Abstract

A sound system for capturing and reproducing sounds produced by a plurality of sound sources. The system comprises a device for receiving sounds produced by the plurality of sound sources and converting the separately received sounds to a plurality of separate audio signals without mixing the audio signals. The system may further comprise a device for separately storing the plurality of separate audio signals on a recording medium without mixing the audio signals and a device for reading the stored audio signals from the recording medium. A sound system and method for modeling a sound field generated by a sound source and creating a sound event based on the modeled sound field is also disclosed. The system and method captures a sound field over an enclosing surface, models the sound field and enables reproduction of the modeled sound field.

Dependent claims

A system for producing a holographic acoustical image of a sound event produced by a sound source, the system comprising:

at least one input node, wherein the at least one input node is configured such that a given one of the at least one input nodes is configured to individually capture parameters of the sound event with respect to a location that corresponds to the given input node;
an event related module configured to obtain information related to a position of the sound source during the sound event;
a source related module that includes information related to holographic acoustical dynamics of the sound source;
a plurality of output nodes,
wherein an amount of the output nodes included in the plurality of output nodes is greater than an amount of input nodes included in the at least one input node;
and
a processor configured to (i) apply the holographic acoustical dynamics of the sound source to the parameters of the sound event captured by the at least one input node and the information related to the position of the sound source obtained by the event related module of the sound event to generate the holographic acoustical image of the sound event, and (ii) to drive the plurality of output nodes to produce the generated holographic acoustical image.
