> Works on **Windows / Linux (x64 & aarch64) / macOS** · NVIDIA / AMD / Apple Silicon / CPU. No `install.bat` — Pinokio sets up CUDA, Python 3.12, PyTorch and dependencies for you. Launcher: **[timoncool/HiggsAudio-Studio-pinokio](https://github.com/timoncool/HiggsAudio-Studio-pinokio)**

Generate expressive speech in 100+ languages, clone any voice from a reference clip, let a local LLM direct the delivery, and produce full **podcasts** and **audiobooks** — entirely on your machine. **100% offline**, no cloud, no API keys. Everything lives inside the folder: Python, dependencies, models, cache. Delete the folder — the app is gone.

Built on [Higgs Audio v3 TTS](https://huggingface.co/bosonai/higgs-audio-v3-tts-4b) by Boson AI — a 4B expressive TTS model with native multi-speaker and inline emotion/prosody control.

## Features

- **🎙️ TTS** — text → speech, 100+ languages; temperature, top-p/k, seed lock; autoplay; **⏹ Stop** interrupts generation on the fly (at the inference level); per-frame progress in the terminal.
- **🎭 Expression + 🤖 Director** — insert control tags (`<|emotion|>`, `<|sfx|>`, `<|prosody|>`, `<|style|>`) with buttons + an **Enrich** button: a lightweight local LLM normalizes the text and places emotion/sound/prosody tags by meaning.
- **🧬 Voice cloning** — zero-shot from a reference clip with auto-transcription (Moonshine ASR); preset library + on-demand Russian voice pack.
- **🎬 Podcast / Dialogue** — the LLM writes a multi-speaker script, each speaker its own voice → stitched with **loudness leveling across speakers** (LUFS −16, podcast standard — no speaker quieter than another).
- **📚 Audiobook** — narrator/character attribution with a persistent roster (same character = same voice), long-form with timbre carry-over + loudness normalization.
- **📦 Batch** — a list of texts → mass synthesis with a live log.
- **💾 Output format** — WAV / MP3 / FLAC / OGG; results saved to `output/` with timestamps.

**43 control tags:** 21 emotions, 10 prosody, 3 styles, 9 sounds. **AI director** — switchable GGUF model: Qwen3.5-9B (default, ~5.5 GB) / Qwen3.5-4B (light, ~2.5 GB), runs on GPU via llama.cpp. Higgs TTS quantization is on-the-fly (⚗️ experimental), auto by VRAM. **RU / EN** UI.

## System Requirements

### Platforms (via the Pinokio launcher)

| OS | GPU | Status | Acceleration |
|---|---|---|---|
| Windows 10/11 | NVIDIA RTX 30xx–50xx | ✅ tested | CUDA 12.8 + Triton (torch.compile ~2×) |
| Windows 10/11 | NVIDIA RTX 20xx | ✅ expected | CUDA 12.8 + Triton |
| Linux x64 | NVIDIA RTX 20xx–50xx | ✅ expected | CUDA 12.8 + Triton |
| Linux aarch64 | NVIDIA DGX Spark / Jetson | ✅ expected | CUDA 13.0 |
| Windows | AMD RDNA3+ | ✅ expected | DirectML |
| Linux | AMD RDNA3+ | ✅ expected | ROCm 6.3 |
| macOS | Apple Silicon M1–M4 | ✅ expected | MPS |
| macOS | Intel | ⚠️ CPU only | torch CPU |
| Any | CPU only | ⚠️ very slow | CPU |

> Higgs uses PyTorch SDPA (flash kernels built in) and does not need external Flash-Attention 2. The local `install.bat` build targets NVIDIA Windows; full cross-platform support is via [Pinokio](https://github.com/timoncool/HiggsAudio-Studio-pinokio).

### Memory (NVIDIA; TTS is quantized on the fly, the LLM director loads separately)

| VRAM | TTS mode | LLM director |
|------|----------|--------------|
| 24 GB+ | bf16 (~11 GB) | 9–12B in 4-bit (~6–8 GB) |
| 12 GB | 8-bit (~6–7 GB) | 4–9B in 4-bit (~3–6 GB) |
| 6–8 GB | 4-bit (~3.5 GB) | 2–4B in 4-bit (~1.5–3 GB) |
| CPU | works, very slow | — |

Models (~9 GB TTS + LLM) download automatically on first run.

## Quick Start

1. **Download** this repository.
2. **Install** — run **`install.bat`**, pick your GPU (CUDA 11.8 / 12.6 / 12.8 or CPU). It sets up portable Python, PyTorch and dependencies.
3. **Run** — run **`run.bat`**; the app opens in the browser, models download on first launch. Update with **`update.bat`**.

Or install one-click cross-platform via [Pinokio](https://pinokio.co/item?uri=https://github.com/timoncool/HiggsAudio-Studio-pinokio) — no `install.bat` needed.
