A package to generate metronome tracks from Guitar Pro files.

Guitar Pro Metronome Generator

A Python script that generates a metronome track from Guitar Pro files.

Features

• Extracts tempo information from Guitar Pro (.gp) files
• Generates a WAV file containing metronome clicks
• Supports variable tempo changes throughout the piece
• Supports tempo change in the middle of a bar

Prerequisites

• Python 3.6 or higher
• Required Python packages:
  • numpy

Installation

1. Clone this repository or download the script
2. Install the required packages:

pip install numpy

Usage

Run the script from the command line with two arguments:

1. Path to the input Guitar Pro file
2. Desired output WAV file path

python metronome_generator.py input.gp output.wav

Example:

python metronome_generator.py mysong.gp mysong_metronome.wav

How It Works

1. Extracts the score.gpif file from the Guitar Pro file (XML format)
2. Parses the XML to find tempo changes and their positions
3. Generates click sounds at appropriate intervals
4. Creates a WAV file with the metronome track

Technical Details

• Sample rate: 44100 Hz
• Audio format: 16-bit mono WAV
• Click duration: 0.02 seconds

  • Support different sounds for the first beat of each bar (accent beat)
• Extended format support:
  • Add support for .mp3 export
  • Add compatibility with legacy Guitar Pro formats (.gpx, .gp5)
  • Implement broader Guitar Pro version compatibility
• Enhanced features:
  • Support for different time signatures
  • Visual metronome interface
