s and early 1970s pioneered theinstrumental remix and were the first to make the style popular. Using only primitive recording and mixing equipment, the mixing engineer took a lead role in defining the sound of the recording, using the mixing board as his instrument.” (Bush)

“Ruddy played a key role in the initial development of dub, as he was the first to make a public performance of what would become known as version - the instrumental mix of a song without the vocals.” (Bush)

“Scratch later built his own studio, the legendary Black Ark, in 1974 in the Kingston suburb of Washington Gardens. Under Perry’s guidance, the Black Ark became known for its signature sound that was quite different from the other studios. From 1974 to 1979, the Black Ark was a center of creativity in reggae music, with Scratch continuing to experiment in version and dub styles. The Black Ark sound was characteristically heavy yet uplifting at the same time.” (Bush)


The development of the genre dub took place when the engineer would take an instrumental version of a track to the next level, using the effects such as echo, reverb and delay to change the whole sound and texture of the riddim. “This was the turning point in which dub emerged as a unique and characteristic branch of music itself, and can be credited almost entirely to the contributions of a mixing engineer known as King Tubby.” (Bush)


Tubby who was experienced in electronics through his background in TV repairs customised his mixing desk at his studio in the ghetto district Waterhouse in Kingston, adding faders which allowed him to add or subtract the various elements of the tracks smoothly. He also created his own effects units by modifying tape machines to create delays and hitting spring reverb units which created the characteristic thunderclap sound used in dub. “Tubby’s innovations behind the mixing board introduced to Jamaica the idea of the mixing engineer playing a creative role in the music.” (Bush)


Prince Jammy and Scientist who were trained by Tubby at his studio were the next generation of dub engineers. “Prince Jammy, otherwise named Lloyd James, would eventually go on to become one of the most successful producers during the dancehall era that Jamaica was soon to enter.... Using Tubby’s equipment, Jammy’s dubs would have the characteristic sound of Tubby’s studio, but in a style of his own. Jammy’s dubs were often more stripped down than Tubby’s, emphasizing the groove of the drum and bass, or the riddim.” (Bush)




The Representation of Space in Audio and Audiovisual Works. Bates (2007)


ARP Conference Paper

This paper discusses the construction of space with sound and the arrangement of elements within that space, and compares the use of space in audio recording and film sound.

“For example, voices are treated differently in the two media, albeit they cross-pollinate. A reverberant voice in the iconic Chess or Sun rock ‘n’ roll music style is not generally employed in cinema and would not be read the same way. Reverberant voices tend to be used in film voiceovers to represent inner thoughts or might be used to evoke an eerie, uncanny or disembodied threat, or, if synchronised to picture, perhaps a visiting alien or malevolent spirit rather than the teenage angst of the spirited outsider or their chorus.” (Bates 2007 pg.1)

“In the ancient world there were deep linkages between reverberant space and the sacred or magical.” (Bates 2007 pg.2)

“And so, in those early recordings, as Peter Doyle argues, the recordings “came imbued with their own spatial codes; they constructed their own proscenium arch” (Doyle 2005:50) with the various placements of instruments and the content of the music composition constructed to superimpose fictional “sound pictures” onto the playback space- or at least that was the promise.” (Bates 2007 pg.4)


Natural audiotopias: The construction of sonic space in dub reggae. John Baker (2009)


ABSTRACT 

Dub reggae is widely regarded as an early form of the remix. Dub artists modify 
previously recorded reggae songs by manipulating a song’s individual tracks with a 
mixing board and layering them in aural effects such as reverb and echo. These effects 
are fundamentally spatial in quality, giving the listener an impression of vast open space. 
This paper is an analysis of the techniques utilized in dub’s construction of sonic space as 
well as an investigation of the cultural meaning of those spaces. My analysis utilizes 
Josh Kun’s theories about “audiotopias” (temporary aural spaces created through music) 
in order to study how sonic spaces create “new maps” that allow an individual to analyze 
their current social predicament. These “new maps,” therefore, engender a “remapping” 
of reality, a reconstitutive process that parallels dub’s emphasis on modification and 
alteration. This paper also argues that dub’s audiotopias are implicitly natural, although 
they are constructed through modern recording technologies such as the echo chamber 
and the reverb unit. A final chapter applies these analytical techniques to one of dub’s 
most popular musical offspring, hip hop.1

“In order to study how sonic spaces create “new maps” that allow an individual to analyze their current social predicament. These “new maps,” therefore, engender a “remapping” of reality, a reconstitutive process that parallels dub’s emphasis on modification and alteration.” (Baker 2009 pg.ii)


"In 1976, Melody Maker published an article by music critic Richard Williams entitled “The Sound of Surprise.” Williams’ essay was a short but prescient description of the still-shockingly-new phenomenon of dub reggae. Williams prophetically noted that “there are possibilities inherent in this aberrant form which could perhaps resonate throughout other musics in the years to come” (145). (Williams 1976 quoted in Baker 2009 pg.5). 
This statement demonstrates that from the beginnings of early dub an interest was taken in its innovative production techniques and how these techniques could possibly influence future music. EDM is a good example of a genre that has taken influences from dub's use of space and spatial effects and used it to create new sonic spaces, soundscapes or audiotopias. 

Baker (2009 pg.27) describes Tubby's reverb technique in the following way "Tubby’s percussive use of reverb “widens” the track, giving the listener an impression of deep canyons and limitless plains."

"Doyle’s assertion that natural reverberant spaces can possess sacred qualities has particular implications for Jamaica’s Rastafarians, whose belief in the “ital” (natural) stresses humanity’s spiritual connection to the earth." (Baker 2009 pg.23).
Dub artists with a strong connection to the Rastafarian religion were looking to create this connection with “the other” or to create something new and unheard before which could give them the edge in a "sound clash" between two competing sound systems.

Baker (2009) uses “Josh Kun’s theories about “audiotopias” (temporary aural spaces created through music)” to describe dub’s soundscapes created with the use of echo and reverb effects. “In order to study how sonic spaces create “new maps” that allow an individual to analyze their current social predicament. These “new maps,” therefore, engender a “remapping” of reality, a reconstitutive process that parallels dub’s emphasis on modification and alteration.” (Baker 2009 pg.ii). The use of reverberation and delay effects along with creative mixing and soundstage techniques combined an extra spatial dimension creating strange dub soundscapes that had not been heard before and with an emphasis on the rhythm section, this has become the characteristic dub sound. "Dub artists utilized reverb to construct sonic spaces that sounded as if they were free of human impediment and therefore full of possibility." Baker (2009 pg.26).
Baker then goes on to describe how dub’s audiotopias can be described as natural which is problematic as these alternate spaces which are created, serve to remove the listener from the everyday, therefore cannot be described as natural. Also Baker contradicts himself with this statement by talking about giving the listener an impression of deep canyons and limitless plains. The spaces created through the creative use of effects in dub were never meant to be natural, with the help of the previously mentioned effects Dub artists were able to create impossible soundscapes or audiotopia’s which do not relate to any real world acoustic spaces.

"Dub’s rhythmic decentring,"..."can be read as simply another example of the genre’s emphasis on fragmentation. Dub’s echoic alternate rhythms are never fully established, after all. They do not overtake the rhythmic foreground but instead remain within the song’s defining background, influencing the listener’s awareness of sonic space. They are incomplete, offering only a hint at the possibilities offered by the audiotopia." (Baker 2009 pg.41).
