Weird question about MP3s and Linux
We all know that MP3 encoders have quality controls: that when you encode an MP3, you choose how much of the original to keep, how much to throw away, and how much to "model," that is, how much can be restored to the outgoing audio stream by inserting modeled sounds into the psychoacoustic profile of the stored MP3.
Do MP3 decoders have a similar process? That is, when turning an MP3 back into music, do MP3 decoders make decisions about how much CPU and bandwidth they have, and maybe throw out the lower-priority models, creating a muddier sound?
Because I swear that ever since I turned on RTPRIO (Real Time Priority) for audio processing on my laptop, I've been able to hear more details on many tracks played through Audacious: snare drums rattle more, saxaphone keys click, feet shuffle in live recordings. I didn't think such post-processing was the case, but every once in a while now, while listening to a track, I'll think, "Huh, I don't remember hearing those subtle sounds before."
'S verra strange.
