John G. Frayne

John G. Frayne (July 8, 1894 in Ireland – October 31, 1990 in Pasadena, California) was a physicist and sound engineer.


Frayne received his Ph.D. in physics from the University of Minnesota while working at the Bell Laboratories. In 1928, he went to California Institute of Technology as a National Research Fellow in Physics.

In 1949, with Halley Wolfe, he wrote the classic textbook Elements of Sound Recording.

Among his technical achievements were the development of sound recording techniques and their reproduction for optical sound recording systems, which led to stereo-optical formats used by films in the 1970s and '80s. He was a co-inventor of the sphere densitometer, which won a Scientific or Technical Academy Award in 1941. He was also the co-inventor of the stereo disc cutter which was standard in the recording industry, and the co-inventor of the inter-modulation techniques of distortion measurements, which won him an Academy Award in 1953.

He was awarded a Gordon E. Sawyer Award (Oscar statuette) by the Academy of Motion Picture Arts and Sciences in 1983.


Dr. Frayne, a Fellow of the Audio Engineering Society (AES), received its Gold Medal Award for Outstanding Achievement in advancing the art of audio engineering in 1976. He received the SMPTE Progress Medal in 1947.

52nd Academy Awards

The 52nd Academy Awards were presented April 14, 1980, at the Dorothy Chandler Pavilion in Los Angeles. The ceremonies were presided over by Johnny Carson who, in noting the long duration of the production, joked that President Jimmy Carter was working hard for their "release" from the ceremonies, a clear reference to the Iranian hostage crisis.

Among the nominees for Best Supporting Actor were 8 year-old Justin Henry—the youngest Best Supporting Actor nominee ever—and 79-year-old Melvyn Douglas. This was the largest age difference between two competing actors in Oscar history until 2013. Their age difference was partially the reason why Douglas did not attend the Oscars that night, despite winning the award. Henry was nominated for Kramer vs. Kramer, which out of its eight other nominations, finished with five awards, including Best Picture, Best Director for Robert Benton, and Best Actor for Dustin Hoffman.

Audio Engineering Society

Established in 1948, the Audio Engineering Society (AES) draws its membership from engineers, scientists, other individuals with an interest or involvement in the professional audio industry. The membership largely comprises engineers developing devices or products for audio, and persons working in audio content production. It also includes acousticians, audiologists, academics, and those in other disciplines related to audio. The AES is the only worldwide professional society devoted exclusively to audio technology.

The Society develops, reviews and publishes engineering standards for the audio and related media industries, and produces the AES Conventions, which are held twice a year alternating between Europe and the US. The AES and individual regional or national sections also hold AES Conferences on different topics during the year.

Delta Kappa Alpha

Delta Kappa Alpha (ΔΚΑ) is a national gender-inclusive cinematic professional fraternity founded in 1936, at the School of Cinematic Arts at the University of Southern California in Los Angeles, California, United States.

According to USC's cinema website, "Recognized by the School of Cinematic Arts as the official professional cinema fraternity at the University of Southern California, DKA engages the community through philanthropic, social, and professional events. The goal of this gender-inclusive fraternity is to establish meaningful relationships and camaraderie between students highly committed and interested in the film industry and in the cinematic arts."

Gordon E. Sawyer Award

The Gordon E. Sawyer Award is an Honorary Award given by the Academy of Motion Picture Arts and Sciences to "an individual in the motion picture industry whose technological contributions have brought credit to the industry." The award is named in honour of Gordon E. Sawyer, the former Sound Director at Samuel Goldwyn Studio and three-time Academy Award winner who claimed that a listing of past Academy Awards, arranged both chronologically and by category, represents a history of the development of motion pictures. It was first presented at the 54th Academy Awards, in April 1982. The Gordon E. Sawyer Award is voted upon and given by the Scientific and Technical Awards Committee of the Academy.

John A. Bonner Medal of Commendation

The Academy of Motion Picture Arts and Sciences awards the John A. Bonner Medal of Commendation upon the recommendation of its Scientific and Technical Awards Committee. The medal is awarded with a citation reading "in appreciation for outstanding service and dedication in upholding the high standards of the Academy." The inaugural Medal of Commendation was given at the 50th Academy Awards, in April 1978, and is given irregularly.

Society of Motion Picture and Television Engineers

The Society of Motion Picture and Television Engineers (SMPTE) (, rarely ), founded in 1916 as the Society of Motion Picture Engineers or SMPE, is a global professional association, of engineers, technologists, and executives working in the media and entertainment industry. An internationally recognized standards organization, SMPTE has more than 800 Standards, Recommended Practices, and Engineering Guidelines for broadcast, filmmaking, digital cinema, audio recording, information technology (IT), and medical imaging. In addition to development and publication of technical standards documents, SMPTE publishes the SMPTE Motion Imaging Journal, provides networking opportunities for its members, produces academic conferences and exhibitions, and performs other industry-related functions.

SMPTE Membership is open to any individual or organization with interest in the subject matter.

SMPTE standards documents are copyrighted and may be purchased from the SMPTE website, or other distributors of technical standards. Standards documents may be purchased by the general public. Significant standards promulgated by SMPTE include:

All film and television transmission formats and media, including digital.

Physical interfaces for transmission of television signals and related data (such as SMPTE time code and the Serial Digital Interface) (SDI)

SMPTE color bars

Test card patterns and other diagnostic tools

The Material eXchange Format, or MXF

SMPTE ST 2110SMPTE's educational and professional development activities include technical presentations at regular meetings of its local Sections, annual and biennial conferences in the US and Australia and the SMPTE Motion Imaging Journal. The society sponsors many awards, the oldest of which are the SMPTE Progress Medal, the Samuel Warner Memorial Medal, and the David Sarnoff Medal. SMPTE also has a number of Student Chapters and sponsors scholarships for college students in the motion imaging disciplines.

SMPTE is a 501(c)3 non-profit charitable organization.
