Michael C - 26 Mar 2006 04:48 GMT
I'm thinking of switching from using CDs in my car to SD cards or something
like that. My wallet of CDs is pretty big and doesn't fit in the glovebox so
slides around on the floor plus half of them don't work too well. I was
thinking of buying a few 1GB SD cards ($50 on ebay) and copying selected CDs
onto them. The only problem is I don't want to lose quality, I had a CD in
the car of songs that came from MP3s and they sounded really crap. Is there
a compression format that sounds ok? Is the microsoft or apple format better
than MP3.

Thanks,
Michael

Blech, I have the problem that two of my favorite CDs (CD-R media) with
about 15 tracks or so, crap out with ERROR-04 in the 'lux CD player (A
Sony), at around track 3 or so when driving over speed humps, etc.
Bought ones tend to be OK.

Any data loss compression is bad, it's just a matter of what is
good enough.

Fair warning.
Visit your dentist.
You Hi Luxen owners are gold to dentists for replacement fillings.
Or is that Mercury. Or somethin.

You heard the stories of alchemists trying their arses off to turn
Quicksilver to gold?
Well, the dental profession have managed it in spades.
Pity the crap they use will kill us all early.
(Sardonic note: So far it's killing us late enough that we've finished
being the 'earners' by then. So, the sh.t won't hit the fan until

Probably a couple more chemical additives in food might tip that
balance.) :-)

Prolly good advice, I think I have a cracked off tooth
at the back lower left (fairly sure I do). Heck, Im a
redneck though and won't go near 'em. Ceramic fillings
might be the go for those dentistes that know about them.

Meh, at least the Ulnar nerve thing is getting back to
normal tonight.

Just fork out around $4k per tooth and go the implant track, better than
your old teeth they say.

(Not sure that Id spend $120oddK on teeth though, you can buy a lot of soft
food for that sort of cash.)

If your dentist isn't putting white fillings in your teeth go somewhere
else. I believe some dentists are using the old techniques but there's
absolutely no reason to do this.

just go get a car cd mp3 player and load up mp3s onto the cd-r or cd-rw.
Much more common than car stereos that take sd cards and probably a lot
cheaper solution. easy to have a few cds full of mp3s in the car.  If you
really need heaps of storage, there are also some affordable stereos that
will play mp3s off of DVDs which hold heaps of music.

mp3s normally aren't to bad quality if you encode them at a reasonable
bitrate. Not really any noticeable difference from the original cd.  If
yours sounded crap, it was probably burned from crap low bitrate/quality mp3
files

That is one option although CDs are pretty big compared to an SD card and SD
cards are not mechanical at all and much easier to copy music onto with the
option of changing later.

I believe they where encoded at 128kbps but you could be correct in that
they were recorded incorrectly. I've had a listen to a couple of other
128kbps mp3s and they sound ok on my PC although I can tell they are
compressed. I'm no audiophile so would probably be happy with just a
slightly higher bitrate mp3 but was wondering if the MS, apple or sony
format is better.

*.OGG files are better than MP3,ogg players will not be an easy find in
Australia if at all,still a lossy format,

http://www.doom9.org/faqs.htm

WMA is supposed to be a non lossy format,possibly more to your liking
when playing with SD cards and custom devices.
WMA is bound to be supported by a car player,custom device?

Most car MP3 players will also play WMA files

My Pioneer P4650MP unit does
I can't hear any real noticable difference between the WMA and MP3
versions of the same song

I rip my MP3s at 256kbs so they usually sound quite good, the drawback
is that you can only get around 100 songs on one disk

Magic Mushroom Farmer - 27 Mar 2006 04:26 GMT
I think if you amp it right up,clarity will prevail with something like
WMA,not that it matters much when bombing around the country side with
wind noise,traffic,noise and other interference.
I ripped some Satellite radio streams down to 128kbs MP3 and was quiet
impressed playing them on a computer.
None Entered - 26 Mar 2006 10:31 GMT
I feel that I can tell a difference between 128kbps bitrates and CD-Quality.
Seems to lose some Highs & just subtle sounds.

I always rip at a minimum of 160kbps, and sometimes higher. All my CDs
basically are "backups" nowadays, and I too have been thinking of another
system to store more, even to the point of rigging up a computer under the
seat with a 200gb harddrive, but then it's the interface and having to buy
an LCD to use. Anyway, I'm sure there will be a million options in the next
2 years, so for now I'll just stick to the 15-20 songs per CD.

On another note, is it just me, or do all the major radio stations share the
2 CDs of songs between each other?

I've been listening to 91.5 lately just for a little bit of "difference"

If you are happy with 128kbps then you aren't very discerning since that
kind of compression completely munts the reproduction from the original
source. Try 192kbps to reproduce something approaching the quality of the
original source.

I personally think WMA sounds better then MP3, and OGG is certainly better
but not as well supported.

Did all our CDs at Q10 ogg. Just play 'em off the hard disk. It's a real
shame ogg isn't supported by in car CD players.
8" woofers, 5" mids and motorola tweeters with 2 x lm380 IC amps (soon to
be lm384) SB live sound card, alsa drivers, sounded OK with Q6 but redid
them all at Q10 and it is noticeably better.

Any mp3 that is at least 128kbit and 44000hz will be indetectable from
a normal cd to the human ear.
Mp3 is the best format because its universaly compatible and sounds the
best.
I suggest you buy an mp3 player and transfer all onto disks full of
mp3's
And dont buy an SD card before making sure you can plug it into your
current cd player.

That's simply not true. Experts can *easily* pick 128kbps mp3s in blind
tests.

I suspect it's not.

I'll have to get a CD player with an SD slot.

You'd have to have pretty bad hearing to not be able to pick it. Even
encoded at 320kbps MP3 is audibly worse to audio CD.

Oh, and for the OP - SD cards may not be your best bet. They have a limited
read/write life; they will just die one day and that's the end of them. High
quality single-layer memory cards will give you 100,000 cycles; cheaper
brand multi-layers might only give you 10-15,000 cycles.

MP3 CD would be your best bet; encoded at 256 or 320kbps for good quality.
Sure, CD's are big these days, but you'll fit 100-200 songs on one CD
instead of 20.
Or you could just go down the Ipod road, fairly common these days.

Could always go the road of DVD audio,fairly cheap these days if
imported from asia(ebay.com.au)

Crappy mono-sterio things....little sister got one of these and spends
all day encoding DVD's to fit on it...what a waste of time,not only are
they compressed they are veiwable on a 2 inch LCD....arrhggh hate em.

10k cycles would be plenty still. By the time I play music from the same
piece of memory 10,000 times, terrabyte cards will be available and I'll
want to update it anyway :-)

Depends what you mean by "good"( err, "best"). It's good in that,
because it contains DRM, the record companies are happy to sell you
music in this format, meaning you don't have to buy an entire album
for one track. In terms of quality, AFAIK it's not significantly
better than any other lossy compression system. If you're just looking
at ripping your collection of CDs, I personally don't see much
advantage in any one format over the other, and think it depends on
what hardware you currently have, and the format of the music you
currently have. Clearly, if you have an iPod full of Apple format
music, you'd want an Apple format compatible player (or an adaptor).
OTOH...

I have an ipod shuffle which is really good but it's only 512mb and probably
wouldn't sound that good plugged into the car. I think a lot of these units
modify the sound to compensate for weaknesses in the headphones (such as
adding more bass).

I did a bit of a search and it appears the MS format is the best that is
likely to be supported and 96kbps is meant to give a good quality sound.

Does it have the iPod accessory "port"? If so, you can get a
non-equalised "line out" adaptor.

Ah - WMA format. You're not falling for their "Plays for sure" slogan,
are you? Not sure it'll actually play on an iPod - something you'd
likely want to check, since iPods don't play MP3s either. Oh, and
96kbps in WMA is roughly the same "CD Quality" as 128kbps MP3.

I don't get these DRM people - you can burn a song onto a CD x many
times, but not more??? Err, really guys, you haven't thought about
that, have you? It's not like anybody would rip the newly burnt CD
into a different, non-DRM format, would they? No, of course they
wouldn't.

OT (but not much): Just as an iTunes store will give you another copy
of music you've payed for if you lose it due to HDD failure or
similar, did you know that most record companies will replace a CD
that's accidently damaged for you too?

It definately won't play on an ipod but I wasn't planning to.

Yes they do.
