Hi all
Im a bit tired and not feeling well, but this thread has got my attention and I thought to mention some things which seemingly have been passed over somehow and Im unable to let go of just now.
Indeed there are several immediately notable variables taking place here.
DTC corrected a couple terminology and format ones regarding the diffs from reduced file size and compression visa vi FLAC.. ALAC.. and WAV/WAVE. None of which are compressed
albeit some are indeed reduced in size.
It seems to me the more noteable issue is the ignorance or dismissal of the amount of jitter introduced by the CD or DVD rom in the personal confuser being used, right off. Not to mention the varying types or brands and models, from machine to machine, system to system. Their ages, use, ripping speeds, cpus, bus speed, etc.
Also error correction vs. jitter. Naturally they arent the same thing. A spec or scratch on a disc vs adherence to a specific rotating speed and reading accuracy.
Only just recently did Jax2 mention the use of any player aside from iTunes
and which version of iTunes
BTW, is/was being used?
All of this is far from anything resembling scientific experimentation or analysis. In such instances there must be controls. Identicals. Consistencies.
Im surely not taking anyone to task about that bit either, just being as objective as Im able to in an effort to make some sense of the controversy here.
Finding results that vary from one members trials to another therefore isnt too eye opening IMO. What I do find remarkable is any fact supporting similar processes being followed and yielding similar results
. Given all the aforementioned variables just noted, and indeed there are others I have not pointed out. Such as burning these files back to CD
what CDRs were used? At what speed? Did everyone use the same CD ROM or combo drive? Transport? DAC? Audio rig?
Of course not. Far from scientific
but its Fun
just not definitive.
Another thought to throw into this is the plug in aspect. ALAC (m4a & m4p) FILES CAN BE PLAYED BACK USING PLUG IN CODECS other than the proprietary ones afforded the user by iTunes, Quicktime, MC, FUBAR & EAC. Albeit iTunes doesnt allow for such a thing. Other media players do however.
If you would care to improve upon the quick time engines handling of the ALAC files (m4a) try the Direct Show filter, or base plug in, available as a free online downloaded item.
Theres a bunch of algorithms out there, just as there are several mp3 plug ins like LAME & MONKEYs, etc. Although the latter are based on the Frahauffer codec design, they arent exactly the same. The AAC file type adds yet another layer to the compression making it an mp4
vs. mp3.
Also what driver are you all using? ASIO? Which one? BTW were all the interfaces as well, identical? Coax? USB?
Merely opting for different aSIO drivers can and does change/improve the sound.
Ive been playing with, trying out, changing file formats, pcs, codecs, media players, sound cards, DACs, hard disc formatting, pc cooling, isolation, power line filtering/conditioning, differing ROM drives, ripping speeds, etc., etc., etc., for about 8 + years now. Just recently did I bite the bullet and decide to go HDD digitally based with my source, for 95% of intended playback.
Heres what Ive found out so far
. Everything matters.
Change something
something changes.
Changed the media player, the sound improved or just changed.
Same thing with all else. DACs, interfaces, media players, plu ins, and yeah
file types. And depending upon the file type and/or player, (predominately) things could be well improved right then and there!
Even in a one box player rig, the CDR does make a diff when compiling a CD.
Any file format one wishes to use can be optimized for playback in ones system
. Yeah
even mp3. media Center offers the LAME & FLAC CODEC as standard equipment for ripping. It also uses error correction but MC calls it secure ripping instead. FUBAR & WINAMP allow plug ins too.
If WAV/WAVE sound best to you but you want the art work and ability to transfer them to another computers database, and keep tag info
try out ey the WAVpack codec
it incorporates tagging info while retaining the uncompressed WAV file type as the media audio format.
The attraction of itunes is great for sure as it is way easy to use and sounds pretty good straight off
but its no end all be all in media players. If youve tried a few then you know. If not, then you should try a few other players.
Another consideration in choosing a file format is versatility. Cross platform playback. You might go with a different platform or OS down the road perhaps.
Size however, is becoming less and less the problem
. And tagging info is mighty important too. Art work or no art work.
Another item is bit rot. Leaving bits on a magnetic disc for extended periods allows for decay of the file, and consequent loss of some resolution, or gasp! Loss of the file due to its corruption. Just copying the folders to another partition on the drive or to another hard drive periodically, will overcome that pitfall. Annually works for me.Sooner aint a bad idea neither.
What accounts for why we hear or dont hear a diff from one file tuype to another is IMO a moot point. Especially given the degree of diff one might hear.
The more important aspect I feel is which file type is best for you, and what can be done to optimize it for playback in your system
now
and down the road.
Waffling or stressing over a few MB or a 5% gain in resolution, is silly when you get right down to it.
Think more so about the new & upcoming formats of higher res file types
I suspect these are going to be inherently larger anyways. We all will want to accommodate them, right? Sure.
Im personally happy with ripping CDs via either iTunes, MC, or EAC. The latter ones I like a bit more for the resolution and detail in the end product. Between AIF, WAV & FLAC, Ill go with FLAC OVERALL. Rip to WAV with iTunes and convert if needs be.
AS the J River MEDIA CENTER sounds best to me I seldom if ever use iTunes any more.
There again however is another issue
conversion. Just how jitter free and error free is the conversion process and the converted file? Was it cached and checked for accuracy at any time in the process?
Beats me. Dont care really. I try not to convert anything anyways.
If you rip CDs right out of the packet, error correction isnt a major deal
jitter is. Funny how as degrading as jitter can be in audio playback its ignored with the software rippers, & ROM drive technologies, themselves.
I say use which ever file type you like or need, depending upon your converter/hardware, and improve upon the sound tangibly, tactily, with better devices, cabling, etc., etc..I doubt seriously anyone here who is using whatever file type is missing out on much, given the looks of their rigs
or at least from what Ive seen thus far.
At least think more about the DAC - CODEC or player being used, than the file type (lossy or lossless) itself. Youll be better served. IMHO
