摘要： An adaptive audio system for a motor vehicle is disclosed. The audio system is operable to retrieve a music item from a storage device, classify the music item in a predefined music category the basis of a determined audio profile, select a category from a plurality of predefined music categories on the basis of a current driving behavior of the driver, and output a music item included in the selected category via an output device. The driving behavior of the driver is understood to mean the mode or style in which the driver drives.

摘要： A voice analysis method includes a variable extraction step of generating a time series of a relative pitch. The relative pitch is a difference between a pitch generated from music track data, which continuously fluctuates on a time axis, and a pitch of a reference voice. The music track data designate respective notes of a music track in time series. The reference voice is a voice obtained by singing the music track. The pitch of the reference voice is processed by an interpolation processing for a voiceless section from which no pitch is detected. The voice analysis method also includes a characteristics analysis step of generating singing characteristics data that define a model for expressing the time series of the relative pitch generated in the variable extraction step.

摘要： An advanced MIDI/audio processing system with virtual key-switches. The virtual key-switches are mapped to different musical concepts. As a user presses a key-switch in real time with the playing of musical notes, the musical concept mapped to the key-switch that was pressed is applied. The instrument then switches to a new playing state based on the particular musical concept that was applied. Furthermore, the system is configured to provide a smooth transition between dynamic levels when applying crescendo or diminuendo effects via a modulation wheel. The system also configured to provide enhanced cycling of alternate samples by providing an individual alternate cycle for each note of each articulation in each dynamic level. Furthermore, the system is configured to allow a user to store and recall specific cycle positions, and override an existing cycle to choose a specific alternate sample for a specific note.

摘要： Methods and devices to enable efficient beat-matched, DJ-style crossfading are provided. For example, such a method may involve determining beat locations of a first audio stream and a second audio stream and crossfading the first audio stream and the second audio stream such that the beat locations of the first audio stream are substantially aligned with the beat locations of the second audio stream. The beat locations of the first audio stream or the second audio stream may be determined based at least in part on an analysis of frequency data unpacked from one or more compressed audio files.

摘要： A “Concatenative Synthesizer” applies concatenative synthesis to create a musical output from a database of musical notes and an input musical score (such as a MIDI score or other computer readable musical score format). In various embodiments, the musical output is either a music score, or an analog or digital audio file. This musical output is constructed by evaluating the database of musical notes to identify sets of candidate notes for each note of the input musical score. An “optimal path” through candidate notes is identified by minimizing an overall cost function through the candidate notes relative to the input musical score. The musical output is then constructed by concatenating the selected candidate notes. In further embodiments, the database of musical notes is generated from any desired musical genre, performer, performance, or instrument. Furthermore, notes in the database may be modified to better fit notes of the input musical score.

摘要： Non-linear functions to be used for automatically varying current values of parameters to be set, independently of each other, are prepared in corresponding relation to a plurality of parameter setting operator members, such as faders of a mixer. In response to an automatic setting instruction, such as a scene recall instruction, the current value of the parameter, to be set via each of the operator members, is caused to vary gradually toward a given target value with a characteristic based on a corresponding one of the non-linear functions. For example, the non-linear function is defined by a start offset for setting a delay in a start of the variation, and a fade time necessary for actually causing the parameter to vary up to the target value after the variation start. Processing of a predetermined type of event (e.g., GPI event) may be delayed to allow for a time delay that would result during execution of automatic setting processing of each parameter.
