Use when generating music, soundtracks, jingles, or working with audio stems. Triggers include background music, soundtrack, jingle, music generation, stem extraction, cover, style transfer, or musical composition tasks.\n---\n\n# ACE-Step 1.5 Music Generation\n\nOpen-source music generation (MIT license) via `tools/music_gen.py`. Runs on RunPod serverless.\nRequires `RUNPOD_API_KEY` and `RUNPOD_ACESTEP_ENDPOINT_ID` in `.env` (run `--setup` to create endpoint).\n\n## Quick Reference\n\n```bash\n# Basic generation\npython tools/music_gen.py --prompt \"Upbeat tech corporate\" --duration 60 --output bg.mp3\n\n# With musical control\npython tools/music_gen.py --prompt \"Calm ambient piano\" --duration 30 --bpm 72 --key \"D Major\" --output ambient.mp3\n\n# Scene presets (video production)\npython tools/music_gen.py --preset corporate-bg --duration 60 --output bg.mp3\npython tools/music_gen.py --preset tension --duration 20 --output problem.mp3\npython tools/music_gen.py --preset cta --brand digital-samba --duration 15 --output cta.mp3\n\n# Vocals with lyrics\npython tools/music_gen.py --prompt \"Indie pop jingle\" --lyrics \"[verse]\\nBuild it better\\nShip it faster\" --duration 30 --output jingle.mp3\n\n# Cover / style transfer\npython tools/music_gen.py --cover --reference theme.mp3 --prompt \"Jazz piano version\" --duration 60 --output jazz_cover.mp3\n\n# Stem extraction\npython tools/music_gen.py --extract vocals --input mixed.mp3 --output vocals.mp3\n\n# List presets\npython tools/music_gen.py --list-presets\n```\n\n## Creating a Song (Step by Step)\n\n### 1. Instrumental background track (simplest)\n```bash\npython tools/music_gen.py --prompt \"Upbeat indie rock, driving drums, jangly guitar\" --duration 60 --bpm 120 --key \"G Major\" --output track.mp3\n```\n\n### 2. Song with vocals and lyrics\nWrite lyrics in a temp file or pass inline. Use structure tags to control song sections.\n\n```bash\n# Write lyrics to a file first (recommended for longer songs)\ncat > /tmp/lyrics.txt << 'LYRICS'\n[Verse 1]\nWalking through the morning light\nCoffee in my hand feels right\nAnother day to build and dream\nNothing's ever what it seems\n\n[Chorus - anthemic]\nWE KEEP MOVING FORWARD\nThrough the noise and doubt\nWe keep moving forward\nThat's what it's about\n\n[Verse 2]\nScreens are glowing late at night\nShipping code until it's right\nThe deadline's close but so are we\nAlmost there, just wait and see\n\n[Chorus - bigger]\nWE KEEP MOVING FORWARD\nThrough the noise and doubt\nWe keep moving forward\nThat's what it's about\n\n[Outro - fade]\n(Moving forward...)\nLYRICS\n\n# Generate the song\npython tools/music_gen.py \\\n  --prompt \"Upbeat indie rock anthem, male vocal, driving drums, electric guitar, studio polish\" \\\n  --lyrics \"$(cat /tmp/lyrics.txt)\" \\\n  --duration 60 \\\n  --bpm 128 \\\n  --key \"G Major\" \\\n  --output my_song.mp3\n```\n\n### 3. Using a preset for video background\n```bash\npython tools/music_gen.py --preset tension --duration 20 --output problem_scene.mp3\n```\n\n### Key tips for good results\n- **Caption = overall style** (genre, instruments, mood, production quality)\n- **Lyrics = temporal structure** (verse/chorus flow, vocal delivery)\n- **UPPERCASE in lyrics** = high vocal intensity\n- **Parentheses** = background vocals: \"We rise (together)\"\n- **Keep 6-10 syllables per line** for natural rhythm\n- **Don't describe the melody in the caption** — describe the *sound* and *feeling*\n- **Use `--seed`** to lock randomness when iterating on prompt/lyrics\n\n## Scene Presets\n\n| Preset | BPM | Key | Use Case |\n|--------|-----|-----|----------|\n| `corporate-bg` | 110 | C Major | Professional background, presentations |\n| `upbeat-tech` | 128 | G Major | Product launches, tech demos |\n| `ambient` | 72 | D Major | Overview slides, reflective content |\n| `dramatic` | 90 | D Minor | Reveals, announcements |\n| `tension` | 85 | A Minor | Problem statements, challenges |\n| `hopeful` | 120 | C Major | Solution reveals, resolutions |\n| `cta` | 135 | E Major | Call to action, closing energy |\n| `lofi` | 85 | F Major | Screen recordings, coding demos |\n\n## Task Types\n\n### text2music (default)\nGenerate music from text prompt + optional lyrics.\n\n### cover\nStyle transfer from reference audio. Control blend with `--cover-strength` (0.0-1.0):\n- **0.2** — Loose style inspiration (more creative freedom)\n- **0.5** — Balanced style transfer\n- **0.7** — Close to original structure (default)\n- **1.0** — Maximum fidelity to source\n\n### extract\nStem separation — isolate individual tracks from mixed audio.\nTracks: `vocals`, `drums`, `bass`, `guitar`, `piano`, `keyboard`, `strings`, `brass`, `woodwinds`, `other`\n\n### repaint (future)\nRegenerate a specific time segment within existing audio while preserving the rest.\n\n### lego (future, requires base model)\nGenerate individual instrument tracks within an existing audio context.\n\n### complete (future, requires base model)\nExtend partial compositions by adding specified instruments.\n\n## Prompt Engineering\n\n### Caption Writing — Layer Dimensions\n\nWrite captions by layering multiple descriptive dimensions rather than single-word descriptions.\n\n**Dimensions to include:**\n- **Genre/Style**: pop, rock, jazz, electronic, lo-fi, synthwave, orchestral\n- **Emotion/Mood**: melancholic, euphoric, dreamy, nostalgic, intimate, tense\n- **Instruments**: acoustic guitar, synth pads, 808 drums, strings, brass, piano\n- **Timbre**: warm, crisp, airy, punchy, lush, polished, raw\n- **Era**: \"80s synth-pop\", \"modern indie\", \"classical romantic\"\n- **Production**: lo-fi, studio-polished, live recording, cinematic\n- **Vocal**: breathy, powerful, falsetto, raspy, spoken word (or \"instrumental\")\n\n**Good**: \"Slow melancholic piano ballad with intimate female vocal, warm strings building to powerful chorus, studio-polished production\"\n**Bad**: \"Sad song\"\n\n### Key Principles\n\n1. **Specificity over vagueness** — describe instruments, mood, production style\n2. **Avoid contradictions** — don't request \"classical strings\" and \"hardcore metal\" simultaneously\n3. **Repetition reinforces priority** — repeat important elements for emphasis\n4. **Sparse captions = more creative freedom** — detailed captions constrain the model\n5. **Use metadata params for BPM/key** — don't write \"120 BPM\" in the caption, use `--bpm 120`\n\n### Lyrics Formatting\n\n**Structure tags** (use in lyrics, not caption):\n```\n[Intro]\n[Verse]\n[Chorus]\n[Bridge]\n[Outro]\n[Instrumental]\n[Guitar Solo]\n[Build]\n[Drop]\n[Breakdown]\n```\n\n**Vocal control** (prefix lines or sections):\n```\n[raspy vocal]\n[whispered]\n[falsetto]\n[powerful belting]\n[harmonies]\n[ad-lib]\n```\n\n**Energy indicators:**\n- UPPERCASE = high intensity (\"WE RISE ABOVE\")\n- Parentheses = background vocals (\"We rise (together)\")\n- Keep 6-10 syllables per line within sections for natural rhythm\n\n**Example — Tech Product Jingle:**\n```\n[Verse]\nBuild it better, ship it faster\nEvery feature tells a story\n\n[Chorus - anthemic]\nTHIS IS YOUR PLATFORM\nYour vision, your stage\nDigital Samba, every page\n\n[Outro - fade]\n(Build it better...)\n```\n\n## Video Production Integration\n\n### Music for Scene Types\n\n| Scene | Preset | Duration | Notes |\n|-------|--------|----------|-------|\n| Title | `dramatic` or `ambient` | 3-5s | Short, mood-setting |\n| Problem | `tension` | 10-15s | Dark, unsettling |\n| Solution | `hopeful` | 10-15s | Relief, optimism |\n| Demo | `lofi` or `corporate-bg` | 30-120s | Non-distracting, matches demo length |\n| Stats | `upbeat-tech` | 8-12s | Building credibility |\n| CTA | `cta` | 5-10s | Maximum energy, punchy |\n| Credits | `ambient` | 5-10s | Gentle fade-out |\n\n### Timing Workflow\n\n1. Plan scene durations first (from voiceover script)\n2. Generate music to match: `--duration <scene_seconds>`\n3. Music duration is precise (within 0.1s of requested)\n4. For background music spanning multiple scenes: generate one long track\n\n### Combining with Voiceover\n\nBackground music should be mixed at 10-20% volume in Remotion:\n```tsx\n<Audio src={staticFile('voiceover.mp3')} volume={1} />\n<Audio src={staticFile('bg-music.mp3')} volume={0.15} />\n```\n\nFor music under narration: use instrumental presets (`corporate-bg`, `ambient`, `lofi`).\nFor music-forward scenes (title, CTA): can use higher volume or vocal tracks.\n\n### Brand Consistency\n\nUse `--brand <name>` to load hints from `brands/<name>/brand.json`.\nUse `--cover --reference brand_theme.mp3` to create variations of a brand's sonic identity.\nFor consistent sound across a project: fix the seed (`--seed 42`) and vary only duration/prompt.\n\n## Technical Details\n\n- **Output**: 48kHz MP3/WAV/FLAC\n- **Duration range**: 10-600 seconds\n- **BPM range**: 30-300\n- **Inference**: ~2-3s on GPU (turbo, 8 steps), ~40-60s on Mac MPS\n- **Turbo model**: 8 steps, no CFG needed, fast and good quality\n- **Shift parameter**: 3.0 recommended for turbo (improves quality)\n\n### When NOT to use ACE-Step\n- **Voice cloning** — use Qwen3-TTS or ElevenLabs instead\n- **Sound effects** — use ElevenLabs SFX (`tools/sfx.py`)\n- **Speech/narration** — use voiceover tools, not music gen\n- **Stem extraction from video** — extract audio first with FFmpeg, then use `--extract`\n","tagline":"AI music generation with ACE-Step 1.5 — background music, vocal tracks, covers, stem extraction for video production.
