mu2lin

Convert mu-law audio signal to linear

Syntax

• y = mu2lin(mu)
  

Description

y = mu2lin(mu) converts mu-law encoded 8-bit audio signals, stored as "flints" in the range 0  mu  255, to linear signal amplitude in the range -s < Y < s where s = 32124/32768 ~= .9803. The input mu is often obtained using fread(...,'uchar') to read byte-encoded audio files. "Flints" are MATLAB integers -- floating-point numbers whose values are integers.
