Microfreak/UG/19 Appendix B Vocoder/02 How It Works/02 Voice

• 19.2.2. The Perfect Modulator: Your Voice

  • A useful vocoder sound depends on pairing the modulator with a suitable carrier. Speak or sing with clear, even exaggerated articulation to drive the analysis filters.
  • Plosives such as “p,” “t,” and “b,” and sibilants such as “s,” “ch,” and “z,” can confuse the filter banks. The vocoder's high-pass filter helps remove them. Its hiss function can add high-frequency energy to help the filters respond.
