Systems, devices, and methods for encoding digital representations of musical compositions are described. Various components of a musical composition that are defined in modern music theory, such as notes and bars, are encoded as respective hierarchically-dependent data objects in a data file. The hierarchically-dependent data objects encode the musical composition in a tree-like data structure with modular nodes and adjustable relationships between nodes. Note start times and beat start times are encoded independently of one another and characterized by a timing relationship that captures the expressiveness imbued when notes and beats are not precisely synchronized. Musical variations that preserve the timing relationship between the notes and beats of the original composition are also generated and encoded.

Gesture-controlled virtual reality systems and methods of controlling the same are disclosed herein. An example apparatus includes an on-body sensor to output first signals associated with at least one of movement of a body part of a user or a position of the body part relative to a virtual object and an off-body sensor to output second signals associated with at least one of the movement or the position relative to the virtual object. The apparatus also includes at least one processor to generate gesture data based on at least one of the first or second signals, generate position data based on at least one of the first or second signals, determine an intended action of the user relative to the virtual object based on the position data and the gesture data, and generate an output of the virtual object in response to the intended action.

A system and method for synchronizing an audio or MIDI file with a video file are provided. The method includes receiving a first audio or MIDI file, receiving a video file, and operating an audio synchronization module to perform steps of synchronizing the first audio or MIDI file with the video file, marking an event in the video file at a point on a timeline, detecting a first musical key for the event, retrieving a musical stinger or swell from a library, in which the musical stinger or swell is a second audio or MIDI file and is tagged with a second musical key, and the second musical key is relevant to the first musical key, and placing the musical stinger or swell at the point of the timeline marked for the event.

The disclosure is directed to a system to create a musical compilation utilizing multiple tools on a single pane-of-glass (screen). The system may include a text display module that may display text. The system may include an interactive portion located adjacent to the text display module. The interactive portion may include a playback module configured to output musical notes upon a first action onto a playback module interaction area. The interactive portion may include a recording module configured to record sounds upon a first action on a recording module interaction area. The interactive area may include a drafting module configured to allow modification of the text upon a first action on the drafting module interaction area. The playback module interaction area may be located adjacent to the recording module interaction area and the drafting module interaction area.

An automated music composition and generation system and process for producing one or more pieces of digital music, by providing a set of musical energy (ME) quality control parameters to an automated music composition and generation engine, applying certain of the selected musical energy quality control parameters as markers to specific spots along the timeline of a selected media object or event marker by the system user during a scoring process, and providing the selected set of musical energy quality control parameters to drive the automated music composition and generation engine to automatically compose and generate one or more pieces of digital music with control over the specified qualities of musical energy embodied in and expressed by the piece of digital music to composed and generated by the automated music composition and generation engine.

A system for creating an output comprises a processing unit, a user input module operably connected to the processing unit, and a video monitor operably connected to the processing unit. The processing unit provides on the video monitor: a grid image comprising multiple cells, each cell representing a duration of time; and a selection area comprising multiple select icons, each select icon representing a source data file. The processing unit is configured such that a user can create a grid layout representing the correlation between individual selected source data files and one or more of the multiple cells. The processing unit produces the output based on the correlation.

A system and method for generating an audio output file are provided. The method includes using one or more processors to perform steps of: receiving audio tracks, each audio track created according to audio parameters; separating each audio track into at least one selectable audio block, each audio block including audio content from a musical instrument involved in creating the audio track; assigning a unique identifier to each audio block; using the unique identifiers to select audio blocks, and generating the audio output by combining the audio blocks. The present invention prevents the use of the same combination of audio blocks in the generation of audio output to ensure that the audio output files generated a sufficiently unique. Also provided are audio file recording, editing and mixing modules enabling a user to have full creative control over mix and other parameters to modify as desired the audio file generated.

Gesture-controlled virtual reality systems and methods of controlling the same are disclosed herein. An example apparatus includes at least two of an on-body sensor, an off-body sensor, and an RF local triangulation system to detect at least one of a position or a movement of a body part of a user relative to a virtual instrument. The example apparatus includes a processor to generate an audio output of the virtual instrument in response to the at least one of the position or the movement.

A computer user interface (UI) is capable of generating a sound when a predetermined event occurs. The sound generated when the predetermined event occurs may possess at least some characteristics of a predominant natural language used by a user and/or a location of a computer implementing the UI. This enables the user to quickly assimilate the sound generated when the predetermined event occurs. Because the user quickly assimilates the sound generated when the predetermined event occurs, the user is able to rapidly respond to the predetermined event, at times using the computer UI, which reduces undesirable memory use, processor use and/or battery drain associated with a computing device that implements the computer UI.
