It does this by throwing out information that its psychoacoustic model deems irrelevant to your perception.

Lossy compression such as MP3 can reach manyfold compression without significant audible difference in quality. You can't do compression miracles like this, so the files are large.

This means that it keeps intact all the data that was originally in the source. A lot of the title contains speech from the game that sounds highly processed to begin with (perhaps even mp3 compressed?) and it could be throwing it off.ĭarthspudius: So whats the difference between FLAC and MP3? FLAC is 'lossless' audio compression. I'm not really familiar at all with this sort of thing and I guess it could be aliasing of some sort, but it could also be that auCDtect is wrong. There's an end to the spectrum around 16kHz, which could well be why auCDtect thinks that something is missing, but surprisingly there is again significant amount of data above 20kHz. GOG.com: Could you check if there has been a mistake with track 13?ĮDIT: Out of interest I took a deeper look into track 13 and it looks strange.

It's significantly less confident with track 1, but that may be because it's so short. So, with the unfortunate exception of track 13, it finds it likely that they are lossless in origin. I haven't listened to them yet, and I certainly can't claim that I can hear the difference to high quality lossy compression, so I ran them though auCDtect 0.8.2 and here's what it thinks:Įric Brosius - 01 - Irrational Games Logo
