🎯 Quick Start

Command Line Interface

Generate Music from Text

sunokiller generate "upbeat pop song with electric guitar and drums" -o music.wav

Generate Singing Voice

sunokiller sing "Happy birthday to you, happy birthday to you" -o birthday.wav -s female

Enhance Audio Quality

sunokiller enhance input.wav -o enhanced.wav

Python API

from sunokiller import AudioSynthesizer

# Initialize the synthesizer
synthesizer = AudioSynthesizer(
    device="cuda",  # or "cpu", "mps"
    use_quantization=True,  # Enable for faster inference
)

# Generate music from text
audio = synthesizer.generate_music(
    text="epic orchestral soundtrack with strings and percussion",
    duration=10.0,  # seconds
    temperature=1.0,
)

# Save to file
synthesizer.save_audio(audio, "output.wav")

# Generate singing voice
singing = synthesizer.generate_singing_voice(
    lyrics="Twinkle twinkle little star",
    voice_style="female",
    melody_description="gentle lullaby",
)

🏗️ Architecture

SUNOKILLER uses a three-stage pipeline:

1. Text-to-Music Transformer: Converts text descriptions to acoustic features (mel-spectrograms)

   • Based on SongGen and MusicGen architectures
   • T5 text encoder for semantic understanding
   • Efficient attention mechanisms

2. Diffusion Model (Optional): Refines audio quality

   • Fast DDIM sampling (50 steps vs 1000 in traditional models)
   • SpecDiff-GAN hybrid for stability
   • Conditional on mel-spectrograms

3. Vocos Vocoder: Converts to high-quality audio

   • Direct Fourier coefficient generation
   • 10x faster than WaveNet-style vocoders
   • Minimal quality degradation
