摘要： An embodied music system. The system creates an interactive interface between a listener and the external environment. The system includes a physical device located in the environment that provides sensory input to the listener. An audio signal of the system is adapted to be heard by the listener. An encoder embeds inaudible control data into the audio signal. A decoder extracts the control data from the audio signal and transmits the control data to the physical device, thereby controlling operation of the device. Finally, an audio reproduction device is connected to the decoder and plays the audio signal for the listener. The embodied music system allows the listener to experience multi-sensory compositions.

摘要： Processor-implemented methods and systems for polyphonic note detection are disclosed. The method includes converting a portion of a polyphonic audio signal from a time domain to a frequency domain. The method includes detecting a fundamental frequency peak in the frequency domain. The method then detects a defined number of integer-interval harmonic partials. If a defined number of integer-interval harmonic partials relative to the fundamental frequency peak are detected the fundamental frequency is recorded as a detected note. This process is repeated for each fundamental frequency until each note in the polyphonic audio signal has been detected. For example, this method allows detection of each note in a strummed guitar chord to provide feedback on the tuning of each string in a strummed chord or allows detection and feedback of the timing and pitch errors for guitar chords played along with a reference track.

摘要： A system and method to assist a singer or other user. An audio source is processed to extract the lead vocals from the audio signal. This vocal signal is fed to a pitch detection processor which estimates the pitch at each moment in time. A user singing into a microphone provides a user vocal signal that is also pitch detected. The pitch of the lead vocal signal and the user vocal signal are compared and any difference is provided to a pitch shifting module, which then can correct the pitch of the user vocal signal. The corrected user vocal signal may be combined with a background signal comprising a signal from the audio source without the lead vocal signal, and then provided to headphones or loudspeakers to the user and/or an audience. This system and method may be used for Karaoke performances.

摘要： Audio data representative of a music piece is converted into data components in respective different frequency bands for every unit time interval to generate time frequency data pieces assigned to the respective different frequency bands. From the generated time frequency data pieces, detection is made as to each sustain region in which an effective data component in one of the frequency bands continues to occur during a reference time interval or longer. A feature quantity is calculated from at least one of (1) a number of the detected sustain regions and (2) magnitudes of the effective data components in the detected sustain regions. The music piece is classified in response to the calculated feature quantity.

摘要： A method, apparatus, and system (48) are disclosed for use in synthesizing an audio performance (50) in which one or more acoustic characteristics, such as acoustic space, microphone modeling and placement, can selectively be varied. In order to reduce processing time, the system utilizes pseudo-convolution processing techniques (54) at a greatly reduced processor load. The system is able to emulate the audio output in different acoustic spaces, separate musical sources (instruments and other sound sources) from musical context; interactively recombine (56) musical source and musical context with relatively accurate acoustical integrity, including surround sound contexts, emulate microphone models and microphone placement, create acoustic effects, such as reverberation (58), emulate instrument body resonance and interactively switch emulated instrument bodies on a given musical instrument.

摘要： A beat analysis module is described for determining beat information associated with an audio item. The beat analysis module uses an Expectation-Maximization (EM) approach to determine an average beat period, where correlation is performed over diverse representations of the audio item. The beat analysis module can determine the beat information in a relative short period of time. As such, the beat analysis module can perform its analysis together with another application task (such as a game application task) without disrupting the real time performance of that application task. In one application, a user may select his or her own audio items to be used in conjunction with the application task.
