What's the compression standard that's closest to CD quality?

wow, that's cool, any idea what's the compression rate like? I'm considering skipping the CD player hehe....but then would the IDE/SATA cables from CDRom --> HDD cause quality loss too? need special IDE/SATA cable?

 

is there any standalone HD player that's able to play these format? a bit hassle to go through a computer just to play it.....

if you use EAC with error correction all the bits should be transferred properly.

 

You have to try out for yourself which MP3 compression rate sounds best to you - some people can;t tell the difference between 256kbps and CD, some 320kbps. If you can't tell between CD and 256k, then its fine to use if you want to save space. however if your downstream components become more revealing this could be exposed.

 

Anyhow, I'd recommend FLAC, but any lossless compression should do fine.

the compression is almost 50% on most of my audiocd... the file size is about 250mb for a 50mins CD...

 

i didnt use any special sata cable to compress... and seriously i cant really hear the difference too.... i think apple support FLAC but not ape...

 

for ape, u can install winamp with the plugin (usually comes with it) and you can decode on the fly while playing back

Good that you cannot hear the difference in a lossless format :)

Otherwise there are so many lossless formats it is diffidult to count:

APE

Apple Lossless

FLAC

WMA Lossless

Mpeg4 Lossless

Dolby Lossless

MLP

... the list goes one

discussion only on ripping portion and not playing. :) too many variables.

 

IMO don't really bother with the cables, but a good PC cd/dvd-rom helps cos of error correction, etc. there are lists of recommended ripping cd-roms. also, i think there are utilities to ensure that you have a 100% rip, but to me usually 98%+ is good enough.

 

FLAC is my recommendation also.

however, in some of my cds, its same size as wav, so sometimes i don't bother with the conversion. there is a big difference even vs variable bitrate mp3. i think even my novice friends find out.

 

Wav does sound slightly better than FLAC to me in some setups, but i think this is because it may require less processing on the PC/processor front, rather than any fidelity issue. most setups there isn't a difference.

So you hear the difference in processing power too?

AMD or Intel sounds better?

well i don't use a PC for playback most of the time.

i use a squeezebox which has limited processing power, served from a NAS with also limited processing power. just to tell u how jialat, it takes me 1hr+ to refresh my music list.

 

for native formats, the files are passed to the squeezebox to play automatically (hardware), but for non-native format, i believe either the server needs to convert first before passing over, or some software decoding is done by the sb (dun remember which now). of cos all this is theoretical, but i feel there is a slight diff.

 

anyway thats why i say most setups there is no diff, but there is a possibility.

wow, looking back just realized I posted something which I am seriously looking at now......heheh.....

 

out of the sudden, I happen to have a few ape files with cue sheet. I can't get these CDs anymore and it took me many weeks to kop it from the internet......they sounded so great!

 

I am thinking of converting them to CDs, FLACs or MP3s, however, most of the files I have is single APE files with a cue sheet to indicate the tracks info, how can I separate them properly? any idea?

The CUE sheet has information on how the tracks are separated. There are many programs that can read CUE sheets and burn audio CDs. Even Nero can do it. However my favourite program is called "burrrn", can find it at www.burrrn.net. It can convert flac, ape and other lossless codecs to audio CDs.

i am very curious, if I were to rip the CD to ape or flac, and then use this utilities to recreate the original CD, how much quality loss are we looking at? Assuming there is no loss at the ripping process (would there be any) ....

In digital world, nothing is loss if the CRC check are within limit. In real world, ripping audio to lossless format only maintain the bits and bytes in order but not counted the jitter during ripping and I believe the audio CD allow to have certain % of error. That might contribute to the ripping/copying audio quality.

 

This also reminded me to look for the answer about the digital/coaxial output from CD transport the different between the optical and coaxial. Anyone found the answer?

yah, I posted something like that earlier.....but have you tested both yourself? a lot of time, people will say no diff coz your entry/mid-range equipments is not tok-kong enough to spot the diff.....
