    摘要： A software application for use on a portable communications device, such as a cellphone, personal digital assistant, personal computer, or other device capable of receiving user inputs and providing audio playback, allows users to select a track and add samples and effects to create a personal audio remix. The user may then share their creation with other users and friends via, for example, e-mail, social networking or specialized community sites for users of the application. Effects may be further generated using an internal accelerometer of the device. Samples and effects are stored with respect to the timing of the selected master track.

    摘要： When a PC connected to a mixer engine functions as an editing device to edit a configuration of signal processing in the mixer engine, components and wires included in the edited configuration of signal processing are displayed within a CAD screen on a display of the PC, and a delay amount occurring in processing corresponding to each of the components and wires when the mixer engine executes the signal processing is displayed in correspondence with each of the components and wires on the CAD screen. In this case, the delay amount corresponding to each wire is a value determined according to a result of assignment in which signal processing corresponding to each component is assigned to a plurality of signal processors in the mixer engine.

    摘要： A method and a system for providing sound generation instructions from a digitized input signal are provided. The invention comprises transforming at least part of the digitized input signal into a feature representation, extracting characteristic features of the obtained feature representation, comparing at least part of the extracted characteristic features against stored data representing a number of signal classes, selecting a signal class to represent the digitized input signal based on said comparison, and selecting from stored data, which represents a number of sound effects, sound effect data representing the selected signal class. Sound volume data is determined from stored reference volume data corresponding to the selected signal class and/or sound effect and from at least part of the obtained characteristic features, and sound generation instructions are generated based at least partly on the obtained sound effect data and the obtained sound volume data. It is preferred that the sound generation instructions are forwarded to a sound generating system, and that a sound output corresponding to the digitized input signal is generated by use of said sound generating system and the sound generation instructions. The transformation of the digitized input signal into a feature representation may include the use of Fourier transformation, and the extraction of the characteristic features may comprise an extraction method using spectrum analysis and/or cepstrum analysis. For each signal class there may be corresponding reference volume data.

    摘要： A musical instrument includes a fretboard, frets aligned in a first direction on the fretboard, a number of strings, aligned in a second direction above the frets, and tensioning devices operable to hold the strings in tension such that the pitch of adjacent strings at any given fret differ by one whole tone. Signals from string vibration pickups may be electronically processed and amplified to modify the sound produced by the musical instrument.

    摘要： A delay line circuit and method to delay digital data in a main memory is provided. The delay line circuit may comprise primary delay line cache, secondary delay line cache, and a cache controller to control communication of data between the secondary delay cache and the primary delay cache. The primary delay line cache may receive digital data to be delayed from a signal processor module, and secondary delay line cache may be connected to the primary delay line cache and the main memory to send data to and receive delayed data from the main memory. Data in the secondary delay line cache may be updated with data from the main memory or with data from the primary delay line cache. The invention extends to a machine-readable medium comprising a set of instructions for executing any of the methods described herein.
