The technique of binaural re-recording is simple but has not been well established. It follows the same principles of Worldizing, [ 10 ] a technique used by film sound designers in which sound is played over a loudspeaker in a real-world location and then re-recorded, taking along all the aspects and characteristics of the real-world ...
Surround microphone techniques largely depend on the setup used, therefore being biased towards the 5.1 surround setup, as this is the standard. [24] Surround recording techniques can be differentiated into those that use single arrays of microphones placed in close proximity, and those treating front and rear channels with separate arrays.
In the 1980s Richard Kaufman, Michael Gerzon and David Griesinger independently proposed three binaural recording techniques based on the Blumlein shuffling, but their ideas did not gain wide acceptance, either. [92] [100] In the 1990s researchers found that the Blumlein shuffling has a biomechanical analogue in the world of insects.
Engineers make a technical distinction between "binaural" and "stereophonic" recording. Of these, binaural recording is analogous to stereoscopic photography. In binaural recording, a pair of microphones is put inside a model of a human head that includes external ears and ear canals; each microphone is where the eardrum would be. The recording ...
The interaural signals (binaural ILD and ITD) at the ears are not the stereo microphone signals which are coming from the loudspeakers, and are called interchannel signals (Δ L and Δ t). These signals are normally not mixed. Loudspeaker signals are different from the sound arriving at the ear. See also Binaural recording.
Holophonics, like binaural recording, instead reproduces the interaural differences (arrival time and amplitude between the ears), as well as rudimentary head-related transfer functions (HRTF). These create the illusion that sounds produced in the membrane of a speaker emanate from specific directions.
It is a refinement of the baffled microphone technique for stereo initially described by Alan Blumlein in his 1931 patent on binaural sound. In the beginning Jecklin used omnidirectional microphones on either side of a 30 cm (1 ft.) disk about 2 cm (3/4") thick, which had a muffling layer of soft plastic foam or wool fleece on each side.
Blake is known for his use of binaural recording, an experimental recording technique which employs two microphones to create a 3-D stereophonic sound. [2] He has won a number of Grammy Awards, beginning with Best Engineered Album, Non-Classical and Best Rock Album for Sheryl Crow's The Globe Sessions (1998).
