Microfreak/UG/19 Appendix B Vocoder/07 Config/01 Preset Settings
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.
