Which audio codec are you people using when ripping cd’s?
I used wav but the size made it not really fitting on my phone (60GB) I switched to FLAC.
Many people I talked to said that CD’s just use mp3 codecs in the First place.
Unfortunately, it seems you have a really bad misconception as well.
Sorry, no, files (be it MP3 or FLAC or MP4 or whatever) do not degrade over time. Not one bit. Yes, storage devices do degrade and ultimately break down, but that does not result in MP3 files “losing 7 to 15 kbps per year”. Digital files are like that—digital. They don’t suffer the same degradation like vinyl where each playback damages the grooves and looses definition. Digital files are a bunch of zeros and ones (be it MP3 or FLAC or whatever) and it’s either those bunch of numbers makes sense to the player (as in, it plays) or not (as in, the player shows an error saying it can’t play the file).
What you have experienced as “degradation” probably isn’t the result of files degrading over the years. See, when MP3 was invented, the early encoders produced relatively bad sound quality for a given bitrate. They just can’t pack that much information into 128kbps without affecting the sound quality. Over the years, many countless improvements were made to MP3 compression technology, and modern software like LAME can produce really good sound quality even at relatively low bitrates. That makes old files encoded using old encoders sound worse than new files encoded using new encoders at the same bitrate.
MP3 doesn’t even support 16kbps, so I can’t imagine your storage device delicately removing bits from your MP3 files to reduce the bitrate without corrupting them, since storage devices can’t even see the boundary between files—it only sees all the files as one huge string of numbers without any sense. Also, I can imagine your MP3 file shrinking in size every year if they do lose bits over time. Many filesystems also offer integrity checks on files, so your computer will alert you if something unintentional changes on your storage. Even some Linux filesystems will show an error if a single bit unexpectedly changes on one of your files.
Wherever you read that misconception, please don’t believe it. Digital files are not affected by quality degradation, and it’s either they play, or they don’t play.
Hopefully you take this as a friendly message, and if this has been a joke and I’ve been whooshed, then you had me very well.
Yeah, looking back, I’ve probably been whooshed, but I’d be very happy if I can at least help prevent someone from unknowingly falling for it. I’m a software developer as a profession, and I can’t take false misunderstandings about digital stuff like this. Also as a digital audio enthusiast, I understand that digital audio is superior in every way at least theoretically but I also accept that some analog formats (like vinyl) have better mastering and can sound better than their CD re-releases.

I can’t tell if I’m being double-whooshed, but ‘rotational velocidensity’ is a very old meme. Your post is fully correct though, so good job!
I think it is just a joke, because of course IDE is still better in quality Preserving than Sata.
Make sure to only transfer MP3 files to your memory card using the serial port—USB degrades the sound quality by around 12 kbps per transfer /s
