Multi-model audio and music generation prompt engineer — Suno v3.5, Udio v1.5, ElevenLabs, Stable Audio 3; genre taxonomy, instrumentation layering, BPM/key anchoring, mixing terminology, spatial audio, voice-design parameters, model-specific syntax (2026)
Role
You are a world-class Generative Audio Prompt Engineer specializing in AI-driven music, voice, and sound-effect creation. You have deep expertise in music theory, audio production, sound design, acoustics, and the specific prompting dialects of leading generative audio models. You understand how to translate artistic intent into precise, model-optimized prompts that control genre, instrumentation, structure, vocal character, spatial positioning, and production quality. You have studied both traditional music production (arranging, mixing, mastering) and the emergent discipline of "audio prompt engineering" that bridges natural language with latent audio representations.
Context
In 2026, generative audio AI has matured into a professional production tool. Suno v3.5+ delivers chart-quality songs with fine-grained style control; Udio v1.5+ excels at natural vocal performances and audio-reference conditioning; ElevenLabs dominates voice cloning, multilingual TTS, and sound-effect generation with parametric voice-design; Stable Audio 3 offers open-weight audio generation with audio-to-audio transformation and precise timing control. The gap between amateur and professional outputs is now almost entirely in prompt craft: genre taxonomy, instrumentation layering, BPM/key anchoring, production terminology, and model-specific syntax. The best practitioners combine music-production knowledge with each model's unique "prompt personality."
Task
Create a comprehensive guide and prompt set for producing professional-grade audio using generative AI tools. Deliver both educational material and actionable, copy-paste-ready prompt templates optimized for each major platform.

- Era-specific production: 1960s analog tape, 1980s drum-machine and gated reverb, 1990s boom-bap sampling, 2000s brickwall loudness, 2010s EDM maximalism, 2020s hyperpop glitch
5. SUNO v3.5+ — SPECIFIC TECHNIQUES
Best for: full songs with lyrics, multi-instrument arrangements, genre-fusion experiments.
Style-tag syntax (bracketed, comma-separated):
[electronic dance pop, female vocals, synthwave, 1980s, energetic, 128 bpm, C Minor]
Prompt structure:
Style Tags: [genre, sub-genre, vocal type, era, mood, bpm, key]
Instruments: [lead synth, punchy 808, sidechained pad, acoustic drums]
Scene/Mood: late-night drive through neon-lit city, feelings of nostalgic longing
Production: polished, radio-ready, wide stereo, dynamic build in chorus
Lyrics integration:
- Provide verse/chorus structure with [Verse], [Chorus], [Bridge] markers
- Specify vocal delivery in parentheses: (whispered), (belted), (harmonized)
- Use [Instrumental] for sections without vocals
- Keep lines concise; Suno favors rhythmic phrasing over prose density
Common fixes:
Muddy mix → add "bright master, crisp highs, defined bass separation"
Unwanted genre drift → lock style tags in brackets first; keep description aligned
Weak chorus → specify "anthemic chorus, layered vocals, raised energy, fuller arrangement"
Vocal intelligibility issues → "clear lead vocal, minimal effects on voice, upfront mix"
6. UDIO v1.5+ — SPECIFIC TECHNIQUES
Best for: natural vocal performances, audio-reference conditioning, extending existing audio.
Prompt structure:
Genre/Style: soulful R&B ballad with jazz chord voicings
Vocals: smooth male tenor, intimate and breathy, close-mic'd
Instruments: Rhodes piano, fretless bass, brushed drums, string quartet pad
Atmosphere: late-night jazz club, warm ambient mic bleed, analog warmth
Reference: (upload audio clip for style/voice matching)
Audio-reference workflow:
- Upload a reference track or vocal sample
- Describe what to preserve: "match the vocal timbre and reverb character of reference"
- Describe what to change: "same vocalist, but uptempo electronic arrangement"
Extend mode prompting:
- Provide context for continuation: "continue verse melody into chorus with rising tension"
- Specify transition type: "smooth segue", "hard cut", "build and drop"
Common fixes:
Overly smooth/generic sound → add specific artist or era references: "in the style of 1970s Stevie Wonder production"
Pitch drift in vocals → specify "tuned vocals, consistent pitch center"
Weak rhythmic groove → specify exact drum feel: "boom-bap kick on 1 and 3, snare on 2 and 4 with ghost notes"
7. ELEVENLABS — SPECIFIC TECHNIQUES
Best for: voice cloning, multilingual TTS, sound effects, audiobooks, podcasts, voiceovers.
Voice-design prompting:
Voice Description: "warm British male baritone, BBC documentary narrator, slight gravel, measured pace"
Stability: 0.35 (more variable, expressive) to 0.75 (consistent, controlled)
Similarity Boost: 0.60 (balanced) to 0.90 (very close to clone source)
Style Exaggeration: 0.20 (natural) to 0.60 (dramatic, animated)
Speaker Boost: on (improves clarity for non-cloned voices)
Sound-effect generation (ElevenLabs SFX):
- Describe physical cause and environment: "heavy wooden door creaking open in an old castle, stone acoustics, distant wind"
- Specify perspective: "first-person footstep on wet gravel", "distant thunder rolling across open plain"
- Layering syntax: "rain on tin roof + distant traffic rumble + occasional car horn"
Multilingual prompting:
- Specify accent and register: "Mexican Spanish, friendly customer-service tone"
- Code-switching hints: "primarily English with occasional French phrases, Parisian accent"
Common fixes:
Robotic/flat delivery → lower stability to 0.40, increase style exaggeration to 0.40, add emotional descriptors
Sibilance issues → "smooth sibilance, de-essed, warm mic"
Breathing artifacts → "natural breath pauses, not exaggerated"
8. STABLE AUDIO 3 — SPECIFIC TECHNIICS
Best for: open-weight generation, audio-to-audio transformation, precise timing control, sound design.
Prompt structure:
Duration: exact seconds (e.g., 45.5s, 120s)
Prompt: "ambient soundscape, distant whale songs, deep sub-bass drone, evolving granular textures, oceanic reverb"
Negative prompt: "percussion, rhythmic elements, vocal, melodic lead"
Audio-to-audio transformation:
- Input: existing audio file
- Transformation prompt: "same rhythm, but replace snare with clap, add reverb tail, warm analog saturation"
- Strength parameter: 0.3 (subtle) to 0.8 (heavy transformation)
Timing and structure:
- Use time-based descriptors: "intro 0–10s: ambient pad only; 10–30s: layered percussion enters; 30–45s: full arrangement"
Common fixes:
Timing misalignment → explicitly state beat positions: "kick drum on every beat, snare on 2 and 4"
Unwanted noise → use negative prompt: "hiss, hum, clipping, digital artifacts"
Lack of dynamics → "gradual build, crescendo, dynamic range, not flat"
9. UNIVERSAL PROMPT STRUCTURE (works across all music models)
[GENRE TAGS] — bracketed, comma-separated style anchors
[TEMPO & KEY] — exact BPM and key signature
[INSTRUMENTATION] — layered from low to high frequency
[VOCAL DESCRIPTION] — if applicable, include timbre and delivery
[MOOD & SCENE] — emotional narrative and imagined setting
[PRODUCTION QUALITY] — mixing and mastering descriptors
[STRUCTURE HINTS] — intro/verse/chorus/bridge/outro dynamics
Rule: Lead with genre and mood; follow with instrumentation; end with production quality.
