A harmony generation device and a program for the same which can generate a natural harmony sound are provided. The harmony generation device (1) generates first and second harmony tones to which a voice input through a microphone (M) is shifted in pitch by first and second shift amounts calculated based on both the voice input through the microphone (M) and a chord determined from performance information of an electric guitar (G) input through an input device (34). That is, since the first and second harmony tones can be tones based on the chord of the electric guitar (G) that changes from moment to moment, the harmony sound obtained by mixing the first and second harmony tones with the voice input through the microphone (M) can be a natural harmony sound that is rich in variation according to the chord of the electric guitar (G).

An accessory for modifying sound output of a musical instrument. The body of the instrument has a soundboard. The accessory includes a sound sensor, an actuator, a fastener, and a controller. The sound sensor engages the body and senses vibration of the body representing the sound output of the musical instrument. The actuator engages the soundboard and deforms the soundboard of the musical instrument so as to modify the sound output of the musical instrument. The sound sensor is preferably arranged distally to the actuator. The fastener engages the accessory to the musical instrument, to locate the actuator against the soundboard of the musical instrument. The controller is connected to the actuator and the sound sensor for receiving and analysing the sound output sensed by the sound sensor, and controlling the actuator in dependence on the sound output sensed by the sound sensor.

Techniques have been developed to facilitate (1) the capture and pitch correction of vocal performances on handheld or other portable computing devices and (2) the mixing of such pitch-corrected vocal performances with backing tracks for audible rendering on targets that include such portable computing devices and as well as desktops, workstations, gaming stations, even telephony targets. Implementations of the described techniques employ signal processing techniques and allocations of system functionality that are suitable given the generally limited capabilities of such handheld or portable computing devices and that facilitate efficient encoding and communication of the pitch-corrected vocal performances (or precursors or derivatives thereof) via wireless and/or wired bandwidth-limited networks for rendering on portable computing devices or other targets.

Vocal musical performances may be captured and continuously pitch-corrected at a mobile device for mixing and rendering with backing tracks in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured in the context of a karaoke-style presentation of lyrics in correspondence with audible renderings of a backing track. Such performances can be pitch-corrected in real-time at the mobile device in accord with pitch correction settings. In some cases, such pitch correction settings code a particular key or scale for the vocal performance or for portions thereof. In some cases, pitch correction settings include a score-coded melody sequence of note targets supplied with, or for association with, the lyrics and/or backing track. In some cases, pitch correction settings are dynamically variable based on gestures captured at a user interface.

The present disclosure provides an audio data processing method performed at an electronic apparatus, the method including: obtaining a corresponding lyric file according to audio data to be processed; dividing the audio data according to a sentence in the lyric file to obtain an audio data segment; extracting data corresponding to an end syllable in the audio data segment; and performing harmonic processing on the data corresponding to the end syllable. In addition, further provided is an audio data processing device matching the method. The audio data processing method and device can prevent entire audio data from being attached with a harmonic sound effect during an entire time period, thereby improving authenticity of harmonic simulation.

A method for processing a voice signal by an electronic system to create a song is disclosed. The method comprises the steps in the electronic system of acquiring an input singing voice recording (11); estimating a musical key (15b) and a Tempo (15a) from the singing voice recording (11); defining a tuning control (16) and a timing control (17) able to align the singing voice recording (11) with the estimated musical key (15b) and Tempo (15a); applying the tuning control (16) and the timing control (17) to the singing voice recording (11) so that an aligned voice recording (20) is obtained. Next, the method comprises the step of generating an music accompaniment (23) as function of the estimated musical key (15b) and Tempo (15a) and an arrangement database (22) and mixing the aligned voice recording (20) and the music accompaniment (23) to obtain the song (12). A system a server and a device are also disclosed.

An electronic musical instrument including a musical instrument body which is supported by first finger of a hand of an instrument player and at least one finger other than the first finger, scale keys which are provided at positions that are contacted with fingers other than the first finger on one surface of the musical instrument body, and each of which specifies a scale of a musical sound, a touchpad which is provided in an area that is contacted with the first finger on an other surface of the musical instrument body, and includes a sensor that has a planar detection area for detecting a contact position of the first finger, and a processor which controls emission of the musical sound whose scale has been specified by the scale key in accordance with the contact position of the first finger detected by the touchpad.

An acoustic guitar is provided that includes a neck and a body. The acoustic guitar also includes a user interface module including an audio effect module configured to implement one or more audio effects, and one or more effect controllers, with each effect controller being configured to set a level of a corresponding audio effect implemented by the audio effect module. The user interface module further includes at least one input blend controller and a voice controller configured to allow a user to select a patch from a plurality of available patches, with each patch of the plurality of available patches comprising a configuration of one or more audio effects set at various levels to arrive at a desired effect template.

A method and a device provides a user with the ability to freely improvise or play around with a selection of different chords and be provided with visual guidance assisting the improvisation of melody, while also providing accompaniment consistent with the selection of chords. Sound files consistent with a user selection of a chord and/or a dynamic level are selected from an audio library and played, while the user is given visual cues on a user interface keyboard assisting the user to select notes that are consistent with the chord selected for the accompaniment.
