Higgsfield Audio Prompting Guide

QUICK FACTS

Routing aids — read the linked sections for the full rules.

• Native-joint audio models: Kling 3.0, Seedance 2.0 / 1.5 Pro, Veo 3/3.1, Grok — all others add audio in post →
• Four layers to consider per prompt: Dialogue / SFX / Ambient / BGM →
• Suppressing a score: name the diegetic sound first, then the suppression as plain text; NO BGM vs No music. is OPEN (house-rulings P2-7) →
• Lip-sync is the most failure-prone feature: 3–8s clips, MCU framing, one speaking face, locked camera, no head-motion tokens; per-language sync-word budgets come from a third-party skill (EMPIRICAL, unmeasured here) →
• Seedance 2.0 @Audio1 is a conditioning INPUT — beat sync, the [AUDIO: Xs] script block, and the first-15s extraction trap →
• Scope an audio reference like an image one: name the property that rides, the property that must NOT, and where the excluded one comes from instead →
• Multi-clip assembly: one master track · cuts land on musical punctuation, never inside a sung vowel (ECU mouth-match is the one exception) · unified grain + LUT masks batch color drift →
• Cinema Studio 3.0 native joint audio (SCELA): describe audio as a separate section; specific foley beats generic moods →
• Seed Audio 1.0 (seed_audio, standalone) = whole-scene audio in ONE pass — multi-speaker dialogue + music + SFX + ambience mixed →
• Standalone Audio catalog (2026-09-26 snapshot): seed_audio, qwen_audio_tts (Qwen 3.0 TTS Flash — gained batch_size 1–4 on 2026-09-26, the only audio change since 08-01), text2speech_v2 (5 engines incl. cozy_voice), plus 3 game-pipeline-only tools — distinct from in-video joint audio →
• Voice change (voice_change) swaps the speaker in a finished video, keeping timing and visuals — no prompt; priced by duration. Voice cloning (create_voice) makes a reusable voice_type: 'element' voice — usable only once completed + is_audio_eligible →
