I've been looking for a way to objectively evaluate sound quality all my life.
I think this software is a perfect comparison tool that integrates all elements of all verification methods.
However, my personal knowledge is poor and I am not able to fully master the software.
I want to use this software to quantify how much the original sound source (flac format) is encoded into various formats and how much it deteriorates compared to the original.
The simplest way to compare the match rate with the original is to look at the past logs and recognize that the higher the negative value of "RMS of the difference of spectra", the higher the match rate.
Do you agree?
Also, is the 60 day usage period for this software still valid?
There's no trial period -- the software is free for. as long as you want to use it. Donate only if you feel you must, I'm not demanding donations
RMS of the difference of spectra measures the difference between two spectral averages of the two waveforms. It's enough to judge whether there's a significant deviation in frequency response only. Use RMS Null difference for an overall measure of "equality" that includes timing, amplitude and frequency information. If you want a measure of the "audibility difference" between two files, take a look at PK Metric in DeltaWave.
