Just have a couple questions: is this PC rip, and what does 15khz roll-off mean?
And yes, its from the (gloriously AO-rated) PC game. Since the files were 30khz 16 bit, there are no frequencies above 15khz (for comparison a 44.1khz WAV, CD format, goes up to 22khz in both channels). So the frequency response is lower than a lossless CD. But the files that were originally in ACM format were 48khz 16 bit, so their frequency response is a lot better – even my VBR MP3s go right up to 22khz on these 😀
It’s been years and no word about the possible sequel, but I think someday Rockstar will revisit the franchise and hopefully create another dark mind-fucking adventure ^_^
