Voice Band Detection and Implementation

摘要

A system encourages experimentation with audio frequency and speaker technologies while causing an inanimate object to appear to lip-sync. The system applies a bandpass filter to an incoming audio stream to determine a magnitude of audio content in a frequency band of interest. For example, the system may filter results directed at the voice band, associated with speech. A controller controls a strobe light to flash at a particular point of travel of a platform reciprocating at a known frequency. An illusion is created that a sculpture, such as a piece of paper formed into a ring, is lip-synching to music.

主权项

1. A system comprising:
a strobe light; and a controller in communication with the strobe light, wherein the controller initiates sensing a magnitude of a voice band portion of an audio signal, wherein the controller causes the strobe light to flash in response to sensing the magnitude.
