, the stage was altered acoustically with five double plywood partitions that separated the sections of the orchestra. Although a satisfactory recording was made, the musicians could not hear the other instruments clearly enough and this affected the tempo of the piece. Poor control over the separation of low frequency sounds presented a further problem on playback of the music.

As production costs for The Sorcerer's Apprentice surpassed $125,000, it became clear to Disney that it would not recoup costs as a short. In February 1938, he decided to expand the concept and start on a feature-length film consisting of several animated segments named The Concert Feature. The title was changed to Fantasia at the suggestion of Stokowski.

Recording the Fantasia soundtrack (1939)

In January 1939, Stokowski signed an 18-month contract with Disney to conduct the remaining pieces for Fantasia. Fascinated with the rich sound he heard at Culver Studios, Disney felt the conventional sound systems at the time sounded too tinny and inadequate for the experience he wanted Fantasia to be.

The goal was to reproduce a full symphony orchestra with its normal volume range and acoustic output in the theatre. The set-up used for the recording of The Sorcerer's Apprentice was abandoned, and it was decided to record with the Philadelphia Orchestra

 machines located in the hall's basement. Several safety measures were enforced to prevent the risk of fire as the Academy was constructed of wood. A maximum of 18 rolls of raw nitrate film stock were allowed in the venue at any one time, with a film delivery truck parked outside the hall being converted into a storage unit for a sufficient quantity of film. Six of the channels recorded different sections of the orchestra which provided a "close-up" of the instruments – cellos and basses, violins, violas, brass, woodwinds and tympani – while the seventh channel recorded a mixture of the first six and the eighth captured the overall sound of the orchestra at a distance. A ninth channel added later provided a click-track function to help the animators time their drawings to the music. Each microphone was channelled to a central switching panel, where an operator would read the score and mute those that were not in use to keep noise and leakage to a minimum. Engineers in the basement used headphones for sound mixing and cathode ray

 where tone adjustments were made. The nine recorded sound tracks were then mixed into four – three for the music, voices and special effects and the fourth for control of the volume of the first three.

Pan pot and Togad device

The average monaural sound system around the time of the production of Fantasia had a number of disadvantages. Their limited range in volume was ineffective as symphonic music was impaired by excessive ground noise and amplitude distortion. Their single point source

 of sound, though suitable for dialogue and action at the centre of the screen, caused music and sound effects to suffer from acoustic phase distortion which is absent when sound originates from multiple sources. Led by William E. Garity, the chief audio engineer at the Disney studios, technicians developed a multi-channel reproduction system that was dubbed Fantasound, a process that was to be a desirable alternative sound system.

The first task was to create the illusion of sound "moving" across neighboring speakers. It was found that by placing two speakers roughly 20 feet apart it was possible to produce a "moving" sound, but the effect could not be achieved through simple volume control. The problem was solved with a three-circuit differential junction network named the "pan pot

, the difference in volume between the loudest and quietest sounds. The dynamic range of typical film soundtracks at the time was limited to a poor signal-to-noise ratio of about 40dB. This was tackled by increasing the volume during loud passages and reducing it during quiet ones, to which the dynamic range would increase. A tone-operated gain adjusting device, or "Togad", was built that varied the volume of the replayed sound under the control of a tone of varying amplitude. This device was the predecessor of the automated mix-down systems found in modern recording studios.

Fantasound set-ups

Ten different Fantasound setups were built and tested during its development. As many as several hundred designs were detailed on paper, each with different equipment combinations. The first set-up that was constructed, the Mark I system, used a left, center and right speaker placed across the stage with two in each corner at the back of the auditorium. It used two sound channels, one directed at the stage center (or "screen") speaker, while the second could travel around the remaining four across the room smoothly using a manually controlled four-circuit panpot. The following Mark II configuration used a third sound channel and three additional speakers, two placed on each side wall of the house and a third placed in the middle of the ceiling, all with a manual six-circuit panpot. By the time the Mark II system was devised, the control of the sound system was too complex for a single operator. To avoid such difficulties, the Mark III system was developed to study the effects of a pilot tone-control track. The configuration was a single-channel Togad expander, controlled by either an oscillator or a tone track. The Mark IV system was identical to the eight-speaker, three-track Mark II system except that a Togad replaced manual control. It was installed at Disney's Hyperion studios in the summer of 1939 and was used for sound and music department research until Disney's relocation to Burbank in 1940. The equipment for this system required a floor space of about 35 feet by 4 feet and used nearly 400 vacuum tubes.

The Mark V system, the first installed at Burbank, was in operation for one day. Though the equipment operated correctly, it failed because the personnel could not remember the correct configuration from one rehearsal to the next. The crew then developed the simpler Mark VI setup that consisted of three stage speakers, three program tracks and a three-tone control track. The first serious dubbing of Fantasia was attempted on this system. The Mark VII was the first to be manufactured by RCA

 that closely resembled the Mark VI, but included tone rectifier modifications. The Mark VIII system was a rearranged version of the Mark VII. A log-log tone rectifier designed by RCA replaced the linear tone rectifier used in the Mark VII. The second dubbing of Fantasia was done through this system. Following the installation of a stand-by channel, this equipment was installed in New York City for the film's premiere. Two further systems were developed after the film's opening. The arrangement of the Mark IX setup was changed and two sets of rear speakers were manually switched in to supplement or replace the left and right front speakers at several points in the film. In the Mark X, the switching and level changes in the rear speakers are done automatically using a thyratron and mechanical relay system operated by means of notches on the edge of the film. This was developed by Disney engineers C. A. Hisserich and Tickner. Disney became an early customer for the newly-established Hewlett-Packard

's Watson Jones later gave these reasons:
  • The amount of equipment required and the time necessary to make the installation.
  • Because of the time element attractive theaters were not available to us, as the first-class houses in the various communities had established policies and the installation of the equipment would generally require darkening the house for a few days.
  • The advent of wartime conditions precluded the possibility of developing mobile units that would have lessened installation time and costs.
  • The variation in the regulations throughout the country, both as to operating personnel and local ordinances, materially affected the operating and installation costs.
  • Space factors of the projection room in particular were problems of major importance.

Legacy

Fantasound marked the first use of the click track, overdubbing of orchestral parts, and simultaneous multi-track recording. Almost a fifth of the film's budget was spent on musical recording techniques.

Fantasia was re-released multiple times, with the full-length version making a return to theatres in 1946. Stereo sound was not restored until its 1956 release when it was also presented in SuperScope, an anamorphic

. To create the stereo soundtrack the original tracks were transferred across telephone lines from the optical Fantasound equipment to the new magnetic recording equipment. These were housed in separate buildings and could not be brought together. This wire transfer resulted in some loss of treble response, but the copies retained the original dynamic range.

For Fantasias 1982 issue, the original recordings were abandoned all together and a completely new soundtrack was recorded using digital stereo technology, conducted by Irwin Kostal

for the film's 1990 theatrical release. Disney audio engineer Terry Porter spent six months restoring the Stokowski soundtrack. He used remastering technology to remove some 3,000 pops from the four-track magnetic copy from 1955, with tools also used on phasing, hiss and distortion. "I proposed to management that we could piece the soundtrack together...in a way that re-created the impact of the original roadshow. When we play it back...it exactly simulates the way their equipment played in the theaters...back then." The result, named "Fantasound 90", was only set up in two theaters, one each in New York City and Los Angeles. The six-channel surround print that Porter created was used as the basis for the master soundtrack of the film's DVD release in 2000.
