Throws an exception like this

An audio file converted to PCM will be many 10s if not hundreds of MB, so not necessarily surprising that it can't be allocated. The recommended way of processing the audio in a file is to work your way through it in buffers (e.g. 1 second of audio at a time)

How to through it in buffers? like this:

int windowSize = 1048576 * 2000;
byte[] buffer = new byte[windowSize];
long readLiength = 0;
while ((readLiength = await _audioFileReader.ReadAsync(buffer.AsMemory(0, windowSize))) > 0)
{
float[] wavdata = new float[buffer.Length / 4];
Buffer.BlockCopy(buffer, 0, wavdata, 0, buffer.Length);
float[] samples = wavdata.Select((float x) => x * 32768f).ToArray();
result.Add(samples);
buffer = new byte[windowSize];
}
