GRACIDA OLVERA, Gisela e ORDUNA BUSTAMANTE, Felipe. Evocanto: Computer Program for Analyzing the Singing Voice using Digital Signal Processing. Comp. y Sist. [online]. 2011, vol.15, n.1, pp. 39-50. ISSN 1405-5546.
The article presents the development of a computer program, with a friendly user interface, intended as a didactic tool for the study and teaching of the singing voice and vocal technique. The program captures the acoustic signal with a microphone and a digital audio interface, spectral analysis is performed and acoustic descriptors of tuning, vibrato and resonance of the singing voice are calculated. The program displays the spectral analysis and other parameters, allowing for an objective evaluation. Real-time interaction allows users immediate feedback of the effects of their own vocal technique on the acoustic singing voice signal; this, in addition to technical and musical indications provided by the singing teacher.
