20100313740 | Stringed Instrument for Connection to a Computer to Implement DSP Modeling - Disclosed is a stringed instrument that includes a plurality of strings and a pickup to which each of the plurality of strings is respectively coupled that is connectable to a computer to implement DSP modeling. A serial interface circuit is coupled to the pickup and to a digital connector that formats each digital string vibration signal received from the pickup into a digital serial protocol. A computer is coupled by a serial link to the digital connector such that the computer receives each serially formatted digital string signal (SFDSS). The computer operates at least one audio DSP-based software module to process each received SFDSS wherein each SFDSS is processed in order to emulate a corresponding string tone of one of a plurality of stringed instruments to create an emulated digital string tone signal (EDSTS). Each EDSTS is then transmitted back over the serial link to the stringed instrument for playback. | 12-16-2010 |
20100022189 | System and Method for Real-Time Wireless Transmission of Digital Audio at Multiple Radio Frequencies - Disclosed is a system and method for the real-time wireless transmission of digital audio signals. A transmitter including a processor may be used to: generate a first digital data stream and a second digital data stream from a digital audio signal and transmit the first digital data stream at a first radio frequency and the second digital data stream at a second radio frequency. A receiver including a processor may be utilized to: receive the first and second digital data streams at the first and second radio frequencies, respectively, and generate the digital audio signal from the first and second digital data streams. | 01-28-2010 |
20100022183 | System and Method for Real-Time Wireless Transmission of Digital Audio Signal and Control Data - Disclosed is a system and method for the real-time wireless transmission of a digital audio signal and control data. A transmitter may be coupled to an audio source. The transmitter includes a processor to combine control data with a digital audio signal from the audio source and the processor wirelessly transmits the combined control data and digital audio signal to a receiver. The receiver includes a processor that is used to receive the combined control data and digital audio signal and to process the control data to perform a user pre-defined function. | 01-28-2010 |
20090086984 | Method and Apparatus for Reducing Noise in an Audio Signal - A technique for reducing inherent noise in a real time digital audio wireless system. The technique allows for low power stereo analog to digital and digital to analog converters to be used in a battery operated real time digital audio wireless applications. The audio signal is sent to the left and right channels of an analog to digital converter with a preceding audio amp of different gain at the input to each channel. The signals are simultaneously digitized then combined to generate a new digital value resulting in noise reduction at lower amplitudes. This new data word is then transmitted via radio waves to a digital audio receiver. Once the data is received it is output simultaneously to a stereo digital to analog converter. The digital to analog conversion of both left and right channels is then summed using a resistor network and an audio amplifier. The audio amplifier output is then reduced to create further reduction of noise at all amplitudes. | 04-02-2009 |
