A system and method for masking periodic noise, which may be capable of efficiently masking periodic noise by outputting music made by synthesizing a song and a beat sound. The system may include at least one sensor configured to detect a periodic noise signal, at least one memory configured to store at least one song and at least one beat sound, a speaker, and at least one processor configured to select a first song and a first beat sound from the at least one song and the at least one beat sound, adjust a tempo of the first song, determine a playing period of the first beat sound, and/or control the speaker to output music made by synthesizing the first song with the adjusted tempo and the first beat sound that may be repeated in accordance with the determined playing period.

Techniques are provided for generating an output file. One technique involves the steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; generating a harmonic chord map for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and generating the output file by combining the selected subset of content blocks and the input file. This technique may enable the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.

A musical sound processing apparatus, a musical sound processing method, and a storage medium capable of generating musical sound full of interest are provided. The musical sound processing apparatus includes a first control unit configured to control a timing of sounding of a first tone in steps that come with an interval therebetween and a second control unit configured to control a timing of sounding of a second tone following or overlapping the first tone according to a first tempo, wherein the first control unit is configured to control the timing of sounding of the first tone according to the first tempo when timing information has not been acquired from outside and control the timing of sounding of the first tone according to a second tempo which is based on the timing information and different from the first tempo when the timing information has been acquired.

A system is described that permits identified musical phrases or themes to be synchronized and linked into changing real-world events. The achieved synchronization includes a seamless musical transitionachieved using a timing offset, such as relative advancement of an significant musical onset, that is inserted to align with a pre-existing but identified music signature, beat or timebasebetween potentially disparate pre-identified musical phrases having different emotive themes defined by their respective time signatures, intensities, keys, musical rhythms and/or musical phrasing. The system operates to augment an overall sensory experience of a user in the real world by dynamically changing, re-ordering or repeating and then playing audio themes within the context of what is occurring in the surrounding physical environment, e.g. during different phases of a cardio workout in a step class the music rate and intensity increase during sprint periods and decrease during recovery periods.

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.

Disclosed are a system and a method for singing expression transplantation. A singing expression transplantation method performed by a singing expression transplantation system according to an embodiment may comprise the steps of: synchronizing each of a first sound source and a second sound source, which include different pieces of voice information with regard to an identical song; modifying the pitch of the first sound source on the basis of pitch information extracted from each of the first sound source and the second sound source, which have been synchronized; and extracting volume information from each of the first sound source and the second sound source and adjusting the magnitude of the volume regarding the first sound source, the pitch of which has been modified, according to each piece of extracted volume information.

A method for constructing an adaptive media file comprising a plurality of audio components configured to be used to form an audio output arranged to have a controllable tempo, the method comprising providing first audio data associated with a first audio component of the plurality of audio components, setting a playback tempo range of the first audio data, providing second audio data associated with the first audio component, setting a playback tempo range of the second audio data, wherein the tempo range of the second audio data is different to the tempo range of the first audio data, and associating the first audio data, the second audio data and the respective playback tempo ranges.

Due to discrepancies in musical timing signatures, the invention assesses whether a recorded displacement, expressed in terms of beats and fractions, between exit and entry points for a potential musical splice or cut, corresponds to permit a seamless music splicing of different musical sections. Assessment is achieved by establishing a third time base of pulses having a length dependent upon a lowest common multiple of fractions within respective bars for different sections, with the bars of the respective sections then partitioned into an equal number of fixed length pulses. A coefficient aligns different time signatures; it is a ratio between pulses within the different sections. The coefficient identifies corresponding locations of a cut point, related to a suitable anacrusis, in terms of respectively an aligned bar, beat, quaver and fraction in differing time signatures. The coefficient ensures that the time anacrusis in one time signature is interchangeable with others.
