Ambisonics. Part one: General system description

Ambisonics is a technology for surround-sound which aims specifically at not making four (or any other number) of loudspeakers audible as separate sources of sound. It is designed using appropriate engineering methods and psychoacoustic theory that has shown good predictive value to make best use of available channels of communication (two or more ), and of loudspeakers (a limitation often forgotten), to give stable and uncoloured acoustic images in any position, keeping the physical means of reproducing the sound as unobtrusive as possible. It claims wide freedom of recording methods and of source material, as well as protection of recorded material from obsolescence.
