Tip
The Encoder.Encode returns an int.
If it's > 0, encoding succeeded and this int represents the length of the encoded audio in the output array. You'll need to copy the encoded audio from the output.
If it's < 0, encoding has failed and the int actually represents the error code
// Assuming pcm is the float[] you want to encode
// The output array should be equal to the pcm array size in bytes, hence multuplied by 4
byte[] output = new byte[pcm.Length * 4];
int encodeResult = encoder.Encode(pcm, output);
if(encodedResult > 0) {
byte[] encodedBytes = new byte[encodeResult];
Array.Copy(encodeBuffer, encodedBytes, encodedBytes.Length);
// encodedBytes now has the encoded audio ready for your use
}
else {
// Get the error
ErrorCode errorCode = (ErrorCode)encodeResult;
}
