Sparky Beep Provides beep support for a few services of server edition.

Overview

Sparky Beep offers audible notifications when selected system services start, stop or restart. The repository is arranged in a few key directories:

• README.md introduces Sparky Beep and lists required packages and installation commands.
• install.sh copies or removes init scripts, systemd service files and the main helper script. Run it with uninstall to remove everything.
• bin/ holds sparky-beep-run, a helper script that verifies the beep services are active and starts them if needed.
• init.d/ contains SysV init scripts such as beep_netdata, beep_samba, beep_sys, beep_webmin and sparky-beep. Each of these defines beep commands for different service states. For example:

case "$1" in
  start)
    beep -f 1000 -n -f 1500 -n -f 600 ...
    ;;
  stop)
    beep -f 100 -r 2 -l 10 -n -f 50 ...
    ;;
  restart)
    beep -f 100 -r 2 -l 10 ... ; beep -f 1000 ...
    ;;
esac

• system/ provides systemd unit files that link the beep scripts to services like netdata.service, samba-ad-dc.service, ssh.service and webmin.
• Additional metadata includes CHANGELOG, LICENSE and Debian-style copyright information.

Key Points

• The goal is to give audible feedback ("beeps") when services change state.
• Installation copies the scripts into system directories while uninstallation removes them.
• sparky-beep-run can be triggered from an init script and keeps the beep services enabled and running.

Musical Composer (NEW!)

Sparky Beep now includes a musical notation composer that lets you create melodic beeps using standard musical notation instead of raw frequencies!

Features:

• 🎵 Musical notation support - Write C4q D4q E4q instead of beep -f 261 -l 500 -n -f 293...
• 🎼 8 octaves - Full range from C0 to B8 (88 notes)
• 🎹 All chromatic notes - Sharps (#) and flats (b) supported
• ⏱️ Tempo control - Set BPM from 40-240
• 🔊 Ternary beep mode - Optional smoother sounds using ternary logic (requires compilation)

Quick Examples:

# Play C major scale
sparky-beep-compose -s "C4q D4q E4q F4q G4q A4q B4q C5q" -p

# Play Happy Birthday
sparky-beep-compose compositions/happy-birthday.beepmusic -p

# Custom tempo
sparky-beep-compose -s "tempo:140 C4h E4h G4h C5w" -p

Included Compositions:

• C Major Scale
• Happy Birthday
• Twinkle Twinkle Little Star
• Ode to Joy (Beethoven)
• Star Wars Theme
• Super Mario Bros Theme
• Startup/Shutdown fanfares
• Alert/notification sounds

Ternary Beep Engine (Advanced):

For smoother, more musical sounds, compile the optional ternary beep engine:

make              # Compile tbeep
sudo make install # Install ternary beep engine

# Enable ternary mode in config
sudo nano /etc/sparky-beep/beep.conf
# Change: BEEP_MODE="ternary"

# Test
sudo tbeep -f 440 -l 500

What is Ternary Beep?

Standard beep uses binary states (ON/OFF), creating harsh square waves. Ternary beep uses 3 states {-1, 0, +1}, approximating sine waves for smoother, more pleasant sounds!

Binary:  ┌─┐ ┌─┐ ┌─┐   (harsh, buzzy)
Ternary:   ╭─╮         (smooth, musical)
         ╭─╯ ╰─╮
        ─╯     ╰─

Documentation:

• COMPOSER.md - Complete composer documentation and examples
• config/beep.conf - Configuration file for beep mode and settings
• compositions/ - Pre-made musical compositions
• lib/notes.sh - Musical note library with all frequencies
