Do you think high sample rate give better control of DVS?

You don't need RIAA for V2 / V2B & you should try to use 48 Khz or more if your sound card support it. You will have a much better feeling on DVS use.

Using RIAA at frequency higher than 44.1 khz may crash the program or give unexpected results with 6.27 edition, 6.28 coming next resolves the bug.

I play with a bandwith of 96khz and with a latence of 5ms.
According to me it's a marvelous sensation because the sound feels like better.

My little Delta-44 support perfectly this frequency and until now I didn't have any crash program.

Step by step, we begin to reach the real vinyl sensation! :D

i tried 96khz with my quatafire 610, no crashing

but the bass line is thicker and deeper but softer on 96khz ( i play progessive trance), but very detail

at 48khz, its very detail, but you still have the "hard" feeling of the trance bass

I don't understand how the frequency of the timecode reading, can change the quality of the mp3 ouput... :shock:

I thought the same thing spark....Surely the qualty of the output is limited by the way the mp3 has been encoded and all mine are at 44.1 and 320kbs....Maybe Im being dopey?? I'll try it later anyway and see what happens.

OK....I've tried and it runs without a hitch (so far anyway)

Why does MV recommend this? I cant imagine the sound engine takes an mp3 which is encoded at 44,100khz and converts it on the fly to 96,000khz. In theory this sounds like a fantastic feature but surely not the case. Could someone advise if this is what in fact actually happens? If it is I think I'm going to celebrate.

m3lv :lol:

The use of 96khz for data streaming from the timecode, allow DVS to have much data to determine position and energy, so this give an accurate view of the position in the TC and a more realistic feeling : more data, more precision.

THIS IS DONE TO THE INPUTS !!! between the vynil and the DVS.
But the audio engine remain the same as usual. So you can't have a better sound.

It's like having sport supension on a car and telling your car is more powerful : it's not !!!
You're just faster in curves (better feeling and body control) but your engine is still the same : no more power made.

If you can't see what mean, take pics like an example.
If you have a pictures that is 320*240 on your PC, and resize it to 1024*768, what happen ??? :lol:
Why ?
The dot/pixel added in the pics are interpolated from other points/pixels, that are close to this empty spot, then the spot is filled with this 'average' value.

So this is not resampling/oversampling, it doesn't affect outputs. Don't forget too, that more data mean more power for processing.

Working at a higher sample rate can also reduce soundcard buffer latency, as on a per sample basis it equates to less time in ms.

I'm not sure whether this is in relation to mp3 sample rate that you rip music at, i.e. 320kbps, but I use the U46DJ and i've tried 192-320kbps and the response has been the same. I use the 256 setting in mixvibes and have not had any crash troubles or issues since the RC1 update. I spin pretty often. Eventually I will upgrade my U46 to something better but for now it works perfect.
