Python Projects

A monorepo containing two independent Python GUI applications.

Projects

1. Piano Note Detector (note_detector/)

A real-time piano note detection application that listens to microphone input and displays the detected musical note on a GUI.

How it works:

• Captures audio via microphone at 44.1 kHz using PyAudio
• Applies FFT with Hanning windowing and spectral smoothing
• Detects the fundamental frequency and maps it to the nearest piano note (A0 to C8)
• Features octave-specific accuracy improvements and dynamic noise thresholding
• Displays the stable note in a Tkinter window with a rolling buffer for flicker reduction

Dependencies: numpy, scipy, pyaudio

cd note_detector
pip install numpy scipy pyaudio
python piano_note_detector.py

2. Screen Brightness Control (screen-brightness-control/)

A cross-platform desktop GUI application for viewing and adjusting monitor brightness.

Features:

• Displays current brightness level of all connected monitors
• Set brightness via text entry (0-100) or Enter key
• Up/Down arrow keys adjust brightness in 5-step increments with debounce
• Multi-monitor support
• System theme awareness (light/dark mode)

Dependencies: customtkinter, screen-brightness-control

cd screen-brightness-control
pip install customtkinter screen-brightness-control
python brightness_controller.pyw
