Well, actually it was that long cymbal sounds “fade” quicker and just sound different with lossy music.
IIRC I distinguished an mp3 encoded by iTunes with bit rate 192 or 256 kbps from its original in Apple Lossless (both played on same cheap acoustic system). I probably should test with AAC or Ogg, too. Although I have a feeling that it's pretty much impossible to keep intact those rich in high frequencies cymbals while keeping compact file size.

You're much better at controlling your mind. =) After I once verified that the difference is audible even on cheap speakers, I can't switch back to lossy formats. It means constant wondering if that how it's supposed to sound or not…
That's, by the way, why Apple's idea of having ‘Mastered for iTunes’ label[0] IMO is worthwhile—at least you can be sure that mastering engineer listened to it this way. =)

- TylerE 15y agoIt's certainly true. Ogg is far less audible than mp3 - it's actually very decent at bit rates as low as 64kpbs.
- cbr 15y ago"I distinguished" Was this in a blind test?
- goblin89 15y agoPlease refer to my comment above[0]. Yes, it was a blind test. The person helping me might've looked up bit rates, so it was not a double-blind experiment, but I could not (nor did I want to) see what's being played, and relied only on hearing.

- pja 15y agoMight be interesting to try AAC or Ogg Vorbis & see if they're any better. In these days of ever increasing cheap portable storage carrying a bunch of flacs around isn't quite as nuts as it used to be of course. (Cymbals seem to be a particular bugbear for mp3 encoding; cymbal-heavy tracks tend to suffer the most from obvious encoding artifacts once you know what to listen for.)
