A digital multi-media device provides features for a user unskilled in musical arts or sound handling techniques that provides automatic musical score composition in accordance with contained composition instructions. Stored sound samples and interfaces for obtaining external signals provide signals for merger with visual and sound presentations to obtain altered presentations either time shifted or in real time. In this fashion the user can create simulated radio stations for playback of prearranged and composed audio material. Further, the automatically composed musical score may be mixed with synthesized, digitized signals from the stored sound samples and external signals obtained through the device interfaces.

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 transition—achieved 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 timebase—between 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.

Methods and systems are described that are utilized for remotely controlling a musical instrument. A first digital record comprising musical instrument digital commands from a first electronic instrument for a first item of music is accessed. The first digital record is transmitted over a network using a network interface to a remote, second electronic instrument for playback to a first user. Optionally, video data is streamed to a display device of a user while the first digital record is played back by the second electronic instrument. A key change command is transmitted over the network using the network interface to the second electronic instrument to cause the second electronic instrument to playback the first digital record for the first item of music in accordance with the key change command. The key change command may be transmitted during the streaming of the video data.

Systems and methods for providing audio-file loop-playback functionality are provided. The system includes a processor that performs a method including setting a playback loop start-point based on a first selection of a button; setting a loop end-point, associating a loop with an audio file, and entering into the loop based on a second selection of the button; and exiting the loop based on a third selection of the button. Associating the loop with the audio file includes adding metadata to the audio file. The metadata associates the loop with a button. The method includes reentering the loop based on a fourth selection of the button and exiting the loop based on a fifth selection of the button.

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.

According to embodiments of the present disclosure, systems, methods, and computer program products for audio- and video-editing are provided. A reference file comprising a visual representation (e.g., musical score) of a final video/audio product is read and displayed to a user. A plurality of sections (e.g., measures) and a plurality of symbols (e.g., notes) are determined. A plurality of audio/video recordings are read where each recording corresponding to at least a portion of the visual representation. For each of the plurality of sections, a corresponding segment of at least one of the plurality of audio/video recordings is determined. First selections of a section of the plurality of sections are received from the user. For each of the first selections, a listing of the plurality of audio/video recordings in which at least a portion of the selected section occurs is displayed to the user. For each of the first selections, a second selection of an audio/video recording from the listing is received from the user thereby linking the selected section to the corresponding segment of the selected audio/video recording. An audio/video file is generated by combining each of the linked segments.

A human interface device including a processor coupled to a memory. A plurality of switch banks, also coupled to the processor and a rotary dial and a slider, both coupled to control circuitry, said control circuitry operable to provide positional information from the dial and the slider to the processor. The rotary dial and slider are disposed on the human interface device to form an association with the switch bank, a drive transducer coupled to said processor, said drive transducer including a plurality of LED sources spatially positioned on a positioning ring, a set of non-transitory processor instructions operable to direct the processor to provide MIDI commands through a BLE port.

According to an embodiment, there is provided a system and method for automatic AI-based song construction based on ideas of a user. In some embodiments, an embodiment is provided with a database that contains harmony templates which can be used by the user to augment the playback of a given music work. Various embodiments of the instant invention also benefit from a combination of expert knowledge resident in an expert engine which contains rules for musically correct song generation and machine learning in an AI-based audio loop selection engine for the selection of compatible audio loops from a database of audio loops.

Systems, devices, media, and methods are presented for playing audio sounds, such as music, on a portable electronic device using a digital color image of a note matrix on a map. A computer vision engine, in an example implementation, includes a mapping module, a color detection module, and a music playback module. The camera captures a color image of the map, including a marker and a note matrix. Based on the color image, the computer vision engine detects a token color value associated with each field. Each token color value is associated with a sound sample from a specific musical instrument. A global state map is stored in memory, including the token color value and location of each field in the note matrix. The music playback module, for each column, in order, plays the notes associated with one or more the rows, using the corresponding sound sample, according to the global state map.

Techniques are disclosed relating to implementing audio techniques for real-time audio generation. For example, a music generator system may generate new music content from playback music content based on different parameter representations of an audio signal. In some cases, an audio signal can be represented by both a graph of the signal (e.g., an audio signal graph) relative to time and a graph of the signal relative to beats (e.g., a signal graph). The signal graph is invariant to tempo, which allows for tempo invariant modification of audio parameters of the music content in addition to tempo variant modifications based on the audio signal graph.
