An application for operating on a smart phone that records a musician's performance, either voice or instrumental, in combination with pre-recorded music. The combination allows for the auto tuning of the recording, the compression of the recording, the equalization of the recording, adding in reverb, correcting latency and the audio quantization of the rhythm, in addition to music enhancement features such as vocal spread, DeEsser, vocal doubler, vocal harmonizer, tape saturation, pitch correcdtion, flanger, phaser, auto pan, vibrato, tremolo, rotary, ring modulator, metalizer, expander, noise gate, wah, vocal leveling, tape stop, half speed, LoFi, and stutter. Once combined, the song is transmitted to social media and/or to an online store for sale. The user can also make a video with the song. Additional marketing such as song competitions or music reviews and ratings are also provided.

A singing scoring method and a singing scoring system based on streaming media are provided. In the singing scoring method and the singing scoring system, a first time difference between a moment at which a streaming video player starts to play a song and a moment at which an electronic device starts an audio recording program and a scoring engine is calculated. In addition, in the singing scoring method and the singing scoring system, a playing time difference of the streaming video player within every fixed period of a system time of the electronic device is continuously calculated, and the playing time difference is transferred to the scoring engine for accumulation to form a second time difference. The scoring engine then adjusts a singing time of each note in an entire musical score according to the first time difference and the second time difference.

Predetermined musical data for a song is received. The predetermined musical data includes chords and lyrics and rhythmic structures of the song. Audio data of a band generating music of the song is received. Generating real-time vocal audio that is in rhythm with the audio data and in harmony with the chords. The vocal audio includes the lyrics and is of a predetermined voice.

A sound generation device includes an electronic controller including at least one processor. The electronic controller is configured to execute a first acquisition module configured to acquire first lyrics data in which a plurality of characters to be vocalized are arranged in a time series and that include a first character and a second character that follows the first character, a second acquisition module configured to acquire a vocalization start instruction, and a control module configured to, in response to the acquiring of the vocalization start instruction, output an instruction to generate an audio signal based on a first vocalization corresponding to the first character, in response to the vocalization start instruction satisfying a first condition, and output an instruction to generate the audio signal based on a second vocalization corresponding to the second character, in response to the vocalization start instruction not satisfying the first condition.

In an electronic musical instrument that can output stored lyrics of a song in accordance with operations by a user, a processor determines whether a pedal is on or off, and if the pedal is off, the lyric is advanced in accordance with a user operation of a keyboard, and if the pedal is on, the lyric is not advanced in accordance with a user operation of a keyboard.

An electronic musical interface performs the following: displaying a chord function progression of a first segment of a musical piece that is to be played by a user in a first region of a display via identifiers specifying respective chord functions; playing back an automatic accompaniment of the first segment; receiving user performance data as the user plays the musical note input device along with the playback of the automatic accompaniment; analyzing each chord contained in the obtained user performance data to determine the chord function of each chord the user played; and displaying, in a second region of the display alongside the first region, an identifier that identifies the determined chord function of the chord the user plays so that the user can determine whether the chord function of each chord the user played matches the chord function of the chord displayed in the first region.

Disclosed are a system and a method for singing expression transplantation. A singing expression transplantation method performed by a singing expression transplantation system according to an embodiment may comprise the steps of: synchronizing each of a first sound source and a second sound source, which include different pieces of voice information with regard to an identical song; modifying the pitch of the first sound source on the basis of pitch information extracted from each of the first sound source and the second sound source, which have been synchronized; and extracting volume information from each of the first sound source and the second sound source and adjusting the magnitude of the volume regarding the first sound source, the pitch of which has been modified, according to each piece of extracted volume information.

An audio analysis method includes calculating, from an audio signal, a sound generation probability distribution which is a distribution of probabilities that sound representing the audio signal is generated at each position in a music piece, estimating, from the sound generation probability distribution, a sound generation position of the sound in the music piece, and calculating, from the sound generation probability distribution, an index of validity of the sound generation probability distribution.

The automatic performance device includes a storage part for storing a plurality of performance patterns, a performance part for playing a performance on the basis of a performance pattern stored in the storage part, an input part for inputting performance information through an input device that receives a performance operation of a user, and a selection part for selecting a performance pattern being a maximum likelihood estimation from the plurality of performance patterns stored in the storage part on the basis of the performance information input to the input part.

An electronic musical instrument having an accompaniment function which detects the sound volume of inputted melody sounds for each sound range, and controls the sound volume of accompaniment sounds for each sound range in accordance with the detected sound volume of the melody sounds for each sound range.
