Why is it that we download MP3 files and not CDDA files? Would a CDDA file be too big to dowload like a Wav file? Also, isn't one song in Wav format something like 300 mb; how is it then that you can fit an entire album on a 700 mb CD? thanks for bearing with me, I'm trying to figure this all out.

when u burn an AUDIO cd, it goes by length in time, i.e. a 74 minute CD will fit say 10 .wav files or 10 mp3s. a DATA cd however, will hold 700 mB of data, either 10 .wav files @ 70 mB each, or 10 .mp3 files @ 70 mB each. the difference is that a .wav file contains much more information in that 70mB (roughly 7 minutes of audio) and the .mp3 file is compressed (roughly 70 minutes of audio). hope that kind of made sense.

as far as i kno, nobody transfers file in the CDDA format...at most in a .wav or .aiff format.

and to answer your earlier question of burning .wav files as an audio cd compared to store bought cds, you can't replicate it perfectly. store bought cds are pressed at a manufacturing plant where they make masters of the file and are used to "stamp" the cds. this has to be done to ensure maximum data transfer from the audio master to the cd that you get in the store. burning cds at home is only done through a laser in your burner that burns the data but is prone to a LOT more errors.

Originally posted by VIO you're right. no plug-in can ever restore what's been removed for the compression technique. however, it can produce and fill those missing frequencies. it uses a combination of effects and enhancement logarithms. of course it won't sound like the original recording once you run it through the plug-in. it will however make it sound pretty damn good as compared to the mp3 un-enhanced version, especially in the low end and high end frequencies. enough so that you can play it in a club and it will sound good. you see once you apply effects to say an mp3 that has nothing below 25 hertz, which is ultra low bass, even though there is nothing in that frequency range the effects you apply will still produce results in those ranges if you set them up to. things like flange, bass enhancement and especially chorusing. a spectral enhancer just takes that 2 steps further. there's a lot you can do to an mp3 to make it sound good if you actually know how to produce, downmix, master and properly use an eq. hell, i've been doing stuff like this for years and i'm still learning all the time.

any chance of a small sample of an un-enhanced vs. enhanced mp3 file?

Originally posted by VIO you're right, i didn't write that post correctly. both the wav and cdda are just different implimentations of the "pcm" format and are virtually identical. this also holds true for the mac aiff files. while cdda can only be encoded using pcm, wav and aiif can also be encoded using dpcm and adpcm formats. both of which are a compressed form of the pcm format. nice catch qfx. way to keep me on my toes! cheers.

hey VIO was checking your websites in your sig and noticed you were from St. Louis
thats where i'm originally from. but now i'm living and going to school in LA.
where have you spun there? i used to go to quite afew raves there when i was in HS.

If I understand everything correctly we would not be able to hear the difference between an enhanced and an un-enhanced MP3 sample. The difference could only be heard on loud systems…

hmm used to give some stuff to few djs at the clubs in my area. pretty good sound systems in those clubs and i could never tell...







GIVE TRANCE A CHANCE....

CDDA and .wav files are both approx. 10mb per minute where as mp3s at 128bit are approx. 1mb per minute.

no, but i can get you a copy of the plug in. you see you can't apply the plug in to an mp3 file. you need to load the mp3 file in an editor like wavelab or soundforge. you need to convert it to a wav file. then when you eq it run it trough the plug in, etc. you need to save it as a wav file. if you turn around and save it as an mp3 you're going to re-compress it and null the enhancements you just made.

i've headlined at velvet and deep six and i've played the oz as well. i've played a few parties/raves in st. louis but not too many. i mainly stick to the clubs. la la land entertainment hosts a night a velvet every week. i actaully live in central illinois not too far from st. louis. my agent/la la land ent. is in st. louis and that's where my family is from. i play all over the place though. i have yet to play in chicago but my agent is working on that. did you ever go to the red or blue raves or any of the boogie knights parties?
