sfogg Posted February 26, 2007 Share Posted February 26, 2007 This might be fun software to play around with. http://libinst.com/Audio%20DiffMaker.htm In effect you make two recordings of something. Say two different pre-amps or an original vs. MP3 copy of the original..etc...etc. The software then basically correlates the two recordings and basically subtracts one from the other so that you listen to the difference between the recordings. In other words you hear only what is different between the two recordings. This is pretty close to what the 2 channel transfer function on my spectrum analyzer does.

Daddy Dee Posted March 3, 2007 Share Posted March 3, 2007 Shawn, Thanks for the link. That is absolutely fascinating. One could then have an objective source for evaluating any change (imagined or real) to the signal, from the introduction of power conditioners or even alternate cabling. Wow. As you mentioned comparing MP3 or CD audio, I'd like to check out different frequency rates for mp3 and compare to losless formats. It would be great fun to compare different power amps driven by the same preamp. Whoaa... just think about comparing any tweak imaginable.

formica Posted March 3, 2007 Share Posted March 3, 2007 Thanks Shawn... Whoaa... just think about comparing any tweak imaginable. looking forward to your comparison posts... [] Actually i'd be curious to seeing two measurements taken without any changes... just to see the variances in the test (PC) system...

Multiple measurements on the same system without changes would indeed be necessary for a valid control. Quote Link to comment Share on other sites More sharing options...

Man, it would be worth the price just to use it for room tuning. maybe I am kiddng myself......... Quote Link to comment Share on other sites More sharing options...

IB Slammin Posted March 10, 2007 Share Posted March 10, 2007 IB Slammin TC. Nice Avatar! Well, the old Frankinspeaker has a different tweeter than in my early avatar. I felt obligated to keep the ugliness up to date. But you,.....you continue to deface that beautiful Mac of yours. Flogging would be mandatory in some cultures! tc Quote Link to comment Share on other sites More sharing options...
