A method for detecting audio signal beat points of a bass drum, and a terminal. The method comprises: acquiring several intrinsic mode functions based on an inputted audio signal to be detected; calculating instantaneous signals, wherein the instantaneous signals includes instantaneous strength signals and instantaneous frequency signals corresponding to the several intrinsic mode functions; acquiring characteristic signals of the bass drum based on the instantaneous strength signals and the instantaneous frequency signals corresponding to the several intrinsic mode functions; performing peak detection on the characteristic signals to acquire a plurality of peak points; and acquiring the beat points of the bass drum based on the plurality of peak points.

A system for identifying the contribution of a given sound source to a composite audio track, the system comprising an audio input unit operable to receive an input composite audio track comprising two or more sound sources, including the given sound source, an audio generation unit operable to generate, using a model of a sound source, an approximation of the contribution of the given sound source to the composite audio track, an audio comparison unit operable to compare the generated audio to at least a portion of the composite audio track to determine whether the generated audio provides an approximation of the composite audio track that meets a threshold degree of similarity, and an audio identification unit operable to identify, when the threshold is met, the generated audio as a suitable representation of the contribution of the sound source to the composite audio track.

A system for generating audio content in dependence upon an input audio track comprising audio corresponding to one or more sound sources, the system comprising an audio input unit operable to input the input audio track to one or more models, each representing one or more of the sound sources, and an audio generation unit operable to generate, using the one or more models, one or more audio tracks each comprising a representation of the audio contribution of the corresponding sound sources of the input audio track, wherein the generated audio tracks comprise one or more variations relative to the corresponding portion of the input audio track.

A resonance sound signal generation device comprises a designation receiver that receives designation of a pitch, a sound signal instructor that provides an instruction for generating a sound signal corresponding to the designated pitch, a producer that produces a resonance sound signal representing a resonance sound based on a plurality of pitches, a determiner that determines whether another pitch is designated at a time of designation of one pitch, and a resonance sound instructor that instructs the producer to produce a resonance sound signal of the one pitch and a resonance sound signal of the another pitch based on the one pitch and the another pitch when determination is made that the another pitch is designated at the time of designation of the one pitch, and does not instruct the producer to produce resonance sound signals when determination is made that the another pitch is not designated at the time of designation of the one pitch.

For example, provided is an information processing device with which the entire performance can be felt really visually. The information processing device TB according to the present invention includes a processor performing a reception process of receiving input of performance information including pitch information, a first image output process of outputting a first image according to the received performance information, a performance determination process of determining at least any of tonality, a chord type, and a pitch name on the basis of the received performance information, and second image output process of outputting a second image according to a result determined in the performance determination process.

A dual sound source audio data processing method and apparatus are provided. The method includes obtaining audio data of a song pair including a first song and a second song, the first and second songs having a same accompaniment audio but different voice audio. The audio data is decoded to obtain first mono audio data corresponding to the first song and second mono audio data corresponding to the second song. The first and second mono audio data are combined to one piece of two-channel audio data including a left audio channel and a right audio channel. A play time of the two-channel audio data is divided into play periods, and energy suppression is selectively performed on the left audio channel and the right audio channel in different play periods.

Methods and systems are disclosed to facilitate creating the sensation of vibrotactile movement on the body of a user. Vibratory motors are used to generate a haptic language for music or other stimuli that is integrated into wearable technology. The disclosed system in certain embodiments enables the creation of a family of devices that allow people such as those with hearing impairments to experience sounds such as music or other input to the system. For example, a sound vest or other wearable array transforms musical input to haptic signals so that users can experience their favorite music in a unique way, and can also recognize auditory or other cues in the user's real or virtual reality environment and convey this information to the user using haptic signals.

A lyrics analyzer generates tags and explicitness indicators for a set of tracks. These tags may indicate the genre, mood, occasion, or other features of each track. The lyrics analyzer does so by generating an n-dimensional vector relating to a set of topics extracted from the lyrics and then using those vectors to train a classifier to determine whether each tag applies to each track. The lyrics analyzer may also generate playlists for a user based on a single seed song by comparing the lyrics vector or the lyrics and acoustics vectors of the seed song to other songs to select songs that closely match the seed song. Such a playlist generator may also take into account the tags generated for each track.

The teachings described herein are generally directed to a system, method, and apparatus for separating and mixing tracks within music. The system can have a video that is synchronized with the variations in the musical tempo through a variable timing reference track designed and provided for a user of the preselected performance that was prerecorded, wherein the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the preselected performance.

Systems and methods for mapping parts in a digital sheet music file for a harmony. The method may include receiving a selection of a music segment for part mapping, receiving a digital sheet music representation of the selected music segment, and determining a plurality of plausible part mapping for the digital sheet music representation. A part mapping identifies one or more distinct musical parts in the digital sheet music representation, each of said one or more distinct musical parts corresponding to a performer of the harmony. The method may also include analyzing one or more features of the plurality of plausible part mapping to identify a highest probability part mapping based on previously stored information, and outputting the highest probability part mapping.
