Listening on Nuraphones, I don’t hear a difference. Soundcloud would surely compress the file format, though no? In that case, you may as well convert one or the other to the other’s sample rate and invert the phase on one, to see if they null. Theoretically, all you’d possibly hear would be any kind of dither noise.

Thank you very much for listening Sam. What I personally hear is some better stereo separation and it's actually not just subtle and I can the difference in clarity hear i evident for instant, in second 2 when the pad Kicks in. If I'm not paying attention they're very close. I will follow your suggestion, to see if they null, but I will also ask my trusted friend (my wife) if she can hear any difference. She has amazing hearing. Just to clarify, those two files are the same incidental format, the difference was in the sample rate of the multi track project for each which makes the test relevant fo the purpose of the issue at hand..

This place is just not the same without Nicky. Glad you're back!!

Very clever and insightful. Thanks!

Don’t rule out confirmation bias. The brain does strange things when it expects a difference. Just sayin’...

You could be right for sure, I don't think that I have any exceptional hearing and I can be just imagining things due to the confirmation Bias. However this is a a small part of a project that I'm currently working on. It includes my custom patches from ABSYNTH and trilogy for bass. Ignore the drums and the fact there's no mastering or final mixing involved in either of the files (and this is still in the sketching stage). There identical except that I changed the project sample rate from 44 to 48 and removed the guitar parts. Can you hear any difference? Is one more clearer and more detailed than the other?

. I might be splitting hairs but I like the 48KHZ better. I'm not disclosing which one it is so that there would be no confirmation bias but I would really like to get to the bottom of this and if no one can hear a difference or have a preference, I will seriously go get my hearing checked (maybe it's about time ). So I'm listening through Studio Monitors in the proper location of the triangle so maybe there would be no detectable difference in less accurate mediums, I'm not sure yet. Please chime in

Thanks everyone that you like our feature update!
Now that we talk digital audio rates again, it‘s time for resolving some digital myths.

If you have any device or software that sounds better at 48 than at 44.1, then it is very bad made.
Especially if a reverb would improve its sound at 48 kHz, it would be a hell of bad code. Can you name one?

There's so many myths about sampling rates that I was unaware of that I did learn while using the Kemper that when I compared the SPDIF at 44K with the analog outs (in 48K Project ) into my audio card that the difference I was hearing was due to the converters of my audio interface. Now Spdif at 44 and 48 and all other rates from the Kemper sound the same which is great and it makes sense.

However there was some projects that included software synths from Native Instruments (Absynth) and in the same project there was Trilogy by Spectrasonic. in Cubase. where as soon as I change the project sample rate from 48k to 44.1K the wow effect, the detail and some clarity in the reverbs for the overall project sounded less detailed. I also had external synths from Roland. again into cubase they sound better and more detailed at 48k using the same audio interface and same mixer. I know these Roland synths specs were 48khz so could it be that the software is optimized to sound best at the sample rate?

I read somewhere that higher sample rates even though the added frequencies they included can't be heard by human ears, their presence in the signal with other frequencies can result in added harmonics that can be heard by human ears.and those harmonics won't be in the signal unless the higher sample rate is used.

By the way, please give me the name of this speed of light converters that can do a an AD/DA in 600 milliseconds, it's usually more than 1 millisecond and it seems to be nothing, but if you add that to the latency you already may have from the rest (Latency compensation from the DAW, digitally controlled monitor, etc:) it's can build up to something anyone can feel while playing.

I think what CK said was the the converters latency is less than 600 Nano Second which means basically no latency. One nano second is one thousand-millionth of a second or one billionth of a second, but you never know some folks can very well claim than they can sense one nano second latency

How are you auditioning the IRs? Through an Impulse player in a computer? When I did that a while back I used a VST plugin player and disabled the cab in Kemper and selected IRs I liked then converted them. When I played them on the Kemper I got same results using the same audio interface that i played the IRs on.

don't forget the Rig packs if you're using Rig manager.

Quote from DannyEvil

Not to dig up a dead horse, but I am attempting to convert some of my IR's and am still experiencing the same thing. I was hoping it would magically fix itself.

Kemper default is to have Pure Cab checked with the level at 3. To get the IR to sound the same in the Kemper, you need to uncheck pure cab (the global setting) and not only lower it to zero.

Get cracking , or cranking.

The other day I was thinking of my dream setup and it included not a single cable or wire, aah one can only dream.

Edit: they used to sell a sticker that reads "creative minds are seldom tidy"

I heard that using the same power strip for the the offending devices could eliminate the problem as ground loops can result from using different wall sockets.

On the Kemper back panel the different outputs have Ground. Lift, red buttons, I believe there's four buttons, one for each set of outputs, have you tried to see if that fixes the issue? If not, it can also possibly be a USB ground loop noise if your kemper is connected to a computer.

Like, on the actual amp or is there a reference volume in the kemper that can be turned up after profiling?

I'm feeding the Kemper the signal coming from an external mixer, so it would on the volume on the mixer and not in the Kemper.

last night I used the Transpose and wow, I couldn't detect any latency. It seemed different than when I tried it a couple of years ago, not sure if latency was updated in this most recent update or before, but this is very playable.

How big of a difference between the 44.1 and 48k for the guitar tone might be something that most will adjust to very quickly, but many of the Synths and specifically software synths will sound much better at 48k. I'm sure many will argue that if programmed properly synths will sound the same at 48 and 44.1. but practically even reverbs sound better at 48K.

So this is a great update to be able to use SPDIF at more than 44.1.

Quote from Awesome_Elvis

Which Volume?

The reference amp volume.

Quote from skoczy

I just got IFTTT notification!

added: S/PDIF Clock can be selected: 44.1/48/88.2/96 kHz
Many, many, many users will be more than happy.

added: Transpose in the Rig Settings
That's great!

I'm one of those, I use 48k and now I can use the SPDIF.

Quote from Awesome_Elvis

I wonder, has anyone tried moving the mic after profiling but before refining?

I tried raising the volume a little and you end up with a louder profile. I bet you that's how some of the unusually loud profiles are accomplished., I however think it messes up the profile.

Try the EQ in the stack section and see if you bump the mids just a little can get them closer. Also you can place the EQ in the PRe position to retain more amp character.
Is the difference subtle or is it staggering?

I don't have the powered version but I know the "Monitor output" is connected internally to the internal power amp and it also has it's dedicated Equalizer from the output section.

Aside from EQ the default volume for Monitor out is -12db i believe so you might try either increasing or decreasing to see if that would make a difference also.

Quote from mars8000

The reason I couldn't do this during profiling, using the reference/amp sounded 100% identical but the results look different after you plug each one of them to the cabinet.

In this situation, you're connecting the Kemper to the guitar cabinet so I'm presuming that you're disabling the Kemper cab and if not then that might be the problem. Sorry if this might sound basic but that's all I can think of.
