Kbps ???????

56
128
196
320


where does 1411kbps fit in?

it don't when you're talkin about mp3's

it might be a VBR (Variable BitRate) file. Which would explain the odd numbers... Winamp is notorious for doing this.

Even a VBR mp3 file would never hit more than 320kbs.... sounds like another format or wave file to me...

What are you trying to figure out here?

Sounds like you're using Serato

My mp3s are all at 192Kbps and gain at 95db.

1411 is a PCM WAV file :)

Isn't a 1,411 kb/sec WAV file --- IDENTICAL in content to a Compact Disc?

I've been operating under the assumption.......based on my own subjective listening evaluations.......that a file of this resolution is on complete parity with the original disc.

Now that Hard Drives are going 1TB and higher......its finally possible to make Computer-based playback systems be sonically identical to CDs, with no loss of data.

And, I'll be able to "rip" my CD collection to wave files, without all the technical mumbo-jumbo. No more compression algorithms to worry about. No more "should I VBR or go 320 kb/sec.?" Just DRAG & DROP the CD's tracks into your HD.

Computer DJ'ing will be finally something I can get behind.......as soon as somebody designs a system that is SIMPLE, EZ TO RIP CDS, & SOUNDS GREAT.

oh, yeah-----must be able to do Key Control at +/- 10 bpm.

Hello People

Just a quick hello as a newbie here. Been a VERY long time since I have posted on any DJ board.

Just wanted to add that as a builder of custom rack mount PC gear for DJ's that the bit rate is indeed a wave file.

For MC, a big hello! Now there are lossless format compression files too. Only saves about 40-50% of your drive space but produces a mathmetically bit for bit exact copy of the wave file. Easiest one to use and the most compatible with about all the current DJ programs is the one in windows media player and that is what I am now using myself. I have just recently started conveting all my stuff to this format. I first experimented and verified that when burned back to CDR is is indeeed an exact replica of the original CD./

Just thought I would share this with you all. Now back to building another 2U rack mount for now...

Thanks Les!

Yep this is me buddy! Finally got around to using my 26 years of electronics experience on my own side business building these things for DJ's and KJ's and even for home systems. Only CD player I own now is in my PC :-)

Friends and family have been amazed when they see & hear my home system, mush less the gig rig.

later pal..

More or less -- sound quality wise, it's the same.


Now that Hard Drives are going 1TB and higher......its finally possible to make Computer-based playback systems be sonically identical to CDs, with no loss of data.

I always recommend using MP3 format @ 320 kbps. My reasoning is that there is much better tagging ability, and for backup purposes.

Most blind tests (if not all), fail to find any difference in sound quality on the average DJ sound system. Combine that with the noise floor at an event, and there is no perceptible difference whatsoever.

There is, however, a big difference in backup requirements and time spent on the backups.

If you have 1 TB of WAV files, that means you need 3 one TB drives at the minimum. One for your main playback drive, one for backup immediately accessible, and one off-site, in the event of fire, vehicle accident, etc. These have to be updated on a regular basis.

Then, you also lose the ability to do decent tagging, including album art, lyrics, etc. You can tag a WAV file, but most folks do it by simply appending an old ID3V1 type tag on the end. That can also cause an audible click at the end of the song, if the tag is not aligned on a chunk boundary.


Just DRAG & DROP the CD's tracks into your HD.

As I mentioned earlier, they are sorta the same. It still has to be ripped into the computer, as even though an audio CD is basically PCM samples, it is still a different format, and cannot be played directly with a WAV decoder. If you've noticed, you get quite a bit of latency when playing from an audio CD. That's because essentially, it is ripping and decoding on-the-fly.

I foresee MP3 as still being the defacto playback standard for many years to come (both DJ and general population)...

Just my humble opinion :)

Isn't the technology moving so fast anyway.....theres no telling what is coming next!

But I appreciate you early adopters who will have everything perfected and idiot-proofed by the time my Denons bite the big one (in around 2012, about the time Hillary runs for re-election!)

Thanks Les!

Darn I miss those little white envelopes!

Hey Sue, I remember you too!

On Mp3 files, I agree you can not hear much, if any difference in a DJ system comparing to the CD. However, I do believe that lossless is the way to go for several reasons.

I do not want several backups, one for DJ, one for home, one for archiving my CD's etc. This is why I have gone lossless WMA. Now with one format I can satisfy all. In my home system I can hear the difference in MP3 vice CD but not with lossless WMA vice CD. Then if the CD is ever lost or destroyed I can make an exact bit for bit duplicate. The average bit rate for this format is about 740-900 kps so it does not save the drive space that MP3 does but as MC mentioned drives are getting cheaper all the time. Right now I use 2 750GB drives in my gig rig with another 750 external for back up. I am going to need to go larger soon as I have both DJ and Karaoke librarys on them.
