# AudioCraft: Audio Generation

Comprehensive guide to using Meta's AudioCraft for text-to-music and text-to-audio generation with MusicGen, AudioGen, and EnCodec.

## When to use AudioCraft

**Use AudioCraft when:**
- Need to generate music from text descriptions
- Creating sound effects and environmental audio
- Building music generation applications
- Need melody-conditioned music generation
- Want stereo audio output
- Require controllable music generation with style transfer

**Key features:**
- **MusicGen**: Text-to-music generation with melody conditioning
- **AudioGen**: Text-to-sound effects generation
- **EnCodec**: High-fidelity neural audio codec
- **Multiple model sizes**: Small (300M) to Large (3.3B)
- **Stereo support**: Full stereo audio generation
- **Style conditioning**: MusicGen-Style for reference-based generation

**Use alternatives instead:**
- **Stable Audio**: For longer commercial music generation
- **Bark**: For text-to-speech with music/sound effects
- **Riffusion**: For spectogram-based music generation
- **OpenAI Jukebox**: For raw audio generation with lyrics

## Quick start

### Installation

```bash
# From PyPI
pip install audiocraft

# From GitHub (latest)
pip install git+https://github.com/facebookresearch/audiocraft.git

# Or use HuggingFace Transformers
pip install transformers torch torchaudio
```

### Basic text-to-music (AudioCraft)

```python
import torchaudio
from audiocraft.models import MusicGen

# Load model
model = MusicGen.get_pretrained('facebook/musicgen-small')

# Set generation parameters
model.set_generation_params(
    duration=8,  # seconds
    top_k=250,
    temperature=1.0
)

# Generate from text
descriptions = ["happy upbeat electronic dance music with synths"]
wav = model.generate(descriptions)

# Save audio
torchaudio.save("output.wav", wav[0].cpu(), sample_rate=32000)
```

### Using HuggingFace Transformers

```python
from transformers import AutoProcessor, MusicgenForConditionalGeneration
import scipy

# Load model and processor
processor = AutoProcessor.from_pretrained("facebook/musicgen-small")
model = MusicgenForConditionalGeneration.from_pretrained("facebook/musicgen-small")
model.to("cuda")

# Generate music
inputs = processor(
    text=["80s pop track with bassy drums and synth"],
    padding=True,
    return_tensors="pt"
).to("cuda")

audio_values = model.generate(
    **inputs,
    do_sample=True,
    guidance_scale=3,
    max_new_tokens=256
)

# Save
sampling_rate = model.config.audio_encoder.sampling_rate
scipy.io.wavfile.write("output.wav", rate=sampling_rate, data=audio_values[0, 0].cpu().numpy())
```

### Text-to-sound with AudioGen

```python
from audiocraft.models import AudioGen

# Load AudioGen
model = AudioGen.get_pretrained('facebook/audiogen-medium')

model.set_generation_params(duration=5)

# Generate sound effects
descriptions = ["dog barking in a park with birds chirping"]
wav = model.generate(descriptions)

torchaudio.save("sound.wav", wav[0].cpu(), sample_rate=16000)
```
