RIFF/WAV audio file parser in C++

RIFF/WAV-Parser

A C++ library for parsing WAV files.
Parsing should work for most generic RIFF types as well, however the code to extract the actual
data section must be implemented for every specific file type.

For the time being file modification functionality is not provided.
If you are using this library and need to modify a WAV file you will have to parse its data using the
functionality provided, then work in raw bytes in order to create non-corrupt headers/data.

Example Usage

#include "WAVData.h"

void some_function()
{
    ...
    
    wav::WAVData wavExample("path/to/your/file.wav");

    // You can also initialize through:
    // wav::WAVData wavExample();
    // wavExample.ParseFile("path/to/your/file.wav");

    if (wavExample.GetDataPointer() == nullptr)
    {
        // Parsing did not go as planned, check program output
    }

    std::cout << wavExample << std::endl;

    uint32_t* wavSamples = wavExample.GetSamples();

    // Mono audio data 
    for (int i = 0; i < wavExamples.GetNumberOfSamples(); i++)
    {
        // Sample operations
        // Access sample through *(wavSamples + i)
    }

    // Stereo audio data
    for (int i = 0; i < wavExamples.GetNumberOfSamples(); i++)
    {
        if (i % 2 == 0)
        {
            // Left channel data
            ...
        }
        else
        {
            // Right channel data
            ...
        }
    }

    ...
}

TODO

1. Add WAV Header/Data modification functionality through the API.
2. Provide support for software specific metadata extraction (LIST chunks are currently saved as raw bytes)
