Very rough - I'm wondering how you came up with those figures. For starters, AM is not available in stereo - there's not enough bandwidth to encode both channels on a single carrier. Yes there is. There IS an AM stereo. MAny music stations broadcast in it and a few radios still have a botton for it. It's very compressed. |

There's more that goes into coding an MP3 file than the bitrate. Once you know what to listen for, it's plainly obvious which is which. You can do this yourself, btw - encode a track and then play the CD right after it. For instance, on a Steve Morse song, you couldn't hear what type of drum heads or cymbals he was usin at anything less that 192K, while on the CD - it was clear(as each majotr brand has a different sound, just like synths/keyboards/pianos do) The "syrupy" description is perfect, IMO - the syllabance and ring and crispness slowly degrades until it sounds like very clean FM or AM radio if you push it enough. By the time you get to 128K, a CD to 128K side-by-side comparison is painfully revealing. |

Sounds excellent, btw, though not FM quality. |

One of our customers brought one of the WalMart changers in for us to
install and mentioned that it was only 50 bucks... It was a 10 CD/MP3 changer with a nice scrolling dot-matrix display. The changer was 'Durabrand'... I had to go to WalMart to see for myself - Sure enough! They were on closeout for $50.00 (3 left...) David SoundworksCarAudio.com "Masterson" wrote in message ... Wal-Mart sells a FM modulated CD/MP3 6 disc changer for 90 bucks. . Best Buy sells an identical CD/MP3 unit, but branded differently, for $229... What is the name of the two different name brands? |

I agree with the IDIOT salesman....
Since I got XM radio almost two years ago I have only listened to MP3s in the car a couple of times. XM is awsome! Eddie Runner SEVEN SEVILLE wrote: Looking for an MP3 player for my recently acquired truck I went to the local electronics store which shall remain nameless. I asked the the car stereo guy (just last week he was working the television department) about MP3 players and he showed me a few and told me all this riff raff and suggested that I would be happier with XM radio. I was like WTF, i outta just stick with the stock AM/FM that's in there right now. Not much difference between XM and FM you know, they even had a sample in the showroom and you can hear the compression artyfacts. Does any of you own an car MP3 player? Who makes it? How much did it cost? How well does it play MP3's? How does the FM tuner come in? |

Note: once again I have manually removed sci.electronics.repair because
it is irrelevent to the discussion, and because others don't have the common sense to remove it themselves Joseph Oberlander wrote: Once you know what to listen for, Aah...yeah...at this point allow me to point out you are making sweeping generalizations, and backing them up with your own anectdotal perceptions. The fact of the matter is that with a pure source, MP3 audio is superior to Redbook CDDA. CDDA or CDA is in fact only recorded at 174.6 kb/s using PCM without compression. The equivalent to this is a 113 kb/s MP3 file. Given two audio tracks recorded under these conditions from a pure source, you will not be able to tell a difference no matter how good you think your ears are. And believe me, my ears are very good. I know what to look for. The "syrupy" description is perfect, IMO - the syllabance and ring and crispness slowly degrades until it sounds like very clean FM or AM radio if you push it enough. By the time you get to 128K, a CD to 128K side-by-side comparison is painfully revealing. And is this MP3 file generated off a CD, the same CD we are comparing it to? And what codec did you use? Is joint stereo enabled? Obviously under best case conditions an MP3 will be equal to or less than the CD it was ripped from, and generally it will be inferior because of generic codec settings which compromise quality for file size. Do the comparison youself. Find an SACD and rip it to a CDA file, and also rip it from SACD to MP3 @ 128 kb/s. Use whatever you like, but I recommend some Baroque chamber music or light jazz. Now find those artifacts, if you can, and compare them to the CD artifacts. -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.

In fact, I pointed out that if you're listening to an MP3 ripped from a CD, then you cannot expect it to be better than the CD. But if you rip an MP3 and CDA file from the same source material, then the MP3 is capable of higher quality at lower bitrates. CDA is itself a lossy compression as well. -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.

He'll just claim that the TIFF is lossy compression that isn't as good as if you used JPEG to begin with. Lol. BTW - I have taken 24/96 recordings and downsampled them to CD quality and also MP3 and it still was a no-brainer win for the CD. I really did research this in depth as a musician several years ago - and recently re-did the tests this last suimmer to see if things had improved. The quick answer - not really. 128K now sounds like 192K did a couple of years ago, thanks to good encoders, but it's still got miles to go before reaching the level of CD. |

" Riiiight, but once again your IGNORING the concept of the source material. Any idiot knows that a copy of a copy cannot be as good as the original, much less better. So when you COPY the CD which is a COPY of the source material, the COPY you made generally won't even be as good as the CD, much less the original source. The only MP3s you've likely ever listened to were ripped by some hack with a generic codec from a standard CD, and you think this justifies your bull**** observations of the MP3 format. The Alpine plays them back fine, as good as LOSSY COMPRESSED sources can sound. CDs are lossy compressed sources. What do you think Pulse Code Modulation is? And all lossy compression means is that data is discarded - it doesn't even concern itself with whether the data is relevent. Just a question - would you rather have kimber or radio shack cables on your home setup? -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.

FACT: Every MP3 you have ever heard is a copy of a copy, and you think MP3 is inferior based on this handicap. FACT: You can't do math - CDA = 176.4 kb/s PCM @ 44.1 khz. MP3 of the same quality is 113 kb/s MP3 @ 44.0 khz. CD Audio is lossy compression too. MP3 is simply a more efficient compression algorithm. FACT: CDA is NOT a reference standard. Thats why formats like SACD and LP still exist. FACT: You have a tin ear compromised by your pscyhoacoustic perceptual prejudices.

While some people are within that limit, some people are outside. Besides which, sound does consist of frequencies outside of that range. Those frequencies do mix with and affect frequencies within the standard range of human hearing. CD audio also has a limited dynamic range (~110 db) compared to human hearing. While this is far better than tape, it is nowhere near human hearing limits in terms of dR. Realize that CDA is nothing more than a 25 year old lossy compression format developed to standardized audio CD formats and enable the use of CDs for mass market purposes. It is not the best, it is not a reference standard, and it is not better than human hearing. Thats why things like SACD, AAC, MP3, FLAC, SHN, and OGG were developed. Heck, thats why audiophiles still treasure vinyl - its about the only way to get a true to life reproduction of an audio program without being there. -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.

While I agree with the sentiment, I'm not so sure I would call mp3 "far superior" to CDA. Perhaps the standards, yes (and even then, it's not FAR superior by any stretch). But the implementation tends not to be on par, because the same amount of filtering is typically used and the introduction of artifacts tends to be slightly greater in mp3. |

Ergo, you cannot make a valid comparison between MP3 and CDA. They may have not, but I have. MP3 is not as good because CD exceeds the ability of humans to hear(unless they REALLY mangle the processing/mixing), while MP3 creates artifacts that are discernable, if barely. That you can hear this at all while you cannot with a CD - that ends the discussion right there. |

FACT: MP3 is by definition a lossy compression method as opposed to lossless compression methods that exist. As Lizard said, "lossyness" does not necessarily compromise quality, especially when the losses are below threshold. The problem with mp3 is NOT the losses. It's the additional artifacts introduced. While it's true that they can be significant (read: audible), this isn't always the case. |

But dont forget about DYNAMIC RANGE!!!
A CD can definatly NOT keep up with the humans ability to handle dynamic range.... In the case of dynamic range the CD is VERY limited in comparison to human hearing... So the statement below would be WRONG! There is much more to sound reproduction than just frequency response....!!

While I agree with the sentiment, I'm not so sure I would call mp3 "far superior" to CDA. Perhaps the standards, yes (and even then, it's not FAR superior by any stretch). But the implementation tends not to be on par, because the same amount of filtering is typically used and the introduction of artifacts tends to be slightly greater in mp3. Of course there is "in theory" and "in practice". In actual practice, most stuff found on MP3 - even commercially - is a second or third source from the original copy (even when you get a [DDD] CD). The qauntization errors build up in a way that isn't perceived by the ear until the last copy (the straw that broke the camels back if you will). However, its worth nothing that MPEG audio layer 1 was the original standard for DVD prior to the move to AC3. MP3 is two generations improved upon MP1. One of the other crippling factors for MP3 is the inefficiency of most codecs. In order to make MP3 practical on a Pentium class processor (say of about 233 Mhz), most encoders eliminated aspects of the algorithm that efficiently encode the material, such as VBR. By now, a proper codec such as Fraunhofer Pro married with a 1 GHz processor and plenty of RAM is capable of producing true MP3 quality files. Alas, the FGH-Pro codec is proprietary, and many of the free ones (lame, xing, etc) still aren't very good. But I stick to my assertion. If you honestly (added because some people think using crappy decks and homemade CDs you cut on Windows and have your wife swapping out is a fair comparison) compare an MP3 file encoded at 113 kbps to a redbook CDA file, you will not find a difference. Perhaps I should set up a Sound Challenge like someone did for amplifiers ten years ago (but then, there are still fools who believe that they can tell the difference between a coustic amp and a jl amp under the same conditions). -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.

Any idiot who claims that a 'CD exceeds the ability of humans to hear' is not worth arguing with. CDs are far inferior to human acuity.

And what of the 99% of people who can percieve changes loudness in excess of 110 db? That is the limit to a CDs dynamic range. I know a little old lady with a bronco that plays at 174.5 db of SPL - no CD can reproduce that kind of range. You also continue to be painfully ignorant of what PCM does to an analog signal. Most people who listen to classical music are familiar with the insufficient capability of CDA when it comes to reproducing soft passages. Those people prefer vinyl over CD for its ability to reproduce the nuances. You must be crossposting from rec.audio.opinion, because you sure as hell don't know rec.audio.facts. -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.
