Microfreak/UG/19 Appendix B Vocoder/07 Config
19.7. Vocoder Configuration
- The Vocoder settings can be adjusted as the voice or microphone changes. Global Utility settings affect every vocoder preset; settings under Utility > Preset are saved with the current preset.
- The global settings can be changed on the MicroFreak or in the MIDI Control Center.
Mic Settings
- Mic Gain: -12 dB to +59 dB, or Auto Gain (default).
- Noise Gate: Off or a threshold; default -70 dB.
- Mic Detection: Off or On (default).
19.7.1. Preset related Vocoder settings
- Two settings under Utility > Preset are saved with each preset:
- Vocoder Hiss Mode
- Vocoder Hiss Vol
- Older vocoders added high-frequency noise (“hiss”) to the lower, voiced “buzz” range to make consonants easier to understand.
Vocoder Hiss Mode
- Off: Only the lower, vowel-like buzz range is heard.
- Switched: A detector distinguishes voiced sections from unvoiced sections. During an unvoiced section, white noise replaces the carrier oscillator. Output is gated by the modulator and follows its level.
- Pass: The vocoded synth signal is mixed with the part of the microphone signal above 5 kHz, allowing the high frequencies of the voice through.
Vocoder Hiss Vol
- Sets the level of hiss mixed with the microphone signal and the white-noise replacement level in Switched mode, from -20 dB to 0 dB.
