--Boundary_(ID_BnKySEwKVUIo2onDhsOPLw) Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT 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 Yours, Xavier Anguera ________________________________ Este mensaje se dirige exclusivamente a su destinatario.
