Thanks a lot for replying, The question now is , after subtracting 32767 from each unsigned sample, will the new signed samples represent the same original voice ? ???? For explanation, assume "Hi" is said in 8000 unsigned sample ,if i subtract 32767 from each sample and play the resulting 8000 sample as signed PCM samples,will they be "Hi" ?! Forgive me about my questions ,
