Guitar Tuner Application

This project is a guitar tuner application built for Linux and WSL. It uses the PortAudio library for real-time audio input and the FFTW library for frequency analysis. The application detects the frequency of the played guitar string and matches it to the closest musical note.

Features

• Real-time audio input processing using PortAudio.
• Frequency analysis using FFTW.
• Detection of the closest musical note to the detected frequency.
• User-friendly console output displaying the detected frequency and closest note.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Operating System: Linux or WSL.
• Dependencies:
  • PortAudio
  • FFTW

Installing Dependencies

To install the necessary libraries, run the following commands:

# Install PortAudio
sudo apt-get install portaudio19-dev

# Install FFTW
sudo apt-get install libfftw3-dev

Usage

1. Clone this repository to your local machine.
