Sound Feature Positioner |
摘要 |
A music signal is supplied to a bandpass filter (15). The output of the filter is supplied to a first channel of a surround sound encoder (1) and the music signal is supplied to a second channel of the encoder. The encoded signal is supplied to a surround sound decoder (2) and then to an array of loudspeakers (3-6) for creating a soundfield (11) in a venue. The filter (15) extracts sufficient of the sound of, for example, a musical instrument and the encoder (1) allows the apparent location or direction of the extracted instrument to be placed and moved with respect to the soundfield (11).
