Abstract
The present invention is a system and method for processing and encoding audio information. An audio transducer receives audio information, preferably continuously, and converts the audio information into a signal representative of the audio information. A digital processing system receives the signal and electronically processes the audio signal. An optical processing system operatively couples with the digital processing system and performs a signal processing algorithm on the signal whereby the signal is encoded. The encoded signal is optimized for transmission over a very low bandwidth transmission channel. The encoded signal may be received and decoded with a system that may include a second optical processing and/or memory system.
Claims19
A system for processing and encoding audio information, comprising:
- an audio transducer for receiving audio information and converting the audio information into a signal representative of the of the audio information;
- a digital processing system for receiving the signal and for electronically processing the audio signal;
- and
- an optical processing system operatively coupled with said digital processing system for comparing the signal to a codebook of holographic image templates stored in the optical processing system to generate a codebook vector signal.
A system for processing and encoding audio information comprising:
- means for receiving audio information and converting the audio information into a signal representative of the audio information;
- means, operatively coupled to said audio information receiving means for electronically processing the audio signal;
- and
- means, operatively coupled with said electronic processing means, for performing an optical signal processing algorithm or function on the signal whereby the signal is holographically encoded into a codebook vector signal, the codebook vector signal being optimized for transmission over a lower bandwidth transmission channel.
A method for processing and encoding audio information for transmission over a lower bandwidth channel, comprising:
- receiving the audio information and transducing the audio information into a signal representative of the audio information;
- electronically processing the signal;
- optically processing the signal using a first optical processing system such that the signal is encoded by comparing the signal to a holographic image for optimal transmission over a lower bandwidth transmission channel;
- transmitting from a transceiver the encoded signal over a lower bandwidth transmission channel to a remote transceiver;
- receiving the encoded signal at the remote transceiver;
- and
- decoding the encoded signal by comparing the signal to a holographic image such that the audio information is obtained at a second optical processing system at the remote transceiver.
