Sound field reproduction apparatus and sound field space reproduction system |
摘要 |
A sound field reproduction apparatus generates sound field synthesizing parameters according to a relative positional relationship between the listener and the sound source and performs frequency conversion on sound data according to the relative positional relationship. A convolutional operation is conducted on the sound data that are subjected to the frequency conversion and the generated sound field synthesizing parameters in order to synthesize the sound of the sound source of each channel. The synthesized sound is subjected to wave front synthesis for the synthesized sound by using n-channel sound sources to reproduce a sound field in a predetermined area.
