ToneTrace

ToneTrace is an audio analysis tool. The tool is designed to analyze audio files and generate corresponding time domain and frequency domain graphs. It utilizes the jgraph for graph generations, libsndfile library for audio file processing and fftw3 for fast Fourier transform computations.

Features

• Generates time domain graphs to visualize audio waveforms over time.
• Produces frequency domain graphs to display the frequency spectrum of audio signals.
• Supports various audio file formats.
• Capable of handling audio files with different sampling rates and channel counts.

Prerequisites

• libsndfile: An audio library for reading and writing files containing sampled sound.
• FFTW: A C library for computing the discrete Fourier transform (DFT).

Installation

1. Clone the ToneTrace repository.

2. Navigate to the ToneTrace directory.

3. Compile the program by running:

   make
   

Usage

To Jacob: Please run:

sh grade.sh

To generate time domain and frequency domain graphs for an audio file, use the following command:

./tonetrace -t <audio_file>
./tonetrace -f <audio_file> <target_second>

• -t: Generates a time domain graph for the specified audio file.
• -f: Produces a frequency domain graph for the audio file at the specified second.

Output

The program outputs .jgr files, which can be converted to graphical format using Jgraph. For instance, to convert a Jgraph file to a PDF, you can use the following command:

jgraph -P file.jgr | ps2pdf - > output.pdf
