Abstract:
Disclosed is an audio signal processor that determines the type of audio processing to be performed utilizing an audio processing device (APD) and a removable module. The APD includes a digital signal processor (DSP) that modifies an input audio signal in accordance with a signal processing instruction set. The removable module includes the signal processing instruction set, and when the removable module is coupled to the APD, the signal processing instruction set is transferred to and implemented by the DSP of the APD to perform an audio processing function upon the input audio signal. The removable module may also include a user interface having at least one control to set a control parameter that is transferred to the DSP of the APD to further modify audio processing. The APD may also include a multi-state footswitch whose functionality can be determined by the DSP.
Abstract:
Disclosed is a security device coupled to a computing device, which is, in turn, coupled to a server through a computer network. The security device stores a serial number associated with the security device and a user key associated with the serial number. When the computing device attempts to log onto the server over the computer network, the server requests a serial number from the security device. If the serial number is stored within a user information database, the server obtains an associated user key and computes a challenge. Further, the server computes an expected response for the security device based on the associated user key. The server then sends the challenge to the security device over the computer network. If the server receives a response back from the security device that matches the expected response, the server will allow the computing device to log onto the server.
Abstract:
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.
Abstract:
Disclosed is a system and method to deliver a multimedia presentation of an audio file to a computing device for display to a user and further to allow the user to play a musical instrument in conjunction with the multimedia presentation. In response to a user selecting a musical piece at the computing device, a server transmits a session file associated with the musical piece to the computing device through a computer network. The session file includes an audio file and multimedia data such that the computing device can process the session file to present the multimedia presentation of the audio file to the user. An interface device is connected to the computing device and to the user's musical instrument. The interface device couples the musical instrument to the computing device such that the user can play the musical instrument in conjunction with the multimedia presentation of the audio file.
Abstract:
Multiple channels simultaneously provide multiple, modified digital audio signals, respectively, based on the same digital audio input signal. Each channel has a respective nonlinear effects section to apply a nonlinear transfer function, such as one that emulates a vacuum tube guitar amplifier, based on the input signal. In addition, a respective audio effects section is provided in each channel to apply an audio effect, such as a linear audio effect, based on the input signal. This audio effect is set in each channel by a controller. In another embodiment, multi-tracker (e.g., double tracker) functionality is provided by the multiple channels wherein at least one of the delay effect, pitch shift, and gain change in a channel is automatically changed as a function of the input signal.

Disclosed is a stringed instrument with embedded DSP modeling capabilities to model an acoustic stringed instrument. The stringed instrument has a body and a plurality of strings and each of the plurality of strings is respectively coupled to a pickup to detect a vibration signal for each string. An A/D converter converts the detected vibration signal of a string into a digital string vibration signal. A DSP is located within the body of the stringed instrument to process the digital string vibration signal and to implement an acoustic modeling system to process the digital string vibration signal in order to emulate a corresponding string tone of one of a plurality of selectable acoustic stringed instruments. Acoustic modeling includes acoustic string and body modeling, microphone placement modeling, and pick-sound modeling. The emulated acoustic digital tone signal is then converted to analog form for output to an amplification device.
