🎵 sound_rs

sound_rs is a high-performance Python audio library powered by Rust —
offering instant playback, low latency, and seamless NumPy integration.

Built for developers who want speed, stability, and simplicity in one package.

---

🚀 Features

✅ Play .wav files instantly
✅ Generate and play sounds directly from NumPy arrays
✅ Near-zero latency and minimal CPU usage thanks to Rust
✅ Safe, stable, and cross-platform
✅ Async-ready design for future streaming

---

🧠 Installation

pip install sound_rs

---

💻 Usage Examples

1️⃣ Basic Playback

import sound_rs

# Play a WAV file
sound_rs.play_audio("sound.wav")

2️⃣ From NumPy Array

import sound_rs
import numpy as np

# Generate 440 Hz sine wave (A4 note)
sample_rate = 44100
duration = 2.0
t = np.linspace(0, duration, int(sample_rate * duration), dtype=np.float32)
sine_wave = np.sin(2 * np.pi * 440 * t)

# Play directly from array (mono)
sound_rs.play_array(sine_wave, sample_rate)

3️⃣ Stream Large Files

# Play large audio file without full memory load
sound_rs.play_audio_streamed("large_file.wav")

4️⃣ Async Playback

# Play in background while doing other work
sound_rs.play_audio_async("background.wav")

5️⃣ Tone Generator

# Instantly generate and play a 440 Hz sine wave
sound_rs.play_sine_wave(440.0, 1.0, 44100)
