Sorry if this is easily answered elsewhere.
My question is that in a comparison of lossy-format decoders between, let's say, iTunes and Foobar and Winamp, will the output (edit: of a single source file) vary between decoding implementations? Or is it that once a decoder follows a specified format, all output is equal assuming there are no bugs? This post has been edited by mavere: Jan 5 2013, 00:51 |

In AAC there can be Perceptual Noise Substitution, so I'm not sure I could expect identical output even from the same decoder.
