The present invention provides a method for processing music audio data, comprising the steps of providing input audio data representing a first piece of music containing a mixture of predetermined musical timbres, decomposing the input audio data to generate at least a first audio track representing a first musical timbre selected from the predetermined musical timbres, and a second audio track representing a second musical timbre selected from the predetermined musical timbres, applying a predetermined first audio effect to the first audio track, applying no audio effect or a predetermined second audio effect, which is different from the first audio effect, to the second audio track, and obtaining recombined audio data by recombining the first audio track with the second audio track.

A guitar amplifier and a control method of a guitar amplifier in which a setting of a performance mode can be easily changed without an interruption to a sound is provided. The guitar amplifier, which performs musical sound processing on an input musical sound and outputs it, includes a storage device which stores a plurality of information sets including a set value for each of one or two or more types of musical sound processing used in a performance mode, and a control device which changes the setting of the one or two or more types of musical sound processing to a setting according to a set value of a selected information set when information indicating ON of the performance mode, to which the selected information set from the plurality of information sets has been applied, is input.

The present invention provides a method for processing music audio data, comprising the steps of providing input audio data representing a first piece of music containing a mixture of predetermined musical timbres, decomposing the input audio data to generate at least a first audio track representing a first musical timbre selected from the predetermined musical timbres, and a second audio track representing a second musical timbre selected from the predetermined musical timbres, applying a predetermined first audio effect to the first audio track, applying no audio effect or a predetermined second audio effect, which is different from the first audio effect, to the second audio track, and obtaining recombined audio data by recombining the first audio track with the second audio track.

A music piece data comparison device includes: a music piece selector that allows a user to select music piece data; a first parameter generator that generates a first parameter from an entirety of the music piece data selected through the music piece selector; a first parameter transmitter that transmits the first parameter generated by the first parameter generator to a server being connected in a manner capable of communication; and a music piece analysis data receiver that receives matched music piece analysis data from the server, in which the server stores the music piece analysis data generated for the music piece data associated with a second parameter generated from the entirety of the music piece data and compares the second parameter with the first parameter to find the music piece analysis data whose second parameter matches the first parameter.

An audio information playback method includes reading audio information, reading separator information, acquiring note-on information and note-off information, moving a playback position, and starting playback. The starting of the playback is from the loop end position to the playback end position of an utterance unit subject to playback in response to acquisition of the note-off information corresponding to the note-on information.

The present invention provides a method for processing audio data, comprising the steps of providing a first audio track of mixed input data, said mixed input data representing an audio signal containing a plurality of different timbres, decomposing the mixed input data to obtain decomposed data representing an audio signal containing at least one, but not all, of the plurality of different timbres, providing a second audio track, analyzing audio data, including at least the decomposed data, to determine at least one mixing parameter, and generating an output track based on the at least one mixing parameter, said output track comprising first output data obtained from the first audio track and second output data obtained from the second audio track.

An adaptive music playback system is disclosed. The system includes a composition system that receives information corresponding to user activity levels. The composition system modifies the composition of a song in response to changes in user activity. The modifications are made according to a set of composition rules to facilitate smooth musical transitions.

An apparatus for decomposing an audio signal into a background component signal and a foreground component signal, has: a block generator for generating a time sequence of blocks of audio signal values; an audio signal analyzer for determining a characteristic of a current block of the audio signal and for determining a variability of the characteristic within a group of blocks having at least two blocks of the sequence of blocks; and a separator for separating the current block into a background portion and a foreground portion wherein the separator is configured to determine a separation threshold based on the variability and to separate the current block into the background component signal and the foreground component signal, when the characteristic of the current block is in a predetermined relation to the separation threshold.

A media-content augmentation system includes a processing system that receives input data in the form of temporally-varying events data. The processing system resolves the input into one or more categorized contextual themes, correlates the themes with metadata associated with at least one reference media file, and then splices or fades together selected parts of the media file, thus generating as an output, a media product in which transitions between its contextual themes are aligned with selected temporal events in the input data. The temporarily-varying events take the form of a beginning and an end in the case of a sustained feature, or a specific point in time for a hit point. A method aligns sections in digital media files with temporally-varying events data to compose a media product. The system augments a sensory experience of a user by dynamically changing and then playing selected media files within the context of the categorized themes input to the processing system.

For preceding and succeeding musical pieces, an extraction unit extracts audio signal of each of a centrally localized region and a non-centrally localized region, from L and R channel signals. A reproduction control unit makes the length of a first interval from start of fade-out to end of fade-in processing for the centrally localized region shorter than that of a second interval from start of fade-out to end of fade-in processing for the non-centrally localized region, and the reproduction control unit sets the first within the second interval. The reproduction control unit causes the fade-out processing for the non-centrally localized region to end after fade-in for the non-centrally localized region started, and performs cross-fade. The reproduction control unit causes fade-out processing pertaining to the centrally localized region to end after the fade-in processing pertaining to the centrally localized region has started, and causes cross-fader reproduction to be carried out.
