(Free) Software to analyze HD and DSD tracks? 2018-04-25 16:36:57 Hi,I performed countless blind tests on myself and finally gave up (re-)buying more expensive HD tracks. To save some space, I want to convert some of my 1-3 GB albums to 44.1 or 48/16. For that I want to uncover all the badly done masters and cut off all the information that is only noise. (Backup the original downloads on an external drive and forget about them.)I guess the best way to do that is to use a spectral analyzer. Then, look at the information that is happening above 22 kHz and try to see whether it's actual audio (should be a downward slope) or noise (non-dynamic and constant peaks).To some extent, Audacity is sufficient. But it limits the analysis to 109 seconds and I noticed that the beginning often has less reach so I have to search the file for the part with the most amount of data. Also, it does not read DSD.BTW, I'm on a Mac so unfortunately a foobar2k plugin wouldn't help me.If I got anything wrong, please let me know. I am willing to learn!Thanks!
