When a harmony function is on state, a generator determines a chord based on one or more notes of depressed keys in a chord kea area, automatically generates one or more additional notes having pitches which harmonizes the pitch of the note of the depressed key in a performance key area according to the determined chord, and inputs the “note of the pressed key in the performance key area+additional notes” to an assignment controller. The assignment controller assigns plural parts (timbres) to the inputted notes, and sounds the notes in timbres of the plural parts according to the assignment. That is, tone generation assignment process is performed regarding not only notes according to performance operation by a user but also automatically generated additional notes.

An electronic device and a method for controlling the electronic device are provided. The method includes receiving at least one input sound from a user, determining one of a plurality of reference sounds included in a guide track as a device playing sound corresponding to the at least one input sound, and playing the device playing sound.

Various embodiments provide techniques for generating real-time musical accompaniment for musical content included in an audio signal. A real-time musical accompaniment system receives the audio signal via an audio input device. The system extract, from the audio signal, musical information characterizing at least a portion of the musical content. The system generates musical information that has at least one of a rhythmic relationship and a harmonic relationship with the musical information. The system generates an output audio signal that is complementary to the musical information. The system transmits, substantially immediately after receiving the audio signal, the output audio signal to an audio output device.

A multifunctional microphone, includes a controlling mainboard; a sound collector electrically connected with the controlling mainboard; a speaker electrically connected with the controlling mainboard; and a sound adjusting module arranged on the controlling mainboard and configured to adjust sound collected by the sound collector.

Disclosed herein are method, system, and computer program product embodiments for performing the continuous tuning of received audio input from an earpiece or microphone especially customized for karaoke singing, wherein the audio input may be mixed with user-selected song input, and the joint mixed input is independently altered in the frequency domain for output to an earpiece worn by a user as well as separately for an additional audio output to an external connected speaker, for an optimal karaoke experience.

User interface techniques provide user vocalists with mechanisms for seeding subsequent performances by other users (e.g., joiners). A seed may be a full-length seed spanning much or all of a pre-existing audio (or audiovisual) work and mixing, to seed further contributions of one or more joiners, a user's captured media content for at least some portions of the audio (or audiovisual) work. A short seed may span less than all (and in some cases, much less than all) of the audio (or audiovisual) work. For example, a verse, chorus, refrain, hook or other limited “chunk” of an audio (or audiovisual) work may constitute a seed. A seeding user's call invites other users to join the full-length or short-form seed by singing along, singing a particular vocal part or musical section, singing harmony or other duet part, rapping, talking, clapping, recording video, adding a video clip from camera roll, etc. The resulting group performance, whether full-length or just a chunk, may be posted, livestreamed, or otherwise disseminated in a social network.

The present invention aims to change contents of an automatic accompaniment in accordance with a pitch range of a key that a user plays. The electronic musical instrument includes operated keys and a processor. The processor acquires the number of operated keys for each pitch range in accordance with the operation of the keyboard and instructs to switch an automatic accompaniment pattern accompaniment sounds to be emitted in accordance with the acquired number of operated keys for each pitch range.

The present disclosure relates to a method and an apparatus for determining a karaoke singing score, and belongs to the technical field of karaoke singing systems. The method includes: capturing a singing audio by an audio capture device upon detection of a karaoke singing instruction to a target song; acquiring a plurality of time units obtained by dividing a preset voice period of the target song; for each time unit, performing time offset adjustment on the time unit based on a preset adjustment duration to obtain at least one offset time unit, determining pitch values corresponding to the time unit and each time offset unit respectively in the captured singing audio, scoring each of the determined pitch values based on a preset reference pitch value of the time unit, and determining the highest score as a score corresponding to the time unit; and determining a total score of the singing audio based on the score corresponding to each time unit. The method and the apparatus have the advantage that scoring accuracy of the singing audio is improved.

An electronic device according to an embodiment of the present disclosure includes at least one memory configured to store executable instructions, and a processor configured to execute the executable instructions stored in the at least one memory to cause the electronic device to acquire a first sound signal from an external source, generate a musical sound signal according to a performance operation, output the first sound signal and the musical sound signal to a first output destination, and output the musical sound signal to a second output destination different from the first output destination.

A method for determining volume adjustment ratio information comprises acquiring a first singing audio and an original accompaniment audio corresponding to the first singing audio, wherein the first singing audio is a user singing audio; acquiring a first audio of a non-singing part in the first singing audio, and acquiring a loudness characteristic of the first audio; acquiring, in the original accompaniment audio, a second audio whose playback duration corresponds to a playback duration of the first audio, and acquiring a loudness characteristic of the second audio; and determining a ratio of the loudness characteristic of the first audio to the loudness characteristic of the second audio as adjustment ratio information for adjusting an accompaniment volume of the first singing audio.
