On the MP3 thing: neither Apple- nor Windows-generated music files are actual MP3s. Apple's files are AAC and Windows are WMA; MP3 seems to have become a generic term for compressed music files. However, if you're using a non-OS ripper to make them with the actual, far-superior (and patented) Fraunhofer MP3 codec, you can achieve excellent results. However, expect big honkin' files as a result. Both Apple and Microsoft "improved" upon the Fraunhofer technology by getting the same bitrates jammed into files that are much smaller a proper MP3. Quality suffers accordingly, but kids look at bitrates as a sign of audio quality with knowing nothing of compression algorithms or technology. I have a dedicated audio amp (no tuner), an excellent old-timey EQ, a proper component CD player and a laptop. My Fraunhofer-encoded 320kB/s files are virtually indistinguishable from an actual CD unless you push the volume to levels that make the dog howl. From outside. A block away. In someone else's doghouse. Behind a brick wall. My variable-bitrate MP3 files with a max of 384kB/s take up less space but sound about the same; VBR compresses very hard during silent, very-quiet, and very non-complex areas of the music but widens out for the really loud and/or technical topographies. Despite quite a bit of futzing around with them, I have never been able to make an AAC or WMA file sound nearly as good. Literally every song available on iTunes is AAC format, regardless of what the file extension says when you download it. As an added "bonus", there are millions of other non-Fraunhofer-codec compressed files that actually use .mp3 file extension, but with a non-patent-infringing variation on the original. Well, they missed the mark on the CO but nailed the DEC (codec is short for "
compressor/
decompressor"). I actually paid what I considered a hefty fee to have the real deal many years back. It's probably been bootlegged to death now, but I know I've got it and it does make a difference.
The only truly lossless digital music format is the original Microsoft WAV file. It is totally uncompressed and there is no loss of sound quality whatsoever. Of course, the downside is that if you take your favorite CD and rip it to the WAV format, your CD now occupies a couple of GB of space. Burned onto a CD but left in WAV format, you'd need about three CDs to hold one album. Raw musical CD data appears in your OS as a CDA file (extension .cda) and your computer doesn't like those very much. Despite all the things you can do with a CD and a computer, Sony has still got the CD thing by the short & curlies.
No one cares about that, though... they just want to pack as many crappy-sounding songs onto their phone/iPod/max-iPad/whatever device and more means gooder, and even gooderer if it looks cool to boot. I mean, Beats headphones are a Snoop Dogg creation. Why would you buy gear for the reproduction of music from someone who knows nothing about music at all, much less accurate reproduction thereof? I let a longtime friend of mine listen to the same song on her iPad, first with her Beats earbuds and then with my ancient Sennheiser HD433 headphones, which are far from top-level Sennheiser gear. She got a look on her face like God was speaking to her personally... and that was still an AAC file @ low bitrate. I'm pretty sure had it been vinyl or a CD, her brain would've melted. She has literally forgotten what music should sound like.
I was originally going to rant about vacuum cleaners, but ultimately decided that they all suck.
