does AudioFileReader support .flac files?

[yueyinqiu]

Hello! I'm trying to read some .flac files with NAudio but I've met some problems.

I think the following code could describe it more clear:

using NAudio.Wave;

var path = "p225_001_mic2.flac";

using var reader = new AudioFileReader(path);
Console.WriteLine(reader.Length / sizeof(float)); // 96000

var buffer = new float[1];
for(int i = 0; ; i++)
{
    var b = reader.Read(buffer, 0, 1);
    if (b < 1)
    {
        Console.WriteLine(i); // 98473
        break;
    }
}

And this is the audio file:

p225_001_mic2.zip

I assume that reader.Length / sizeof(float) should be equal to the final value of i. Actually It works well when it's a .wav file, but it doesn't seem to work on .flac files.

Meanwhile, the following codes just print -1:

using NAudio.Wave;

var path = "p225_001_mic2.flac";

using var reader = new AudioFileReader(path);
Console.WriteLine(reader.ReadByte()); // -1

So have I missed something? Or perhaps AudioFileReader actually does not support flac files at all (but I have seen someone else are using NAudio to play .flac files, like #1072)?
