Re: Measuring audio quality

Dear Xavier,

Source enhancement or, more generally, source separation algorithms may be evaluated via the energy ratio metrics in
(scroll down the page) or the perceptual metrics in

Dear all,

I am working on an acoustic beamforming system that, depending on the
input parameters, will output a single audio signal. I am not very
familiar with the signal quality area and would like to ask you for
advice as to how to measure the quality of each of the signals. Note
that I have already tried some toolkits available online that give me
some SNR-related measure, but I do not find these consistent across
several signals in my dataset. Maybe some sort of comparison between my
output signals would give me better results?

Thanks in advance for your advice
