Subject: normalization From: shenke <shen.ke.828@xxxxxxxx> Date: Thu, 30 Nov 2006 10:28:41 +0800 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>------=_Part_50078_10879270.1164853721527 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline Dear list, Could anybody explain to me how to normalize the data from a wave file to 60-70dB in Matlab, with amplitude value 1 correspond to 30dB? To make the question clear, I have some sample wave files, I use wavread in Matlab to read in the data, the data will be between -1~1. Then I want to do amplitude normalization on the data as described above in order to make the data suitable for Meddis Model(Which is non-linear) to process. Thanks.
