Tagged: crackling noise
- 18th December 2017 at 00:52 #29237
I am currently using a x32 Rack + uTrack card to do live recording, but I get hearable static crackling noise. Sounds like an old venyl disk. When I start all up from scratch I get this even on my Microphone channel, which dissappears after a while on the Mic channel, but stays on the Guitar channel.
No matter what guitar I use, if I record it with Kemper in between, guitar directly, XLR, Aux – I alway have this Issue.
Even if I use the uTrack Card with Cubase and Monitor the Input channels, I get this Noise.
I only get this noise recorded on the channels I record, but if I mute the single channels and listen to just the summarized Stereo Output channels, I don´t hear that noise.
I am running out of Ideas now !
Any Tips are welcome.

Do you have a chance to try with the standard X-UF, or X-USB card? Are those working correctly?
The card and the console handles 8 channels groups setting up the routing. Is that noise related on some groups, or happens randomly everywhere?
How about if you have that noise on one channel then you swap the groups in the routing screen?
What is the firmware version on your card?26th December 2017 at 04:20 #29244James GardnerParticipant
I also have the same issue.
2 X32 Racks, both with uTrack cards in them running the latest firmware.
Both record crackling across all channels (running 16Ch in each).
Also over USB or ethernet the uTrack software will not recognise either card. I can browse to them to do a firmware upgrade without issue but the actual application can not see them..
Given both systems are doing the exact same thing, I am presuming it is a software/firmware issue.
The crackling is a major issue as it makes the box unusable.
Should I roll down to an older firmware ? has this been tested with an X32 Rack ?2nd February 2018 at 18:03 #29416
same problem here!
did someone solve this problem to date?

Please tell me the firmware version on your device, and also the exact setup/routing.
Also tell me the USB drive brand and type please.2nd February 2018 at 19:48 #29419
I just found out, that it disappeared with 44,1khz settings instead of 48khz
here was may post (in german) in a X32 Froum… I will translate it. as soon as possible
Hallo liebes Forum.
Ich habe ein paar Fragen, Probleme, etc…
vielleicht kann der/die Eine oder Andere ja helfen.
Ich habe mir gerade ein zweites X32 Rack als 2x Synth-Mixer gekauft (ja, wir haben ´ne Menge Synths auf der Bühne)
– diese Information nur Richtung Benutzerfehler (ich benutze das andere jetzt seit 2 Jahren, und kenne mich, glaube ich, recht gut damit aus.
– sinnlose Ergänzung für die Thomann Diskussion, ich habe dort jetzt den letzten X32 Rack gekauft – hatte die Firmware 2.5..scheint also dort seit einer gewissen Zeit zu liegen … habe jetzt aber ein Update “drauf-gespielt”
beim neuen X32 – wieder inkl. UTrack 32
habe ich übles “Crackle”s auf der Aufnahme.
die nur verschwinden, wenn ich die Aufnahme auf 44,1khz stelle.
– Habe es mit beiden UTrack Karten probiert.
– im ersten X32 funktioniert allerdings 44,1 / und 48khz .- wie gehabt.
wird im SETUP unter CARD
im alten nicht – der Bereich ist ausschließlich grau
im neuen Menü unter
HOME – INPUTS
steht “Card 1-8”
im alten Menü
die Firmeware ist jeweils gleich
3.07 (ich weiß es gibt 3.08 – aber es läuft mit 3.07 auf dem alten, und darum möchte ich dies nicht kurzfristig ändern)
und die UTrack Karte ist in der 3865 Version
– was mache ich falsch?
– kann mir jemand helfen?
– ist es einfach verrückt?
– soll ich es einfach auf 44,1khz lassen und warten – was von alleine kommt – geht auch von alleine wieder – alte Grippe Weisheit, allerdings nicht bei Aufnahmefehlern überprüft.
Danke im voraus und liebe Grüße

Update: A friend of mine bought a Behringer x32-Rack-Mixer + the Cymaticaudio – uTrack x32 Card and immediately got the same Problem – “Crackling Noise” after a couple of min. So we took the Card and plugged it into my x32 Producer – Mixer, recorded for 3 hours and found everything OK. My friend played around a bit and switched from 48kHz to 44.1kHz and the crackling Noise was gone.
Fazit: Currently the Issue only shows up on a Behringer x32-RACK Mixer with uTrack x32 Card running on 48kHz.2nd February 2018 at 23:17 #29421
Thank you very much,
Yes, it works with 44,1khz
Strange thing, that is works with 48kHz at my other X32 Rack, same firmware version7th February 2018 at 18:11 #29436

Guys please provide me the following details:
1. Firmware version on the uTrackx-32 and the firmware version on the Behringer console
2. Do you have that problem on 48kHz only and never happens on 44.1?
3. Do you able to use with the same setup the standard X-UF or X-USB card on both two sample rate with no problems?20th March 2018 at 03:43 #29574
Same problem here, it ruined an entire important rehearsal recording and weeks worth of setup and planning :-/
Anyway, here’s my setup:
1. uTrack-X32 firmware 3865, x32-Rack firmware 3.08
2. Mostly happens on 48 kHz either immediately or after a couple of minutes. It’s mostly audible when the channel signal reaches a certain threshold (above -30dbFS or so). After it starts, it seems to be persistent, even after a console power cycle. Switching the console to 44.1 kHz immediately solves it. Switching back to 48kHz immediately brings back the crackling.
3. Cannot test the stock card right now, sorry, but I might have the time later this week.
The effect is the same when recording to USB drive or when using the card as USB interface with a MacBook.
I captured and uploaded an example of how it sounds, maybe it helps: https://drive.google.com/open?id=1JFsKEn_8g_RwVJXFkpRMstR42yI8VTvE
Let me know if there’s anything else I can help you with in order to fix this issue.20th March 2018 at 19:14 #29576
If you change the routing on the console the noise present on the same channel (number) or goes to the another channel where you changed the routing (instrument)?20th March 2018 at 19:37 #29577
I just installed the X-USB and can confirm that it works on 48 kHz (and 44.1 kHz) just fine (been running for about 2h straight now).
The noise on the uTrack was present on all 16 local channels. As you can hear near the end of my sample recording, the noise isn’t constant but “follows” the actual signal’s amplitude. I’m not sure whether or not it was present on the channels coming from my SD-8 on AES50-A. Gonna check this next now.20th March 2018 at 21:34 #29578
Ok, the behaviour seems a bit tricky to reproduce, so here’s my “what I did” log:
– After building the uTrack-x32 back into the x32-Rack again, I immediately connected it to the computer via USB.
– Turned on the console, it started in 48 kHz and the uTrack sends audio to the computer *without* crackling. It’s doing this for the last hour straight without an issue.
So only using it as USB interface seems to work fine. The bug has to be triggered, here’s how:
– With the console still on 48 kHz and the computer still connected, I connected an external USB hard drive (WD Elements). Waited for the light to turn green, and pressed the physical record button on the uTrack-x32. I let it record to the hard drive for about 2 minutes, then stopped the recording by holding the record button a couple of seconds.
– I disconnected the USB hard drive. The computer, which was still connected that whole time, got audio again — but this time *with* the crackling.
A couple more observations:
– Turning the console off and on after this does *not* get rid of the crackling.
– Switching to 44.1 kHz gets rid of the issue.
– Switching back to 48 kHz (even after a couple of minutes operating at 44.1kHz) immediately brings back the crackling.
– Disconnecting the whole console from power, waiting a couple of minutes and turning everything back on again *does* get rid of the crackling.
I hope that helps. Again: if there’s something else I can help with, just let me know.22nd March 2018 at 11:49 #29582ChetanParticipant
Thanks a lot for the detailed description of the problem. Interestingly enough we were never able to catch this problem until now.
Laszlo is on vacation, but when he is back, the first thing he would try is to see if he can reproduce this problem with your description.25th March 2018 at 12:56 #29594
So I sent my x32-Rack Mixer with the u-Track-x32 plugged into x32-Rack-Mixer for repair to Behringer.
Got it back after 8 weeks, but nothing changed.
If I plug in my Kemper Amp (nothing else) with 48kHz, record on the USB stick by pushing the button on the u-track,
stop recording by pushing the button on the u-Track and listen to the recording I immediately get the crackling noise.
Switching to 44.1 kHz during recording never shows any Issues. This is 100% reproduceable all times.
Plugging out this u-Track-X32-Card from my x32-Rack-Mixer and plugging it into my x32-Producer never created any Issues no matter what settings I used.
– If you just use a Microphone it takes around an hour until the crackling noise Shows up
– If you test this with an acoustic guitar (checked out 3 different models) it´s reproduceable after a couple of min.
– It´s completely Independent on any other factors (which channel I use, guitar model, loud, quiet, other settings – no matter what)
So in my eyes this Issue has always been there if you combine u-Track x32 with an x32-Rack Mixer.
I assume it just didn´t show up so far, as many Sound engineers use the x32-Rack as a Stagebox.
I really appreciate, that Lazlo will start to try reproducing this issue in order to find the Problem.
Aside that the u-Track x32 recording card is really relieable with 44.1 kHz on x32-Rack and with no Limits in x32-Producer and I still like it !
If you need any more details on how to reproduce this, I am glad to answer questions as well.

I don’t know if this is related, but my recordings have a terrible noise to them on all tracks.
Last Sunday I recorded about 3 hours with no troubles.
Friday night I recorded a good 5 hours with no troubles whatsoever.
Saturday and Sunday I recorded about 10 hours each. All 32 tracks of every recording sound like this:
The only thing I can think of is that I’d loaded last Sunday’s snapshot on Saturday. Everything else is the same – same power, same hard drive, same control network. The equipment was packed up and moved each night, so the equipment was hard booted each morning.
The card, the X32 Rack, and the SD16 are all at the latest firmware, and I was triggering recordings via the app. The live sound was pristine, and the board was running at 48KHz.
Now that I’m home with the equipment, I’m unable to reproduce the problem at either 48 or 44.1, and the tracks recorded are perfectly clean.
Is this a facet of the same issue, or something different?3rd April 2018 at 14:50 #29621
@akoreneff that seems like a distinct problem, at least soundwise: it doesn’t sound like the issue we are discussing. This one sounds more like this: https://drive.google.com/open?id=1JFsKEn_8g_RwVJXFkpRMstR42yI8VTvE23rd May 2018 at 16:31 #34653Ian DyerParticipant
I too have had huge problem with recording via X32Rack at 48Khz. 32 tracks that all sounded like line level sources recordedinto mic inputs i.e. sounding horribly overmodded.
Trying to reproduce the problem resulted in some recordings OK, some with clicks, some with crackling. But as with everyone else here, 44.1kHz recording is fine. Also no problems at all in two years of using uTrack X32 in full X32 desk at 48kHz.
I reckon these are all slightly different manifestations of the same (clocking?) problem when using the card in X32 Rack at 48kHz.
Would anyone from Cymatic like to update us please….?28th June 2018 at 15:10 #37424MilanParticipant
Hello, I have the same problem on M32. 48kHz cracks, 44.1 kHz is OK. I’ve downgraded the firmware to 3.07 and everything works well.2nd July 2018 at 17:52 #38071MilanParticipant
So if I record for a long time, crackling will appear again. Downgrade did not help much.19th October 2018 at 08:02 #42403Terrence HealyParticipant
If you read the manual the answers are there, 44.1Mhz on everything.
Use 7200 RPM and up spinning Disks. Raid 5 Enclosure with 3 drives can give you 1500 RPM connected to a laptop.
USB Hard Drives
A USB hard drive stores data on spinning magnetic disks. This is the recommended type of USB media to use with the uTrack-X32, because it has reliable and constant read/write speeds.
USB Flash Memory Devices
A USB Flash Memory Device uses flash memory. Small, cheap flash devices are generally not adequate for use with the uTrack-X32, since they require occasional pauses in data writing. This is problematic for a device that needs to write a constant data stream: a pause in data writing may cause dropouts in your recording.
Some flash devices will perform correctly. Generally, it is easier to find a usable flash device within the ones marketed as SSDs (Solid-state Drives).22nd October 2018 at 15:02 #42504
New firmware release available for download, the new firmware should fix clicking issue when using the card with some new revisions of mixing consoles.30th November 2018 at 08:56 #43439Dirk SchulzParticipant
I still have this problem, but only when recording AUX IN 1-6/T on my X32 Rack Console. Firmware on both devices is the latest version (3.09 / 5000). I loaded the recorded file into my WAV editor and had a look at the signal. Partially the signals have been cut on the bottom all on the same level. I only recognize this when recording AUX IN 1-6/T! Are there any workarounds?
Dirk3rd December 2018 at 13:56 #43476
I can confirm that there is an issue if the recording source set AUX IN 1-6/T.
We are started to investigate that issue.
If there’s any workaround or solution for this problem we will publish that on the website.
Thank you for your input.27th December 2018 at 11:11 #43872
I am the happy owner of a new X32 ( the big one ; 32 XRL In / 16 XLR out ) bought on Thomann this month ( dec 2018 ) with the Cymatik u-Track-X32 card.
I Experienced the same issues discussed here on this thread.
I Just recorded a live concert of 80 minutes with 16 track, and every tracks have this bad crack.
I recorded on 48Khz, with a 120Go Transcend SSD witch work perfectly ( no smart error, and freshly formated with the UTrack button. Read/Write up to 120Mo/sec on usb3 on my Asus ROG Laptop )
The record use many different microphones with or without 48V phantom alim.
You can ear a sample here :
And see the waveform of the full records on protools 12 here :
I experienced the same issue with a direct USB record on protools, with the last driver downloaded last week on your web site. With 48Khz.
I have to reboot the X322 one or two time to get a record without crack. But I’m not reassured, the recording doesn’t seem very clean, even if it doesn’t crack.
The Firmware of the X32 is 3.08.
Don’t know how to see the UTrack firmware.
Did you know how to resolve this issue ?
If you need some additionals informations, tell me !27th December 2018 at 11:16 #4387327th December 2018 at 13:11 #43875
We have correct this issue with the current firmware release.
Please take a look here how to update the device: https://cymaticaudio.com/images/downloads/manuals_and_brochures/Cymatic_uTrack-X32_FirmwareUpdateGuide.pdf7th January 2019 at 12:44 #44060Christian KnocheParticipant
thanks for solving this problem!
Unfortunately there is no newer firmware than 5000 from 8th october in the downloadsection of utrack X32 available 🙁
Christian8th January 2019 at 07:37 #44095
After the firmware update, everything seems fine.
No more crack on the USB SSD disk. The clock seem good.
Thanks for all !10th January 2019 at 10:19 #44158Dirk SchulzParticipant
Hey guys, please upload the new firmware. There is still offered the October (5000) version in your download section. Even the release notes do not contain the fix of noise on AUX IN recordings. Thanks in advance, Dirk
