Favis220c

Overview: For my 220C project, I am making vocoder renditions of choral music. The vocoder takes spectral qualities of the human voice and translates them to an instrument, creating what seems to be a "talking instrument" or "robot voice." Over the course of this project I aim to examine the effects of vibrato, pitch, vowels, and spectrum in the dry signal on the vocoded sound and discover how choral music translates to vocoded vocals.

I will be vocoding three choral pieces: Maurice Duruflé's "Ubi Caritas," Wolfgang Mozart's "Lacrimosa," and Eric Whitacre's "Lux Aurumque."

Vocoder: I made a basic vocoder in Max MSP, but I am not satisfied with the quality of sound and annunciation of vowels/consonants. Since the goal of the project is to examine the effect of dry parameters on the vocoded sound, the originality of the vocoder is not a priority to me. I may end up toying with an already-made vocoder in Logic for the purposes of efficiency, timbre, and sound quality.

Methodology: One singer is assigned to each voice for each song. Every song has bass, tenor, alto, and soprano lines, and some lines have multiple voices per line. The group will sing together during the recording sessions, but I each singer will have an individual microphone placed closely to his/her mouth to isolate his/her voice from the group. The goal is to allow singers to blend during the piece while still recording the voices separately for individual vocoding.

The following singers have generously agreed to record vocals for my project:

Ubi Caritas

Bass: Joel

Bass 2: ?

Tenor: ?

Tenor 2: Andrew Forsyth

Alto: Laura Austin

Soprano: Mia Farinelli

Lux Aurumque

Bass: Joel

Bass 2: Evan Gitterman?

Tenor: ?

Tenor 2: Andrew Forsyth

Alto: ?

Alto 2: Laura Austin

Soprano: ?

Soprano 2: Mia Farinelli

Lacrimosa

Bass: Joel

Tenor: Andrew

Alto: Laura Austin

Soprano: Grace Laboy

Voice Vocoding: I will go through each vocal track and play each part's appropriate notes on the keyboard vocoder. This may be difficult and tedious, but I can use MIDI in Logic to edit/split/move notes according to the rhythm of the individual voices. Choosing good reverb will also be essential for blending and authenticity.
