## 1. Try it now

**Four ways:**

- 🎧 **Hear it now** - [latentscore.com/demo](https://latentscore.com/demo). Browser, no install.
- 🐳 **Run the demo + JupyterLab locally** - `docker compose` builds the full demo from source in an isolated environment — demo UI **and** a JupyterLab playground, no local Python needed. ~15 min first build. See [Try the demo](#2-try-the-demo).
- 🟧 [**Open in Colab**](https://colab.research.google.com/github/prabal-rje/latentscore/blob/main/notebooks/quickstart-colab.ipynb) - free CPU runtime, no local setup, no key required.
- 🛠 **Build with it locally** - `pip install latentscore` on macOS or Linux (Python 3.11/3.12). Secondary path — use Docker for the full demo. See [Try the SDK](#4-try-the-sdk).

```python
import latentscore as ls

ls.render("morning coffee shop").play()
```

That's it. One line. You get audio playing on your speakers.

---

## 2. Try the demo

**No install needed:** open **[latentscore.com/demo](https://latentscore.com/demo)** in your browser.

**Run it locally** — tested on Linux, macOS, and Windows with [Docker Desktop](https://www.docker.com/products/docker-desktop/) (WSL2 backend on Windows).

**Build from source** (~15 min first time, near-instant after):

```bash
docker compose -f demo/docker-compose.yml up --build
```

> ⚠️ **Apple Silicon (M-series) Macs:** the build defaults to `linux/amd64` for reproducibility,
> which runs under emulation and is slow. For a native, much faster build, prefix the command:
>
> ```bash
> LATENTSCORE_DOCKER_PLATFORM=linux/arm64 docker compose -f demo/docker-compose.yml up --build
> ```

The first prompt after build takes ~30 seconds as model weights load; subsequent responses are near-instant.

Then open:

- [`localhost:4242`](http://localhost:4242) - demo UI
- [`localhost:8889`](http://localhost:8889) - JupyterLab playground (SDK pre-installed)

See the [demo documentation](demo/) for architecture, dev setup, and troubleshooting.

## 4. Try the SDK

> 🐳 **For the full demo, use Docker.** The `pip install` path is for
> library/scripting use on macOS and Linux.
>
> 🟧 **Easiest SDK path:** [Open the Colab notebook](https://colab.research.google.com/github/prabal-rje/latentscore/blob/main/notebooks/quickstart-colab.ipynb) — free CPU
> runtime, no install, no system deps to wrangle.

If you'd rather install locally, read on.

> ⚠️ Local pip installs may require system audio libraries depending
> on your OS. If you hit issues, use Docker or
> [Colab](https://colab.research.google.com/github/prabal-rje/latentscore/blob/main/notebooks/quickstart-colab.ipynb)
> instead — both include all dependencies.

### 4.1 Requirements

- **OS** — macOS or Linux. Windows: use Docker Desktop with the WSL2 backend for the demo. Native Windows pip is unsupported, and WSL2 pip is not part of the supported SDK path.
- **Python 3.11 or 3.12** - local SDK installs require this range via package metadata. For other Python versions, use Docker or Colab.

### 4.2 Install

With `venv` (regular Python):

```bash
python3.12 -m venv .venv
source .venv/bin/activate
pip install latentscore
```

With `conda`:

```bash
conda create -n latentscore python=3.12 -y
conda activate latentscore
pip install latentscore
```

> [!NOTE]
> **Linux: smaller CPU-only install.** PyTorch's default Linux wheel
> bundles ~5 GB of CUDA libraries. LatentScore is CPU-only, so you can
> skip them with PyTorch's CPU index:
>
> ```bash
> pip install latentscore --extra-index-url https://download.pytorch.org/whl/cpu
> ```
>
> macOS is CPU-only already, so plain `pip install` is fine there.

### 4.3 What you get

The default install gives you text prompts, full parameter control, and local playback. See the [Quick start](#6-quick-start) below.

Optional extras:

| Install | Adds |
|---|---|
| `pip install "latentscore[external]"` | bring-your-own hosted LLM via [LiteLLM](https://docs.litellm.ai/) (Anthropic, Gemini, OpenAI, &hellip;) |
| `pip install "latentscore[heavy]"` | CLAP audio-based retrieval (`fast_heavy` model) |
| 🚧 `pip install "latentscore[expressive]"` | local LLM inference. **Extremely experimental, under testing.** |

### 4.4 Verify your install

```bash
latentscore doctor --strict --offline
```

Exits non-zero with a clear hint if anything's broken. Add `--json` for machine-readable output.

---

## 5. CLI

> ⚠️ The CLI ships with the SDK install — same system-deps caveats as [Try the SDK](#4-try-the-sdk) above. Skip the headache by running [the Colab notebook](https://colab.research.google.com/github/prabal-rje/latentscore/blob/main/notebooks/quickstart-colab.ipynb) instead; most of these CLI commands have equivalent Python calls (`ls.prefetch(...)`, `ls.render(...)`) you can run there.

```bash
# Verify your install
latentscore doctor                       # human-readable summary
latentscore doctor --strict --offline    # nonzero exit if anything's broken
latentscore doctor --json                # machine-readable output

# Pre-download model assets (otherwise the first render call appears to hang)
latentscore download fast                # ~90 MB, MiniLM embedding model
latentscore download fast_heavy          # ~1.8 GB, LAION-CLAP weights

# Render a sample clip
latentscore demo                         # play a short ambient clip
latentscore demo --duration 30 --output ambient.wav   # 30 seconds, save to file
```

---

## 6. Quick start

> 🟧 **Don't want to install?** [Try the same code in Colab](https://colab.research.google.com/github/prabal-rje/latentscore/blob/main/notebooks/quickstart-colab.ipynb) — free CPU runtime, no install.

### 6.1 Render and play

```python
import latentscore as ls

# Optional one-time setup: pre-download the embedding model (~90 MB) so
# the first render() call doesn't appear to hang. The download happens
# on the first render anyway; this just makes it explicit and visible.
ls.prefetch("fast")

audio = ls.render("morning coffee shop", duration=10.0)
audio.play()              # plays on your speakers
audio.save("output.wav")  # save to WAV
```

### 6.2 Different vibes

```python
ls.render("morning coffee shop").play()
ls.render("thunderstorm on a tin roof").play()
ls.render("tension over a treasured object").play()
```

---

## 7. Controlling the sound

Beyond text prompts, you can drive synthesis directly:

```python
import latentscore as ls

# Full control: build a MusicConfig with human-readable labels
config = ls.MusicConfig(
    tempo="slow",
    mode="dorian",
    root="d",
    bass="drone",
    pad="ambient_drift",
    melody="contemplative",
    rhythm="minimal",
    texture="shimmer",
    echo="heavy",
    density=3,
    brightness="dark",
    space="vast",
)
ls.render(config, duration=10.0).play()

# Or start from a vibe and slam knobs to opposites
ls.render(
    "morning coffee shop",
    update=ls.MusicConfigUpdate(
        tempo="very_fast",
        brightness="very_dark",
        echo="infinite",
    ),
).play()
```

See the [full documentation](docs/library.md) for the parameter
reference, relative-step updates, streaming, live playlists, async
API, and bring-your-own-LLM cookbook.
