In the practice of sound recording and filmmaking, a lot of techniques have been accumulated for “sound stationing”, that is, spatial application of sound. One example is the technique of recording music by several microphones simultaneously.
To create a spatial sound picture, you can use sounds that differ not only in pitch, volume, and timbre but also have their own rhythm. Placing microphones in space in a certain way, the sound engineer can not only show a specific sound object with a close-up but also arbitrarily choose a “distribution angle” for any sound.
Something similar can be done with background noise. Unfortunately, this technique is rarely used in low-budget films, while in Hollywood blockbusters it is common practice. Great opportunities in creating spatial sound noise give stereo.
The most attractive side of the panoramic and widescreen cinema is the so-called presence effect. Stereo sound can play a leading role in creating this effect. The sound in the cinema can be played from various points in the cinema hall. Thus, it is possible to organize panning, for example, of the sound of a moving car, approach or attenuation in the space of thunderclaps.
Stereophony allows creating a unique shell of sounds around the viewer, creating both realistic and unprecedented fantastic sound atmosphere, and any sound perspective. But much more opportunities are provided by the modern 5.1 surround sound format.
On this page you can find several samples of musical-noise compositions made in 5.1 surround sound format.
