mu-law encoding to linear signal

Calling Sequence




real vector


real vector


Utility fct: y=mu2lin(mu) converts mu-law encoded 8-bit audio signals, stored 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 mget(...,'uc') to read byte-encoded audio files. Translation of C program by Craig Reese: IDA/Supercomputing Research Center Joe Campbell: Department of Defense
