Re: Measuring audio quality

[XAVIER ANGUERA MIRO <xanguera@xxxxxx>]

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.

Thank you,

Xavier Anguera
