An unmanned aerial vehicle (UAV) may emit masking sounds during operation of the UAV to mask other sounds generated by the UAV during operation. The UAV may be used to deliver items to a residence or other location associated with a customer. The UAV may emit sounds that mask the conventional sounds generated by the propellers and/or motors to cause the UAV to emit sounds that are pleasing to bystanders or do not annoy the bystanders. The UAV may emit sounds using speakers or other sound generating devices, such as fins, reeds, whistles, or other devices which may cause sound to be emitted from the UAV. Noise canceling algorithms may be used to cancel at least some of the conventional noise generated by operation of the UAV using inverted sounds, while additional sound may be emitted by the UAV, which may not be subject to noise cancellation.

Audiovisual reproduction system comprising a central unit managing a sound control circuit, and a telecommunications modem connected to a distribution network controlled by a host server, through a multitask operating system created around a tools and services library, characterized in that the operating system comprises a function that adjusts the sound control circuit to couple volumes in the various areas in which the loudspeakers in the audiovisual reproduction system are used, this function being accessible through a management mode of the multitask operating system, the coupling maintaining the ratios between the various volumes in each area when the volume in one area is modified.

Generative media content (e.g., generative audio) can be dynamically generated based on various inputs, which can include blockchain data. A playback device accesses blockchain data stored via a distributed ledger and generates media content based at least in part on the blockchain data. The playback device can access a library of pre-existing media segments and arrange a selection of pre-existing media segments from the library for playback according to a generative media content model and based at least in part on the blockchain data. The generated media content can then be played back via the playback device.

A system and method for operating and performing a remotely networked virtual musical instrument. A client transmits musical control data to a remote server over the network, encompassing a digital music engine and digitally sampled virtual musical instruments. In return, the client consumes, synchronizes, and mixes the combined server playback stream from the network of the fully expressive and interactive musical performance with zero audible latency.

A method is described comprising receiving a stem signal and an audio mix signal, wherein the audio mix signal comprises information of the stem signal. The method includes applying a first transform to the stem signal to provide a first stem spectrum, applying a second transform to the stem signal to provide a second stem spectrum, generating a plurality of mix signals using the audio mix signal, applying a first transform to each mix signal of the plurality of mix signals to provide a corresponding first mix signal spectrum, applying a second transform to each mix signal of the plurality of mix signals to provide a corresponding second mix signal spectrum, and using information of the first stem spectrum, the second stem spectrum, a first mix signal spectrum, or a second mix signal spectrum to detect the information of the stem signal in the audio mix signal.

Provided is a method of providing a melody recording based on a user humming melody in a user device. The method includes displaying a record button to be used to start recording of a humming melody of a user in response to an input of the user, and measuring a pitch of a sound that changes over time based on the humming melody of the user, and displaying a change in the pitch in real time. A region in which the change in the pitch is displayed includes at least a portion of a left region of a screen of the user device.

The present disclosure describes a process for clients in the music recording industry seeking to have audio recordings mixed to their specifications. This process involves enabling the client to designate which effects to include in their final audio mix in order to receive a finished audio track that sounds closer to the client's expectations. The client is empowered to specify exactly where audio effects should take place on a track-by-track basis. This process significantly improves the client's chances of receiving an audio mix from an engineer that meets the client's specifications, and helps the engineer create the audio mix right the first time.

Management device for a network of audiovisual information reproduction systems or jukeboxes, including a database with a plurality of sets of arrays, each array containing grouped information either about the composition of a jukebox, or the use of the jukebox, or the payment of fees. The database is managed by a computer server connected with the audiovisual information reproduction systems to receive messages sent by each audiovisual information reproduction device and containing information necessary to update determined sets of arrays in the database, and update data or the program for each audiovisual information reproduction device with information stored in at least one set of arrays in the database and transmitted in this message.

An image forming apparatus includes a controller. The controller includes a list display controller, a selection receiving section, a data request section, and an image formation controller. The list display controller acquires list data from a file server and causes display of the list data in the form of a list. The selection receiving section receives user selection of an article name from the list. The data request section requests image formation data corresponding to the article name that the user has selected from the file server. The image formation controller acquires image formation data and controls formation of an article image on a paper sheet based on the image formation data.
