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.

A data conversion system includes an acquisition unit, a conversion unit, and an output unit. The acquisition unit acquires first data. The conversion unit converts the first data into second data based on a conversion parameter to be determined by reference data related to a subject. The output unit outputs the second data.

A first device includes one or more processors and memory storing one or more programs configured to be executed by the one or more processors. The one or more programs include instructions for receiving, from a second device, audio mix information for a first audio item and receiving, from the second device, an indication that the first audio item is to be mixed with a second audio item distinct from the first audio item. In response to the indication, the one or more programs include instructions for transmitting to the second device an audio stream including the first audio item and the second audio item mixed in accordance with the audio mix information.

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.

Examples of wearable devices that can present to a user of the display device an audible or visual representation of an audio file comprising a plurality of stem tracks that represent different audio content of the audio file are described. Systems and methods are described that determine the pose of the user; generate, based on the pose of the user, an audio mix of at least one of the plurality of stem tracks of the audio file; generate, based on the pose of the user and the audio mix, a visualization of the audio mix; communicate an audio signal representative of the audio mix to the speaker; and communicate a visual signal representative of the visualization of the audio mix to the display.

Audio mix information is received from a plurality of users. Mix rules are determined from the audio mix information from the plurality of users, wherein the mix rules include a first mix rule associated with a first audio item. The first mix rule relates to an overlap of the first audio item with another audio item. The first mix rule is made available to one or more clients. After making the first mix rule available, an indication, from a respective client device, that the first audio item is to be mixed with a second audio item at the respective client device in accordance with the first mix rule is received. In response to the indication, a specification of the first mix rule is transmitted to the respective client device to be applied by the respective client device to generate a transition between the first audio item and the second item.

A computer-implemented method of digital music composition that creates a digital multi-genre musical composition track by downloading a host digital music track of a first genre and two or more separate donor multi-genre musical tracks, and then selectively modulating the instruments and rhythmic patterns of the donor musical tracks by manipulating the rhythmic patterns. The manipulation includes manipulating at least one of the intensities, frequency, sound, beat, and rhythm of the rhythmic pattern. The manipulated donor musical tracks are then integrated into the host musical track to create a combined digital multi-genre musical composition track, which can be downloaded, saved in a file, and replayed as needed.

A method comprises providing an audio file comprising two or more discrete tracks; separating the two or more discrete tracks; setting a limit on an amount at least one of the two or more discrete tracks may be altered; and outputting the separated and limited discrete tracks as a file for use by an end user.

A method for creating mash-ups of musical and/or other inputs includes parsing each input into a sequence of elements, which can be of equal length, beat-matching the inputs to make corresponding elements of equal beat length, and combining the elements to form a mash-up. Embodiments align the inputs before combination. The inputs can each include a plurality of tracks. Improved chaotic mapping can be used to substitute elements between tracks of the inputs. The elements, singly or in groups, can be modified before substitution. In other embodiments elements from the input tracks are introduced into a mash-up template whereby different combinations of corresponding elements are included in each mash-up frame. The tracks can be successively introduced into the mash-up and/or successively eliminated in a final Coda section of the mash-up. The combinations can be according to a recognizable pattern, which can be repeated, or determined by improved chaotic mapping.
