Embodiment Construction

[0021] figure 1 It is the harmony synthesizer of the embodiment.

[0022] The harmony synthesizer 100 includes a decoding unit 101 , an alignment unit 102 , a MIDI unit 103 , a recalibration unit 104 and a speech synthesizer 105 .

[0023] The decoding unit 101 can be used to receive the input 114 of the main voice, so as to obtain the pitch track. The main sound input 114 may also refer to the input of a sound signal or the main sound input. The sound signal may be an analog signal.

[0024] In one embodiment, the decoding 111 of the pitch trace of the lead vocal input 114 is aligned with the lead vocal MIDI pitch trace 108 from the MIDI unit 103 .

[0025] The calibration data 106 is then used at the recalibration unit 104 to recalibrate the MIDI interval trace 116 obtained at 107 from the relationship between the MIDI lead voice 108 and the accompaniment trace 109 .

[0026] Thereafter, the recalibrated MIDI interval track 110 is synchronized with the decoding 117 of th...

Abstract

The invention describes a harmony synthesizer and a method for harmonizing vocal signals. The harmonizing method comprsies receiving an input vocal signal; identifying a pitch trace of the vocal signal; aligning the harmonization interval vector(s) to the pitch trace of the vocal input signal to form an aligned harmonization pitch trace; and synthesizing harmonization vocals according to the aligned harmonization pitch trace. The harmonizing method and the harmony synthesizer of the invention are suitable for singers without a good sense of rhythm yet do not sacrifice the quality of consonance.

Description

technical field [0001] The present invention relates generally to vocal harmonizers and methods for performing vocal harmonizers. Background technique [0002] The term "vocal harmony" may refer to a melodic line sung in harmony with a lead vocal. "Harmony" adds accompaniment to the main vocal that contains the main melody. In the present invention, the terms "harmony" and "accompaniment" are used interchangeably. [0003] The timbre of an unaccompanied lead melody can be dramatically enhanced by adding harmony correctly. Furthermore, the flaws exposed by an unaccompanied lead vocal can be transformed into a pleasing sonic character if accompaniment is added. For example, as an example, the harmonic phase discrepancy between the lead and accompaniment sounds is translated into perceptual amplitude and frequency differences of interest to the human ear. This is one of the reasons harmonies are so popular in commercial music production. However, unlike main melodies, voca...
