Apparatus and method for a celeste in an electronically-orbited speaker

摘要

Exemplary embodiments are directed to a sound modification system and loud speaker system. The system may impose amplitude, frequency and delay modulation on a signal representing the output of an musical instrument or other sound source while also imposing a sense of movement of the sound to the listener and a periodic variation of the harmonic content of the sound. Further, the system may simultaneously amplify sound signals without the amplitude, frequency, delay and spatial sense of modulation or a different sense of modulation. The system combines a plurality of sound transducers, a plurality of amplifiers and signal processors to provide a flexible, portable and practical sound modification and amplification system.

主权项

1. An apparatus for sound amplification and modification, comprising:
a plurality of sound transducers configured to direct sound in different directions; and a plurality of amplifiers operably coupled with the sound transducers; and an electronic signal processor operably coupled to the amplifiers; and the electronic signal processor configured to receive a sound signal, divide the sound signal into a plurality of sound signals, each of the plurality of sound signals occupying the same frequency band, modulate each divided sound signal with a separate amplitude envelope and couple each modulated sound signal to one or more of the amplifiers; and the electronic signal processor is further configured to modulate the divided sound signals in a manner that causes a sound source to orbit; and the electronic signal processor is further configured to delay at least a first signal of the divided sound signals such that the first sound signal coupled to at least a first transducer of the plurality of sound transducers facing in a first direction has a first delay, and an at least a second sound signal of the divided sound signals coupled to at least a second transducer facing in a second direction has a second delay; and the first delay and the second delay are different; and the first direction and the second direction are different; and the at least two delays are varied in a manner that causes a celeste effect.
