Topic: i just don't get it.

Dieses Thema ist veraltet und kann veraltete oder falsche Informationen enthalten.

with every new release of virtual dj.. vdj 4, vdj 5, vdj 6 there is a new and more impressive sound output.

it's more clear. it's more sharp. the timecode latency has improved. the scratching has gotten better.

but i can not tell the difference between the sound output of 3.4 and 6.0.1

could someone please tell me what's the difference?

has anyone actually gotten compliments from clients saying that the sound got better? i haven't.. and i've been using virtual dj since 3.2

i seriously don't get it? isn't sound a hardware item?

if you tell me a 24 bit audio sound card can handle more output than a 16 bit audio sound card.. so, the speaker gets more beats to play... so the sound is better. ok.. sure.. i get that.

so, would someone.. anyone... who actually understands the technical part of it, please tell me what exactly makes the sound output in version 6 better than version 5.

i'm not complaining, i'm not nagging. i'm not being sarcastic. i just want to understand. so when my client asks me why they should hire me, and i get the signal to tell them something technical about my sound output, i will have something to say.

thanks in advanced.

If you cannot hear the difference.. then I'm afraid... you just will not get it. The difference is so obvious. Do you use timecodes?...Do you scratch?.... if you do.. then there is quite a noticeable difference in sound quality and response in V6. If you still do not hear a difference then...you will not get it.. no matter the explanation given.

I have a friend.. a prominent DJ who is considered one of the country's best..he is totally Serato....admitted that VDJ was nice but sound...was awful....I have played alongside him quite a few times over time.. basically stepping up each version when we met. The comment was always the same... sound.. scratching.. latency issues. Always a critic

Went into the club on Sunday... had a work out with V6.... demonstrating for a (friend of mine interested in going digital). Guess who walked in....looked over... had a play with VDJ....loved the new version.... "way better he said".. never even asked him. Finally getting it.. he said.

I have not had any drop.. or loss of control in V6 even after playing for 8 hours. in earlier versions i have had to turn off my CD players a couple of times in all my gigs to regain control of the timecode... or clone a deck.... and continue using only one deck.. through out.. + deck 1 i could never get it to respond to timecode completely accurate.

With V6.. yes all this have changed.... my scratches are more chirpy, my cues more responsive.... no delays etc..
If you have not experienced or noticed these differences... perhaps you have not had time to fully test V6?





 

Well said ;)
 
stories are great.. they are usually fun and interesting..

but can i get some technical stuff on this?like..
  1. the old sound core could process 512 kilo bits at 16 bits this one can process 1024 kilo bits at 24 bits.
  2. the old sound core could not handle... this one can.

what you're telling me is that you had a computer with less ram. and now that you got more ram, vdj is taking the credit. running out of memory is not vdj, it's ram. but i really don't want to get into that stuff.

i want to understand just WHAT IS NEW IN THE SOUND DRIVERS?

what was wrong with the old one? what was wrong with the sound from v3.4? and why are there still complaints about the sound not being good enough from other users?

First off, if you wish to even begin to understand any technical data,
I must correct you on the basics of digital audio:

Bit depth is a resolution in 'dynamic range' of each sample, meaning
how many steps you have to correctly represent an amplitude change
over time:



In this graph, analog sinus wave is converted to 4 bit digital signal, that means
2ˆ4 = 16 steps. That is why you see in the gray background a jaggy waveform.
With 16 bits, you have a range of 65,536 steps. Time domain also has a resolution
of its own, which is represented by the sampling rate (frequency), meaning how
many samples in time are captured.

Higher bit resolution does not result in a 'more output', or 'more beats to play',
it results in a higher signal to error ratio which is measured in DBs, giving you
an ability to more accurately capture/reproduce low level signals, thus higher
dynamic range.

So, as you concluded - the sound is better, or more accurate to be precise.


Now, what they have probably done regarding timecode is how fast and accurately
can the software algorithm detect the change of the timecode signal and generate
an appropriate response. It's an art of balancing buffer time (latency) and accuracy,
if you have lower latency, that means the reactions will be much faster, but less
accurate, and the other way around.

I don't think you need technical data to understand or hear what is actually happening
when you listen in detail to scratch sound with timecode.

You are misunderstanding..... I am still using the same amount of RAM...nothing has changed in my setup... however... everything is better and responds better.. upon installation of V6
 
@erxon

that's exactly the kind of info i'm looking for, thanks.

can you tell me what you think they did with the actual sound wave?

like, can you tell any difference? i read there's a huge difference, but i just don't hear it.

and this topic comes up with every major update.

and i'm looking at this forum, playing the music.. what happened? i don't get this at all.
 
Just curious, what format is your music saved as: mp3, wav, flac, etc. If mp3, what setttings?

this is definitely a question for another topic. but since you asked: mp3.
