A year ago I ventured into the HD music scam. High resolution music: offering many times more resolution than a standard CD. Must be good, right? More resolution is better, right? Awesome, they have Michael Jackson's "Bad" album! One of the best-selling albums of all time. This must be in my music library! *buys 24/48 version, thinking it's better* Nope, nope, nope, nope, nope, nope, nope. This was probably one of my most regretful moments in my audio journey. A: Loudness war (I had no idea what this concept was at the time) ^ you can quite easily see that this was remastered as it has a clear line as to where the music's dynamic part stops B: CD-quality origin(?) ^ 44.1 kHz sampling rate is the Red Book standard; Nyquist sampling theory states that the maximum frequency obtained is half the sampling rate (44.1 kHz / 2 = 22.05 kHz); you can, again, easily see that the cutoff frequency was ~21 kHz here and there's added stuff above it in some parts of the song C: Clipping. Clipping as far as the eye can see.... ^ words need not to be said As they say: garbage coming in, garbage coming out.
