An external extended device, an audio processing method and an audio playback method are provided. The external extended device is configured to receive power supplied and a signal transmitted by a television device and the external extended device includes: an integrated physical interface connecting the external extended device and the television device; and a sound-mixing processing chip electrically connected with the integrated physical interface and configured to: acquire an accompaniment audio signal transmitted by the television device via the integrated physical interface; perform sound-mixing processing on a user voice signal gathered by a microphone device and the accompaniment audio signal; and transmit a sound-mixed signal to a power amplifier circuit of the television device via the integrated physical interface.

A new interface is provided that supports simultaneous transmission of an audio signal and a MIDI signal. Signals consecutive in predetermined units are transmitted to a reception side via a predetermined transmission path. The signals consecutive in the predetermined units include a signal of a first predetermined unit of the predetermined units including an audio signal and a signal of a second predetermined unit of the predetermined units including a MIDI signal. For example, the audio signal is a linear PCM signal constituting a stereo 2-channel audio signal. For example, the MIDI signal includes packet data of a predetermined length, and the packet data of the predetermined length is divided into a plurality of pieces, and transmitted by being included in signals of a plurality of pieces of the second predetermined units.

A method creates a virtual ensemble file by receiving, at a central assembler node, recorded performance files from a recording node(s). The recording nodes generate a respective one of the performance files concurrently with playing a backing track and/or nodal metronome signal. Each performance file includes audio and/or visual data. The assembler node generates the ensemble file as a digital output file. Another method creates the ensemble file by receiving input signals inclusive of the backing track and/or metronome signal at the recording node(s), and generating the performance files at the recording node(s) concurrently with playing the backing track and/or metronome signal. The performance files are transmitted to the assembler node. A computer-readable medium or media has instructions for creating the ensemble file, with execution causing a first node to generate the performance files, and a second node to receive the same and generate the ensemble file.

A retrofit cabling kit is suitable for use connecting an organ and a speaker, wherein the organ may be one of a Hammond brand, model B3 or C3 organ and the speaker may be one of a Leslie brand, model 122 or 147 speaker. The kit may include interfaces for attachment to each of the organ and the speaker and cables connecting the interfaces.

Various systems and methods are disclosed to allow users to conveniently control characteristics of sounds generated by musical instruments. Exemplary systems include a control unit in communication with any number of audio processing devices (APDs). The control unit may be operable to transmit control signals to each of the APDs, wherein the control signals include settings information relating to one or more APD processing parameter values. The control unit may be further operable to receive an audio signal generated by an instrument and transmit the same to the APDs. Accordingly, upon receiving the control signal and the audio signal from the control unit, the APDs may update their processing parameters based on relevant settings information contained in the control signal and process the audio signal into a processed audio signal, based on the updated processing parameters.

An external extended device, an audio processing method and an audio playback method are provided. The external extended device is configured to receive power supplied and a signal transmitted by a television device and the external extended device includes: an integrated physical interface connecting the external extended device and the television device; and a sound-mixing processing chip electrically connected with the integrated physical interface and configured to: acquire an accompaniment audio signal transmitted by the television device via the integrated physical interface; perform sound-mixing processing on a user voice signal gathered by a microphone device and the accompaniment audio signal; and transmit a sound-mixed signal to a power amplifier circuit of the television device via the integrated physical interface.

A pedal board assembly includes a pedal board having a pedal board surface structured and arranged to support at least one effect pedal, and a removable pedal switching system. The pedal board includes a receiving area structured and arranged to accommodate the pedal switching system.

A live distribution device includes an obtaining circuit, a data processing circuit, and a distribution circuit. The obtaining circuit is configured to obtain a piece of music and/or a user reaction to the piece of music. The user reaction is obtained from a viewing user, among a plurality of users, who is viewing a performance. The data processing circuit is configured to generate processed data based on the piece of music and/or the user reaction obtained by the obtaining circuit. The processed data indicates how the performance is viewed by the viewing user. The distribution circuit is configured to distribute the generated processed data to a terminal device of a non-viewing user, among the plurality of users, who is not viewing the performance.

A retrofit cabling kit is suitable for use connecting an organ and a speaker, wherein the organ may be one of a Hammond brand, model B3 or C3 organ and the speaker may be one of a Leslie brand, model 122 or 147 speaker. The kit may include interfaces for attachment to each of the organ and the speaker and cables connecting the interfaces.
