Here you find the complete folder with the source files and the converts. We have put everything – really everything – in the table below. AAC is more pleasant – quieter – to the ear. It is less harsh than MP3, but somewhat less refined than AAC. Ogg is – according to your author – in between AAC and MP3. AAC sounds better than MP3, especially at low bitrates. Especially at lower bitrates this is very noticeable.īut the differences between the codecs are also striking. Also the ‘space’ quickly fades away because the reverb is partly removed by the codec. It is immediately audible in transient information and dynamics. Is there an audible difference between the codecs at the same bit rate? And is there an audible difference between bitrates? And is there an audible difference between FLAC and lossy formats? Especially a lot of high information that remains audible in the difference tracks. If we take a 16-bit original of the same track, it is much better. You can also hear it very well in the ‘difference files’. We therefore strongly recommend not to do this without any serious adjustments (in advanced settings). We notice very quickly that a lot is chopped off when we go from the original 24 bit to the lossy formats. For this session we will stick with the default settings. Under advanced there are more settings for some codecs.

For AAC (Apple version via iTunes), MP3 and Ogg we do not see this option. When we convert it, only with FLAC do we see the option to set bit depth.
