The perceptual sound quality of desired audio signals (e. g. , human voice) captured by an electronic device (e. g. , cell phone) are improved by reducing ambient noise according to an algorithm that acts upon audio signals captured from a front and rear direction. More particularly, audio signals captured by two directional microphones pointing in opposite directions (e. g. , a front microphone which receives audio signals from a forward direction and a rear microphone which receives audio signals from a rear direction) are classified and subsequently enhanced (e. g. , unwanted signals are suppressed) according to a probability of their source (e. g. , front, rear, or noise) thereby providing an improved perceptual sound recording than each microphone individually. The resultant signals provide decreased noise since the contribution of the front and rear microphones are taken into consideration and the signal from the more relevant (e. g. , in the direction from which sound is coming) microphone is utilized.

Techniques for identifying encoded digital data in a multichannel hologram are described. A method can include steps of reading a first channel of a multichannel hologram, extracting first content data stored in the first channel, reading a second channel of the multichannel hologram, extracting second content data stored in the second channel, and utilizing the extracted content data. The extracted content data may be used for digital signature recognition. A system can include a multichannel hologram configured to store first, second, and third content data at first, second, and third channels respectively, at least one optical sensor configured to read the first, second, and third channels of the multichannel hologram and extract the first, second, and third content data, and a processor configured to measure an acceleration when the system is acted upon by a force.

An array loudspeaker includes a plurality of drivers arranged in an array configuration. A digital signal processor-based control system processes direct audio signal and indirect audio signal inputs for the loudspeaker to simultaneously produce direct sound in the form of a directed beam or wavefront, and indirect sound as a perceptually diffuse soundfield.
