✨ Features

• Cross-platform: Windows / macOS / Linux support
• Lightweight: No heavy dependencies like numpy (~30KB)
• Exception-safe: Never crashes your app on playback failure
• Non-blocking: Asynchronous playback doesn't freeze your UI
• PyInstaller ready: Bundle into standalone executables

📦 Installation

pip install beep-lite

Optional: High-quality audio backend

pip install beep-lite[audio]

🚀 Usage

import beep_lite as beep

# Basic notifications
beep.ok()       # ✅ Success
beep.ng()       # ❌ Error / Failure
beep.warn()     # ⚠️ Warning
beep.crit()     # 🚨 Critical / Urgent

# Fun notifications
beep.moo()      # 🐄 Low frequency
beep.mew()      # 🐱 High frequency

# Scan results
beep.scan_ok()  # 📗 Scan success
beep.scan_ng()  # 📕 Scan failure

Using Sound enum

from beep_lite import play, Sound

play(Sound.OK)
play(Sound.SCAN_NG)

Preload at startup (optional)

from beep_lite import preload_all

# Call at app startup to reduce latency on first play
preload_all()

🔧 Backends

The library automatically selects the best available backend:

📋 Requirements

• Python 3.10+

Additional Requirements for Linux / Raspberry Pi

To use simpleaudio with the [audio] option, you need the ALSA development library:

# Debian / Ubuntu / Raspberry Pi OS
sudo apt-get install libasound2-dev

# Then install
pip install beep-lite[audio]

Note: If installed without [audio], the library falls back to terminal bell (\a), which requires no additional packages.
