Subject: Re: Measuring audio quality From: XAVIER ANGUERA MIRO <xanguera@xxxxxxxx> Date: Mon, 13 Jun 2011 12:50:37 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Thank you Emmanuel for your fast answer. I have looked at the links you propose, but I have a doubt whether the tools expect to have a clean signal as reference? In my tests I obtain several output signals that I would like to compare i order to know which one is "better", but I do not have any ground-truth or reference.
