MP3 players

Here is the deal with MP3. It is lossy compression getting its original data from CD. Most every MP3 out there was ripped from a CD and then had a lot of data thrown out. You lose info. You might argue that the data lost is not important, but I think most audiophiles agree that data loss is never really OK. MP3 primarily loses data about the high frequencies and low freqencies. As for the bitrate thing, that has nothing to do with Napster. The idea is that when someone creates an MP3 off of a CD, they can choose the fidelity level. 128 bit is normal but it can be higher. I think that you might be able to do MP3's that are nearly lossless, but so few people make such high quality copies that you will really only encounter those if you make them yourselves. Here are my two suggestions. One is that there is a new piece of hardware coming out that is detailed on Stereophiles website that takes the data off of a CD and stores it on a hard drive with variable compression. You can use that system set to lossless or near-lossless compression and achieve an effect close to that of an MP3 player. Otherwise you can buy the home audio MP3 player that Dell is going to release and just deal with the problems.

I agree with Nhorton that mp3 is a lossy scheme, but so is AC-3(dolby 5.1),DTS, and all other forms of mpeg including the dvd format. What I meant by downloading the highest bitrate, was that it should sound better because it uses less compression(higher bitrate) to make the file. As far as my ears can tell, I have heard some pretty damn good audio coming from dvd. Sure mp3 is not on par with SACD or a 96/24 audio dvd, but it isn't supposed to be. A cd has a bitrate of somewhere around 705 kbits per second(44100hz * 16 bits). A mp3 encoded at 320 kbits is just under half that , and 128 kbits would be about one-fifth. If I am not mistaken, DTS and AC-3 can compress audio up to around one- eighth and are usually in the one-fourth to one fifth compression most of the time. So just to say that because it compresses the file is not a valid enough reason to say that it sounds bad. It has to do with the quality of the encoding and decoding process. If someone has a inferior codec in their computer, yes the reult will not be good, but if it is a good encoder(most people use the Fraunhofer(the main member of the mpeg consortium)codec. If that is the case most mp3's should be of fairly high quality as I'm sure Fraunhofer wouldn't the mpeg format to have a bad reputation for quality. Anyways, there is a new player on the market that claims to be better than mp3 so it might not matter for to much longer. The new format is called Vorbis and it creates .ogg files. It can use either variable or fixed bitrates. It is also a lossy scheme, but they say that uses better acoustic models to reduce the damage to the sound. It is also able to support multiple channels and can use bitrates from 8 kbits to 512 kbits. For more info go to www.vorbis.com The only way you will find out if the mp3's you download will sound good or not is to just play around with it and see what your ears tell you. I think that if you download the higher bitrate files you will find that they sound pretty good.

WOW. It sounds like you have allot of expierience here GRUMPY. Thanks for all the great info it definately has got me more interested and hopefull. I'll look into it some more. Also I've seen some MP3's on napster as high as 300kbps so I think things are really starting to move. Hey one day they may be able to go straight off the masters or be able to download from a high quality digital master and beat out everyother format with some super high bitrate and sampeling frequency. Who knows. Then we can say we were on the boat before any audiophiles would give it a chance.

You must not be aware of all the lawsuits against Napster and MP3.com. There is simply no way you'll have a higher than (or equal to) CD quality recording you can download off the internet for FREE. "From the original master tapes"...Just isn't going to happen. It may be that people stop buying aluminum CD's, and instead pay for downloading their own (in the next 10 years), but I wouldn't bet on that either. CD as it exists now will be around for quite a while longer, and if you shop hard enough, you can find many for cheap. If you like classical, many of the Naxos titles sound excellent, and they are only $5 a piece.

Actually Carl, I am aware of the lawsuits against Napster because I was banned from using it for supposedly having Metallica in my computer. I already own all of their discs including the DCC golds so I had no reason to put in my computer, but I was banned anyway. Thanks to some other users, many web-sites posted ways to get around it, and thats what I did. Actually, you're statemanet about not being able to have "from the master quality" is incorrect. The main reason that peolpe use mp3 format is because it takes up less file space and shortens the download time. You could just as easily transfer .wav files, that are true uncompressed digital files, but it take much longer to download and a lot more file space. A lot of music is actually recorded, mixed, edited, and stored in computers without ever using any tape, digital or analog. Alan Parsons is one of the main persons doing this. His album Try Anything Once was completely recorded using his computer.
