An environment awareness system includes a memory and first and second modules. The memory is configured to store environmental data, one or more music composition templates, and one or more maps, where the environmental data is indicative of at least one of a state, condition, or change in an environment in which the environment awareness system is located. The first module is configured to receive and store the environmental data in the memory. The second module is configured to: based on the one or more music composition templates and the one or more maps, convert the environmental data to a music signal including modifying variables in the one or more music composition templates based on the environmental data; and based on the music signal, play out a musical composition via an audio system to audibly indicate the at least one of the state, condition, or change in the environment.

Digital signal processing and machine learning techniques can be employed in a vocal capture and performance social network to computationally generate vocal pitch tracks from a collection of vocal performances captured against a common temporal baseline such as a backing track or an original performance by a popularizing artist. In this way, crowd-sourced pitch tracks may be generated and distributed for use in subsequent karaoke-style vocal audio captures or other applications. Large numbers of performances of a song can be used to generate a pitch track. Computationally determined pitch trackings from individual audio signal encodings of the crowd-sourced vocal performance set are aggregated and processed as an observation sequence of a trained Hidden Markov Model (HMM) or other statistical model to produce an output pitch track.

A display control method includes causing a display device to display a processing image in which a first image representing a note corresponding to a synthesized sound and a second image representing a sound effect are arranged in an area, in which a pitch axis and a time axis are set, in accordance with synthesis data that specify the synthesized sound generated by sound synthesis and the sound effect added to the synthesized sound.

An audio device and an electronic instrument are provided by which a device case can be downsized. An elastic member is interposed between an attachment hole provided in a panel-side sealed frame section of a speaker panel and a projection section of a speaker grill and, in this state, the speaker grill is fixed to the speaker panel by the projection section being subjected to torsion deformation. By the elastic member being deformed inside the attachment hole and coming in close contact with the surface of the projection section and the inner surface of the attachment hole, the attachment hole that is a through hole is filled. As a result of this structure, an attachment hole that is used when a speaker grill is attached to a speaker panel can be arranged at a position where it penetrates to an acoustic space.

A method for automating audio mashup production is disclosed. First, two or more audio files are received. Based on two or more audio files, two or more stem audio files and reference metadata associated with the two or more audio files are retrieved from a server. Each of the two or more stem audio files includes at least one of an instrument portion or a vocal portion that are included in the two or more audio files. After retrieval of the two or more stem audio files and the reference metadata, at least some musical parameters associated with segments of the two or more stem audio files are adjusted. Thereafter, the two or more stem audio files or adjusted segments of the two or more stem audio files can be combined into a single audio file. The single audio file is output to a user device.

A method for producing and streaming music generated from biofeedback. The method employs machine-readable language instructions that alter received signals from a wearable biofeedback device, generating musical tones to be played on a portable electronic device and/or shared with others. The varying musical tones that are produced by the method can be modulated by the user to reach a targeted state of emotion.

An electronic musical instrument in one aspect of the disclosure includes a keyboard, a processor and a memory that stores musical piece data that includes data of a vocal part, the vocal part including at least first and second notes together with associated first and second lyric parts that are to be successively played at the first and second timings, respectively, wherein if while a digitally synthesized first signing voice corresponding to the first note is being output, a user specifies, via keyboard, a third pitch that is different from the first and second notes prior to the arrival of the second timing, the at least one processor synthesizes a modified first singing voice having the third pitch in accordance with the data of the first lyric part, and causes the digitally synthesized modified first singing voice to be audibly output at the third timing.

A method is disclosed, the method comprising the steps of identifying a first real object in a mixed reality environment, the mixed reality environment having a user; identifying a second real object in the mixed reality environment; generating, in the mixed reality environment, a first virtual object corresponding to the second real object; identifying, in the mixed reality environment, a collision between the first real object and the first virtual object; determining a first attribute associated with the collision; determining, based on the first attribute, a first audio signal corresponding to the collision; and presenting to the user, via one or more speakers, the first audio signal.
