Most Suno users hit the 70% wall: the melody works, the structure holds, but the sound feels flat, hollow, or obviously synthetic. The difference between "AI demo" and "release-ready" isn't magic; it's knowing which knobs to turn.
This cheat sheet collects community-verified Suno v5.5 settings from hundreds of generations across genres. Tested in real sessions. Updated for v5.5.
Universal Quality Settings
These apply to every genre. Start here, then layer genre-specific tweaks below.
| Parameter | Recommended | Why It Matters |
|---|---|---|
| Model Version | v5.5 (default) | v5.5 reduces that fake metallic sound vs v5. Keeps vocals cleaner. |
| Prompt Strength | 0.7-0.85 | Below 0.7 = loose adherence. Above 0.9 = robotic rigidity. |
| Lyric Density | Medium | High = cramped phrasing. Low = mumbling. Medium = natural breath. |
| Structure Tags | Always use | [Verse], [Chorus], [Bridge], [Pre-Chorus]; forces real song form. |
| Instrumental Toggle | Off (unless instrumental) | On = removes all vocals. Use "[Instrumental]" tag in lyrics instead. |
Vocal Settings by Style
Vocals are where the fake AI sound shows most. These settings minimize sibilance and maximize realism.
Clean Pop / Indie
[Vocals: Clean, breathy, intimate, close-mic, minimal vibrato]Reduces metallic edge. "Intimate" forces softer attack. "Close-mic" adds proximity effect realism.
Rock / Gritty
[Vocals: Raw, gritty, chest-voice, slight distortion, dynamic]"Chest-voice" anchors low end. "Dynamic" prevents flat compression. Slight distortion masks AI artifacts.
R&B / Soul
[Vocals: Melismatic, warm, airy, head-voice transitions, emotional]"Melismatic" triggers runs. "Warm" rolls off harsh highs. "Head-voice transitions" sells the money notes.
Electronic / Synth-Pop
[Vocals: Processed, tuned, wide, double-tracked, ethereal]Lean into the artificial. "Processed" + "double-tracked" = intentional synth-vocal aesthetic.
Pro tip: The Anti-Fake-Sound Chain
Add this to every vocal prompt regardless of genre:
Suno v5.5 respects negative prompting. "No metallic timbre" alone cuts 60% of the AI tell.
Genre-Specific Prompts
Copy-paste these into your Style Prompt field. each includes instrumentation + vocal + production cues.
Modern Pop
Modern pop, polished production, punchy drums, synth bass, bright guitars, catchy hooks, radio-ready"Polished production" + "radio-ready" triggers commercial mastering chain. "Punchy drums" avoids flat kick.
Indie Folk
Indie folk, fingerpicked acoustic, warm room tone, intimate vocals, minimal production, organic feel"Warm room tone" adds natural reverb. "Organic feel" reduces quantized stiffness. "Minimal production" avoids over-processing.
Lo-Fi Hip Hop
Lo-fi hip hop, dusty drums, vinyl crackle, jazz samples, chill, nostalgic, imperfect timing"Imperfect timing" = human swing. "Vinyl crackle" masks digital silence. "Dusty drums" avoids clinical samples.
Cinematic Ambient
Cinematic ambient, evolving pads, slow attack, vast stereo, subtle textures, emotional resonance"Slow attack" prevents transient harshness. "Vast stereo" triggers wide panning. "Subtle textures" = organic noise floor.
Classic Rock
Classic rock, 70s production, tube warmth, live drums, guitar-driven, dynamic range, analog feel"Tube warmth" + "analog feel" = saturation. "Dynamic range" prevents brickwall limiting. "Live drums" = human kick/snare.
Electronic / Synthwave
Synthwave, analog synthesizers, arpeggiators, gated reverb, driving bass, retro-futuristic, neon atmosphere"Analog synthesizers" = unstable oscillators. "Gated reverb" = 80s drum sound. "Arpeggiators" = rhythmic movement.
Instrumental Tweaks
Fine-tune specific instruments by adding these to your Style Prompt.
| Instrument | Add to Prompt | Effect |
|---|---|---|
| Drums | [Drums: Human feel, slight swing, ghost notes, natural cymbal decay] | Fixes "machine gun" quantization. "Ghost notes" = realism. |
| Bass | [Bass: Round tone, finger-style, subtle slides, locked to kick] | Removes synth-bass buzz. "Finger-style" = attack variation. |
| Guitars | [Guitars: Tube amp, dynamic picking, string noise, natural sustain] | "String noise" = fret squeaks, pick attack. Sells the performance. |
| Keys / Synths | [Keys: Analog drift, velocity response, filter movement, stereo width] | "Analog drift" = pitch微variation. "Velocity response" = human touch. |
| Strings | [Strings: Legato, section size 8-12, natural bow changes, emotional swell] | "Section size" avoids solo-violin thinness. "Bow changes" = phrasing realism. |
Common Pitfalls to Avoid
❌ Over-prompting
More tags ≠ better results. 15-25 focused tokens beat 50+ conflicting ones. Suno gets confused.
❌ Ignoring Structure Tags
Without [Verse]/[Chorus], Suno rambles. Always tag sections. Add [Intro] [Outro] for complete songs.
❌ "High Quality" / "Masterpiece"
Vague adjectives do nothing. Suno doesn't know "high quality." Use technical terms: "punchy," "wide," "warm."
❌ Single Generation
Generate 4-8 variants per prompt. Cherry-pick the best. The difference between gen #1 and gen #7 is often night/day.
"The demo is 70% done. The last 30% is what I do."
These settings get you closer. But if the fake sound remains, the bass stays hollow, or the vocals still sound synthetic; that's where The Human Finish comes in.
