I had another challenging session last sunday, and I surprisingly had the impression I could hear some differences this time. I couldn't really tell I heard anything missing from the CD version, but the HD file just sounded better to my ears. As I don't trust them, I used Audacity's spectrum analyser with both files, and looking at average gain values for some frequencies, they always appeared to be a bit louder in the HD Version than in the CD version. If you look at the screenshots, you'll see it's 4 dB louder for 100 Hz, for example (-32dB is for the HD file, -36dB is for the CD file). I then computed replaygains using foobar2000, and got -6.40dB for the CD version and -6.02dB for the HD version. So, downsampling 24/96 to 16/44.1 with SoX seems to lower the average gain of the 16/44.1 version a little bit. Is an average 0.38dB volume difference sufficient to be heard? I can't tell for sure, but thought it would be worth mentioning... +-------------------------------------------------------------------+ |Filename: Shields-16.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=11479| +-------------------------------------------------------------------+ -- sebp 'Last.fm' (http://www.last.fm/user/sebp) ------------------------------------------------------------------------ sebp's Profile: http://forums.slimdevices.com/member.php?userid=11768 View this thread: http://forums.slimdevices.com/showthread.php?t=85879 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
