# Sound Recipe - Vocoder & Pitched Vocal Textures

## Target

Synthetic, choral, and robotic vocal layers used as instruments and texture: vocoders, harmonized stacks, pitched/formant-shifted voices, and granular vocal beds. The electronic-art-pop signature of treating the human voice as a synth. Expensive through clean carrier design, tasteful tuning, and layered width.

These textures support the other recipes (Icy Electronic Art-Pop, ionnalee, DM). This page is the technical reference for *how* to build them.

The textures should feel:

- Synthetic but musical
- Choral or robotic by intent
- Wide and layered
- Cohesive with the synth world (shared tone)

Follows the house method: **intention → source → preset/plugin start → routing → settings → automation → taste checks.**

# Technique 1: Vocoder

## Intention

Robotic/synthetic vocal where a synth (carrier) is shaped by the voice (modulator). Classic electronic-pop move.

## Tools + setup

| Tool | ⭐ | Notes |
|---|---|---|
| Logic EVOC 20 PolySynth | 🟢⭐ | Built-in synth carrier + vocoder in one; easiest start |
| iZotope VocalSynth 2 (Vocoder module) | ⭐ | Flexible, modern, multiple modules |
| UAD Softube Vocoder | | Classic hardware-style color |

### EVOC 20 setup (fast path)

1. Put EVOC 20 PolySynth on a software-instrument track
2. Set **Side Chain** to your vocal track (the modulator)
3. Play chords on the instrument track (the carrier)
4. Start with a bright saw carrier; adjust **Formant** and **Bands** (more bands = more intelligible)
5. Blend **U/V Detection** so consonants come through

### Carrier design (the "expensive" part)

- Use a rich carrier: bright saws (Diva), wavetable (Pigments), or a pad — feed it as the carrier in VocalSynth, or use EVOC's internal synth
- The better the carrier, the more expensive the vocoder

## Insert chain (on vocoder output)

1. Pro-Q 4 — HPF ~150 Hz, presence for intelligibility 2–5 kHz
2. UAD Studio D Chorus / Eventide TriceraChorus — width
3. Reverb/delay send (shared with synths)

## Settings anchors

- **Mic for the modulator:** UT Twin87 (modern voicing) close, or an SM58 in an untreated room — clear consonants matter more than tone for vocoding
- Sing/speak clearly and rhythmically into the modulator
- Hold carrier chords slightly longer than the words for smear

## Automation

- Bring vocoder in for hooks/choruses; automate formant for movement

## Taste checks

- Intelligible enough to feel intentional. If muddy, fewer/clearer carrier notes + more bands.

# Technique 2: Harmonized Stacks

## Intention

Lush harmony clouds or tight robotic harmony — generated or pitched from one performance.

## Tools + setup

| Tool | ⭐ | Use |
|---|---|---|
| Eventide Quadravox | ⭐ | Up to 4 diatonic pitched voices; set key/scale, intervals |
| Eventide Octavox | ⭐ | 8 voices; huge harmony clouds, rhythmic offsets |
| Antares Harmony Engine | ⭐ | Musical generated harmony with formant control |
| iZotope VocalSynth 2 (Harmony) | | Quick harmony + character |
| Logic Vocal Transformer | 🟢 | Simple pitch/formant shifting |

### Quadravox/Octavox setup

1. Insert on the vocal (or a duplicate)
2. Set **Key** and **Scale** to the song
3. Choose intervals per voice (e.g., +3rd, +5th, +oct, −oct)
4. Add small **delay** offsets per voice for width/lushness
5. Pan voices across the field

## Insert chain (harmony bus)

1. Pro-Q — HPF ~150 Hz, thin low-mids (stacks get muddy)
2. Gentle bus comp (LA-2A) for cohesion
3. Reverb send (lusher than lead); MicroPitch for extra width

## Settings anchors

- Harmony bus lower and wider than lead; less presence
- For "clouds": detune/offset voices; for "robotic": tight, quantized, formant-shifted

## Automation

- Swell the harmony bus into choruses; mute in verses

## Taste checks

- Lead stays on top. Widen, don't just raise. Thin 200–500 Hz if the stack muds up.

# Technique 3: Pitched / Formant-Shifted Voices

## Intention

Gender-shifted, chipmunk/deep, or alien lead and accent voices (The Knife/Fever Ray signature).

## Tools + setup

- **Logic Vocal Transformer** 🟢 — pitch + formant separately (shift formant without pitch for gender morph)
- **Eventide H910 / H949** ⭐ — vintage harmonizer pitch/detune, gritty character
- **Eventide MicroPitch** — subtle detune doubling
- **Antares Throat / Mutator** — formant/throat reshaping, vocal mutation
- **Auto-Tune Pro** (Throat/Formant + hard retune) — hard-tuned alien lead

### Recipe for a gender-shifted lead

1. Duplicate the vocal
2. Vocal Transformer or H910: shift formant up/down (±several semitones), pitch to taste
3. Blend under or replace the lead for the effect
4. EQ to sit; send to shared space

## Settings anchors

- Subtle for "uncanny human"; extreme for overt robot/alien
- Keep one clean readable layer if the lyric matters

## Taste checks

- Decide: is this the lead (commit) or a texture (blend low)? Don't leave it half-in.

# Technique 4: Granular Vocal Beds (voice-as-pad)

## Intention

Turn a vocal into an evolving pad/atmosphere — choral wash made of your own voice.

## Tools + setup

- **Logic Alchemy / Sample Alchemy / Quick Sampler** ⭐ — load a sustained vocal note, granular-stretch into a pad
- **Eventide Crystals** — reverse + pitched vocal halos
- **Omnisphere** — granular-import a vocal sample
- **Spectral Gate / Ringshifter (Logic)** — spectral vocal textures

### Granular pad recipe

1. Bounce a held vowel (e.g., "ahh") across a few pitches
2. Load into Alchemy granular; set slow motion/spray
3. Pitch to chords; play as a pad
4. Heavy filter + reverb send; keep low in the mix

## Taste checks

- It's atmosphere — submerged and filtered, supporting the lead.

---

# Routing Summary

- **Vocoder/robot layers:** own tracks → shared synth reverb/delay (sit in the synth world, not the lead-vocal world)
- **Harmony bus:** lush reverb, wide, lower than lead; gentle glue
- **Granular beds:** heavy filter → big reverb send
- Keep the **clean lead** in its own (drier, central) space so processed layers don't blur the lyric

---

# Fast Path

- Robotic hook: EVOC 20, sidechain the vocal, bright carrier, chords
- Harmony lift: Quadravox in key (+3/+5/+oct), pan wide, lush reverb
- Alien accent: Vocal Transformer formant shift on a duplicate
- Vocal pad: Alchemy granular on a held vowel, filtered, reverb

---

# Adjustment Rules

**Vocoder unintelligible:** more bands, clearer carrier notes, raise U/V/consonant detection, presence EQ.

**Harmony muddy:** HPF + thin 200–500 Hz, widen instead of louder, fewer voices.

**Robot sounds cheap:** richer carrier (Diva/Pigments), add chorus/width, share the synth reverb.

**Texture blurs the lyric:** keep one clean central lead; move processed layers wider/quieter; automate them only where they help.

---

# Common Mistakes

- Thin/buzzy carrier (the #1 reason vocoders sound cheap)
- Harmony stacks too loud and too narrow
- Processed layers competing with the lead's lyric
- Wrong key/scale on harmonizers (sour notes)
- Using every technique at once

# Practical Summary

Treat the voice as a synth: design a rich carrier for vocoders (EVOC 20 / VocalSynth), build harmony clouds in-key with Quadravox/Octavox, create alien leads with formant shifting (Vocal Transformer / H910), and make pads from your own held vowels (Alchemy granular). Keep one clean central lead, place processed layers in the synth reverb world, and widen rather than over-loud. A good carrier and tasteful tuning are what separate expensive vocal-synth textures from cheap ones.
