Sample rate 44100, 48000 or 96000 when using 320kbps?

[DJ Shifty Sheep]

I'm using Traktor S4 PRO as my software & all the MP3's I purchase are 320Kbps.

So what would be the best sample rate to use 44100, 48000 or 96000 when using 320kbps?

I understand if using WAV's then 96000 would be the best option and keep the highest quality, but with 320kbps mp3 do's would it be best to drop it to 48000?

At the moment i have it set to 96000, was wonder what other people have theirs set to & what bit rate the files they use are?

44100 is all you need

[DJ Shifty Sheep]

The reason I use it the way I do is on 96000 with a buffer of about 320 I get a latency of about 7.1ms.

Mp3 have a sample rate of 44100. The only thing you earn with increasing it in Traktor is CPU usage.

What have most you guys got your

A, Sample rate

B, Buffer size in mb
set to?

& whats the latency/processing time in ms with the setting you using?

[DJ Shifty Sheep]

They can also be 48000 so I guess that will be my new setting as I don't play WAV's.

But why can i achieve a lower Latency/process time with a higher sample rate?

[padi_04]

Sample Rate: 44100
Buffer: 128

Procesing: 2,9ms
Output: 2,3ms
Overall: 5.2ms

I've just done a little experiment there and I'm not happy with NI!

If I use the S4's sound card I get a lot higher latency than what I do with the same settings on my Pre sonus audiobox usb (external usb soundcard)!!!!

For e.g.

Audio Device - Traktor Kontrol S4 (core audio)
Sample Rate - 48000
Latnecy 128 - processing 2.7 output 5.7 overall 8.4

Audio Device - AudioBox USB (core audio)
Sample Rate - 48000
Latnecy 128 - processing 2.7 output 1.5 overall 4.2

Thats a massive difference!

I have one theory that it could be to done with when using a external USB sound card all sound is handled by one USB cable and the NHL/midi by the other!
Either that of the sound card in the S4 (or drivers) are less than desirable.

The down side to using the S4 as a controller and dedicating a usb sound card is that the master volume is controller by the soundcard not the S4 and the headphones don't work =(

I want my S4 sound card to have the results the USB sound card gets. If it is to do with amount of able I wouldn't have minded the putting 2 on the S4 and saying the reason we have add the 2nd one with to handle the sound to make it shit hot!

any thoughts?

Anythoughts

[theory28]

did you try going lower? or is that just the default latency?

[DJ Shifty Sheep]

I could go lower at the risk of audio drop outs!

My main point is that my S4 sound card is 4.2ms SLOWER than running a external one on exactly the same settings!
