Abstract

PROBLEM TO BE SOLVED: To acquire and reproduce extremely natural sounds close to live sounds. SOLUTION: A sound source is considered as a set of many sounds, and information of sounds is subdivided and collected from all parts in accordance with the width and the shape of the sound source to faithfully acquire live natural sounds. On the basis of this conception, much more information emitted from the sound source is acquired by a sound collection device which is fundamentally comprised of an L-shaped sound collection plate consisting of two long and short plates and has a microphone at the inside corner between them or has many microphones arranged in one or plural arrays on the L-shaped sound collection plate.

Means for Solving the Problems In order to solve the above problems, taking a musical instrument as an example, when taking the sound of a guitar, a microphone is generally installed in front of the guitar.
The microphone is directly attached to the guitar, but when you pluck the strings of the guitar, the swing of the strings differs between the part where the strings are flipped and the neck, so in fact the head of the neck of the guitar The entire guitar is the sound source from to the end of the torso, and the same sound information is not output from the end to the end of the guitar, but slightly different sounds are emitted from all parts.

The instrument, whether a piano or a saxophone, is a resonance plate that amplifies the sound of the entire instrument, and is a sound source. The piano becomes a piano sound only after collecting information of a large number of sounds emitted from each part of the piano, and the violin becomes a violin sound only after collecting information of a large number of sounds emitted from each part of the violin.

In other words, the natural sounds we usually hear include many sound sources in a wide band, and each of the sound sources is not a single sound, but a sound source based on the width and size of the sound source. Various sounds are emitted from everywhere, and they reach your ears as a lump of sound.

Therefore, if the sound of the sound source is regarded as one sound, the original natural sound cannot be captured, and the sound source is considered as a group of many sounds. It is possible to faithfully capture raw natural sound by collecting the sound information in detail and collecting the sound.
