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.

Disclosed herein, among other things, are methods and apparatus for providing a time-stamp based controller for synchronization of sink or source sampling rate with external packet rate. A method for wireless communications includes receiving a transmission of a packet using a wireless transceiver of an electronic device, and using a processor of the electronic device to read a first value of a system timer and store the first value as an arrival time-stamp. The packet is decoded and processed by the processor, and sent to an output. When the processed packet is sent, a second value of the system timer is read, adjusted and stored as a departure time-stamp. The arrival time-stamp and the departure time-stamp are used to calculate an adjustment stimulus for a sample rate actuator of the electronic device. The sample rate actuator is configured to maintain synchronization of sampling rate with an external packet rate.

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.

A method and system for automatically generating a video stream synchronized with and reactive to an input audio stream uses one or more still or video images as a source of imagery. The system learns a latent representation of the source imagery and generates a visualization synchronized to, and reactive with, the input audio. A computer divides the audio stream into successive audio frames each characterized by a spectrogram. The computer generates a series of graphics of such latent representation according to the spectrogram of each audio frame. The computer pairs each audio frame with its corresponding graphic to generate an ordered series of graphics. The series of generated graphics can be displayed to accompany the audio in real-time or coupled with the audio stream to provide an audiovisual work that can be transmitted or digitally stored.

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.

The present invention provides a method for processing music audio data, comprising the steps of providing input audio data representing a first piece of music containing a mixture of predetermined musical timbres, decomposing the input audio data to generate at least a first audio track representing a first musical timbre selected from the predetermined musical timbres, and a second audio track representing a second musical timbre selected from the predetermined musical timbres, applying a predetermined first audio effect to the first audio track, applying no audio effect or a predetermined second audio effect, which is different from the first audio effect, to the second audio track, and obtaining recombined audio data by recombining the first audio track with the second audio track.

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.

The present invention relates to a method and apparatus to synchronise audio and video data. More particularly, the present invention relates to a loop-based audio-visual mixing apparatus and method for synchronising a plurality of videos and their corresponding audio streams to create audio-visual compositions. According to one aspect, there is provided a method for creating a synchronised lineal sequence from multiple inputs of audio and video data, comprising the steps of: providing a first input, comprising audio and video data; providing one or more subsequent inputs, comprising audio and video data; determining at least one rhythm metric unit for each input; queueing the or each subsequent inputs such that the or each subsequent input is triggered at a beginning of a next said rhythm metric unit of a determined input.

A guitar pedalboard for creating a loop includes a touch screen display for displaying a plurality of tracks of a loop. The touch screen display can be used to adjust a parameter of each track, and the loop. A plurality of footswitches corresponding to the plurality of tracks can be used to independently record and play each track of the loop.
