Possible phase reverse (invert) bug?

Post by Usabell »

Hi there! I just stumbled upon something interesting. If you take an audio file and open it in Amadeus, copy it, create a new track, paste it there so it is exactly the same, then phase reverse one of them and mix both of them into a new file, there is still signal left, even though it should be total silence. It can be made audible by normalizing. I think there is a 1-bit shift or something in the phase reverse code. I found this out because I was going to make some scientific analyses with audio differences and tried this "dummy" test on the same audio file to see if it creates silence, and voila - it doesn't. Just thought I'd share this so it can be fixed later on :)
