A method and system for playlist generation is disclosed. In one aspect, the system may include at least one analysis module for receiving and analyzing an unknown work and generating a corresponding representation thereof, and at least one identification (ID) server for receiving the representation from the analysis modules and determining the identity of the unknown work.

Playlist generation method and apparatus

A method and apparatus for creating a signature of a sampled work in real-time is disclosed herein. Unique signatures of an unknown audio work are created by segmenting a file into segments having predetermined segment and hop sizes. The signature then may be compared against reference signatures. One aspect may be characterized in that the hop size of the sampled work signature is less than the hop size of reference signatures. A method for identifying an unknown audio work is also disclosed.

Method and apparatus for creating a unique audio signature

A system that performs analysis and comparison of audio data files based upon the content of the data files is presented. The analysis of the audio data produces a set of numeric values (a feature vector) that can be used to classify and rank the similarity between individual audio files typically stored in a multimedia database or on the World Wide Web. The analysis also facilitates the description of user-defined classes of audio files, based on an analysis of a set of audio files that are members of a user-defined class. The system can find sounds within a longer sound, allowing an audio recording to be automatically segmented into a series of shorter audio segments.

A musical tone generating apparatus employs an array of microresonant structures to generate the harmonic component signals of a musical tone to be generated. The microresonant structures produce high frequency signals which are down converted to audio frequency range by mixing them with a high frequency reference signal. The desired tone color is achieved by modifying the relative amplitudes of the harmonic component signals to produce a desired tone color. A large number of microresonators are preferably integrated on a single integrated circuit substrate to provide a variable tone generating system in a relatively compact environment.

Musical tone generating apparatus employing microresonator array

A performance unit is provided that is freely movable within a three-dimensional performance region. Control circuitry is used to detect a position of the performance unit with respect to a reference point in the performance region and to generate a position signal. The position signal may be used as the basis either for generating a musical tone by an electronic musical instrument or for controlling a device that imparts an effect to, or otherwise controls a parameter of, a musical tone output from a musical instrument.

Position-based controller for electronic musical instrument

A microphone is provided with sensors to detect pitch and roll of the microphone and pressure applied to the microphone. The sensor signals are mapped by control circuitry to control desired effects such as reverberation, vibrato and tremolo to be applied to the audio signal from the microphone or to control effects or other parameters such as volume and tempo in an accompaniment musical instrument. Both the effect to be imparted and the degree of the effect can be controlled based upon signals from the sensors.

Sound parameter controller for use with a microphone

A method and apparatus for controlling electronic tone generation determines a type of gesture used by a player to contact a performance surface provided with an array of pressure sensors. The performance surface repeatedly is scanned to determine which of the sensors has been activated at each scan time. When a player contacts the performance surface, parameter data associated with the incoming gesture is compared with gesture recognition rules corresponding to various reference gestures. The gesture recognition rules may be preset, and/or the control system may be provided with an optional programming capability which allows the player to establish individualized gesture recognition rules in accordance with reference gestures input by the player. An electronic tone generator is controlled in accordance with the reference gesture which is determined to best fit an incoming gesture. Furthermore, the electronic tone generator may be controlled to generate a tone having a particular tone characteristic determined in accordance with a corresponding parameter of a particular gesture type such that a player may achieve a timbral variation simply by modifying the corresponding parameter of the particular reference gesture.

A polyphonic breath controlled electronic musical instrument includes a hand held breath sensor unit having a plurality of bidirectional air flow sensing passageways for detecting sucking or blowing action of the performer in a manner similar to a conventional acoustic harmonica. The breath sensor unit further includes pressure sensing transducers on the surface thereof, adapted to sense lip pressure and finger pressure of the performer, as well as a plurality of switches activated by the fingers of the performer holding the breath sensor unit. A microphone configured in the breath sensor unit picks up the vocal sounds of the performer. A thumb wheel controller is provided on the sensor unit to allow a control of tone parameters, such as volume, by the thumb of the performer. The signals from the sensors and switches on the sensor unit are provided to a remote electronic control unit which converts the analog sensor signals and on/off switch signals to MIDI control data in response to programs set by the performer. The performer may set various combinations of tone effects which may be varied in the performance by the performer activating the switches and pressure sensors. A tone generator receives the MIDI control signals and provides musical tones in response thereto. A conventional acoustic harmonica may be accurately emulated in addition to providing a number of other digital musical effects.
