We present a compendium of sounds and analyses that support a comprehensive approach to the musical use of the vocoder in automatic vocal tuning correction. Vocoder design has primarily focused on refining the vocoder as a realistic vocal transformer. However, its application within modern music emphasizes its unique sonic identity, adding distinctive coloration to the performer's voice. In this demo, we propose a benchmark that encompasses the vocoder's key elements. The vocoder is considered and analyzed as an audio effect playing an important role in vocal composition, in an approach similar to the study of musical instruments.
