audiophilous
Maybe my question has already been covered on the forum, but a quick search didn't come up with anything useable.
I received a free version of the Virtual DJ software with my controller, and I'm evaluating the different DJ software packages on the market before purchasing.
When mixing in the old-fashioned way using vinyl and a DJ-mixer the following happens in the audio chain:
- vinyl is pressed at the plant using the RIAA pre-emphasis curve (see http://en.wikipedia.org/wiki/RIAA_equalization for more information).
- when playing back, the phono-preamp in the DJ-mixer applies an inverted curve, resulting in a more-or-less 'flat' frequency response
- when using the pitch-control on the turntable, the pre-emphasis curve consequently moves upwards or downwards in the frequency spectrum
- however, the RIAA correction curve in the pre-amp stays at the same spectrum
- the result is hard to describe in words as it is a function of the pre-emphasis en de-emphasis curves working together. Generally speaking, it sounds like an automated equalizer which is fully dependent of the position of the pitch control on the turntable (playback speed).
Take a look at the image on http://www.beigebag.com/images/riaa/riaa_1_1.jpg to visualize the effect. When using the pitch control the 'record' curve moves up or down, and the resulting playback frequency response will show addition bumps or cuts.
In my opinion, this effect greatly attributes to the well-known 'vinyl sound'. I really really like the sound of this effect, as it adds to the analogue feel of a record.
My question: has something like this been implemented in the Virtual DJ software (somewhere behind the scenes)?
If not, I will file a request for such a function

It's not in the software native. But... look in the ad-on's section of this site. There is a plugin someone wrote to simulate the RIAA curve.
If that isn't close enough there is information on the VDJ site about writing your own plugin.
Example:
What your really trying to do shift the pitch up you move all frequencies up the curve when speeding up the tempo. Digital quantiziation screws things up. But an adaptive EQ plugin could simulate riding up or down the curve dependent on the tempo slider position.
Have fun!
