Thanks, swiv3d. I am aware that I'm not going to add data to the compressed mp3 file to bring it, let's say, to the level of a wav file. But I'm just wondering how the DSP enhancements work. And do they do enough to bring it to a level that is sufficiently fuller in sound? My ears are aware of the surround-field enhancement as well as the effects of the equalizer settings, for example. But what about the boost of the output from 44,100 Hz to 96,000 Hz? How does that work? I read articles that assert that nobody can really tell the difference anyway. How does JRiver produce such an enhancement? When I listen to the resultant tract after my DSP changes, it does sound better to me. But maybe I'm just kidding myself. My hearing is not all that discerning. I like to record the result and keep the track so that I don't have to reset all the DSP categories every time I play the song. I guess it all does come down to whether it sounds better to me, as you stated. I record using Adobe Audition, and I use the What U Hear setting in my sound card to record. Is my sound card recognizing 96K Hz even if I'm not? Or is it some kind of simulated 96000 Hz?
