# mu2lin

## Purpose

µ-law to linear conversion.

## Synopsis

    y = mu2lin(mu)

## Description

`y = mu2lin(mu)` converts µ-law encoded 8-bit audio signals, stored as flints (floating-point integers) in the range 0 <= `mu` <= 255, to linear audio signal amplitudes in the range `-s` <= `y` <= `s`. The value of `s` is 32124/32768, or approximately 0.9803.

The µ-law encoded input is often obtained using

    fread(...,'uchar')

to read byte-encoded audio files.
