AAC 256kbit to MP3 320kbit conversion. I know it's lossy, but how?
- by Fabian Zeindl
Has anyone ever transcoded music from a high-quality aac to an mp3 (or vice-versa). The internet is full of people who say this should never be done, but apart from the theoretical standpoint that you can only lose information, does it matter in practise?
is the difference perceivable, except on studio-equipment?
does the re-encoding actually lose much information? If, p.e., high frequences are chopped away by the initial compression, those frequencies aren't there anymore, so this part of the compression-algorithm won't touch the data during the second compression. Am i wrong?
