Naudio sound normalize

问题:

I am using Naudio and I have a stream which I need to read as array and then when I have found maximum I need to multiply each value with ( 1/ biggest ) and then I should have values in my array as [-1,1].

回答1:

I don't see really what you mean by "convert", but instead of the code you wrote you could just do:

var bytes = stream.ToArray();
var biggest = (float)bytes.Max();
var floats = bytes.Select(b => b / biggest).ToArray();

This will result with floats between 0 and 1, since bytes are always positive.

float to short:

float num1; short num6 = (short)num1;
