DVS is Magic?!?!

DVS is Magic?!?!

Can someone give me a total run down on how DVS works cause it looks crazy cool but i have no idea what happens.:confused:

The record plays a ā€œbeep.ā€ The computer listens to the beep and translates that information to understand where the needle is, which direction the record is spinning and how fast. So the computer is listening to an audio signal and interpreting that as information. The information is then used to manipulate the sound file on your computer.

no unicorns and fairies? :disappointed:

I had to look it up: Vinyl emulation - Wikipedia

Something to do with two offset sine waves and voodoo

witch craft!! i knew it!!

so would the beeps be different pitches or what?

if you spin faster then yeah, but this would tell traktor to play faster…

just accept that the beeps are linked and tell traktor what to do :wink:

The timecode disc has like a modem signal on it which is then translated into track position of your digital track via the software so the digital track plays as if it were on the timecode disc.
As the track is on the computer you can do all kinds of tricks with it, other than a straight 1:1 playback.

It’s magic for Mr Acquaviva cos he gets paid for every system sold :slight_smile:
I don’t know how true this page is, it’s quite an interesting read tho http://who-invented-digital-vinyl.co.uk/

Ah cool, you’re from Cairns. Been there, ended up in some pub with girls dancing on the bar, it was awesome.

The DVS tone sounds to the human ear like a constant high pitched beeeeeep noise, but it’s something to do with parallel waves being offset. I don’t fully understand the technicalities, but Traktor does, so it’s fine!

hehehe, someone put dontwank as a tag, wtf?

ah yes. Clean up on tag aisle 1!

there’s a better tag :smiley:

added my own :stuck_out_tongue:

hahahahaa…

3 elements. Speed. Direction. Position.

Speed. You have a sine wave. When you alter the speed at which the record rotates you alter the pitch of the sine wave. The DVS uses the pitch of the sine wave to calculate the speed and thus knows at what rate the track should play.

Direction. There is one sine wave per mono channel of audio. One is slightly offset. By comparing the offset between the two waves you can tell whether the record is moving backwards or forwards.

Position. The record is also covered in tiny little packets of information that are specific to that particular position on the record. This is how the DVS knows the absolute position. I don’t really understand how this works as I couldn’t find much info on it.

That make sense?

yes…

who brought back the ā€œbrad <3 karlosā€ tag?

Thanks man.

sigh… :disappointed:

eh?
