According to an embodiment, there is provided a system and method for automatically generating a complete music work from a partially completed work provided by a user. One approach uses an artificial intelligence (AI) engine that is trained by creating incomplete works from a database of complete works and then instructing the AI to complete the incomplete works. A comparison is made between the completed works and the originals to determine the effectiveness of the training process. After the AI is trained, it is applied to the user's incomplete work to produce a final music item.

The present invention provides a method for processing audio data, comprising the steps of providing a first audio track of mixed input data, said mixed input data representing an audio signal containing a plurality of different timbres, decomposing the mixed input data to obtain decomposed data representing an audio signal containing at least one, but not all, of the plurality of different timbres, providing a second audio track, analyzing audio data, including at least the decomposed data, to determine at least one mixing parameter, and generating an output track based on the at least one mixing parameter, said output track comprising first output data obtained from the first audio track and second output data obtained from the second audio track.

An apparatus for generating audio synchronized optical output is provided. The apparatus comprises an input channel to receive an input signal from an audio source and a controller. The controller is configured to receive the input signal from the input channel, analyze the input signal to determine one or more characteristics of the input signal. The apparatus associates the determined one or more characteristics of the input signal to one or more parameters of an optical output from an optical source and modulates the one or more parameters of the optical output in accordance with the one or more characteristics of the input signal. The system for generates real-time audio and/or performance synchronized optical outputs and enables connecting stage implements, musical instruments, lights, visual effects, lasers and other theatrical effects to be controllable by lighting data from human interactions with musical instruments or other stage or human interface devices.

A sound signal processor includes a memory storing instructions and a processor configured to implement the stored instructions to execute a plurality of tasks, the tasks including a sound signal input task configured to obtain a sound signal, a beat detection task configured to detect a beat in the sound signal, and a processing task configured to perform an effect processing on the sound signal in accordance with a timing of the detected beat.

Systems and methods for generating a playback-information display during time compression or expansion of an audio signal are provided. The system includes a processor that performs a method including displaying a first remaining playback-time associated with an audio file; adjusting the playback speed of the audio file during playback of the audio file; and, in response to the playback speed being adjusted, automatically displaying a second remaining playback-time associated with the audio file during playback of the audio file.

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 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 method of providing voice feedback to a listener as part of a user interface of a media playback system may include: storing multiple different voice feedback recordings in at least one computer-readable storage device, where each of the multiple different voice feedback recordings is of a different voice artist; receiving a listener command corresponding to a musical selection; determining an identifying musical characteristic of the musical selection; selecting a first voice feedback recording from the multiple different voice feedback recordings, where the first voice feedback recording corresponds to the identifying musical characteristic; and playing the first voice feedback recording to the listener via the media playback system.

An electronic device and a method for controlling the electronic device, the method including receiving an input of a command to reproduce music contents, determining audio characteristics information on the music contents and situation information on an environment where the music contents are being reproduced; and displaying a visualization effect of visualizing the music contents using the audio characteristics information and the situation information, and reproducing the music contents.
