Background noise problems

I’m having numerous background noise problems in Cubase 13.
I use (obviously) Cubase and a Neural DSP Plugin.

If I use the stand alone version of the Neural plugin I NEVER have problems and I hear perfectly without hearing noises, so everything works perfectly.

The problem therefore only occurs with Cubase and not always. Sometimes I play for 30/40 minutes without problems and then at a certain point it starts to give problems. At that point I have to close everything and reopen hoping that it will resolve itself.

I tried to reinstall the software from “steinberg download”, but I don’t know what else to do!

I’ll give you some info:

Audio Interface:
Steinberg UR22C
Input 2 with Hi-Z active with guitar connected directly
Gain 0
Headphone output connected volume 3/4 with wired Marshall headphones

Dell Inspiron i7-11 64GB RAM; 2GB Video; 1TB SSD; Windows 11
Connected via USB-C to a with 3 monitor. The audio interface USB is connceted to this.

Guitars tested:

  • Gibson Les Paul
  • Fender Stratocaster
  • Duesenberg Starplayer

I leave you a WeTrasnsfer link with two examples to help you understand:

  1. small test with slight noise
  2. recording test with 3 tracks, the first two work “well” even if not perfectly. the third one that enters at about second 35 makes a noise

Thanks everyone in advance!


Could you try to increase the Buffer Size, please?

here my settings now:

The result is the same. Sometimes when recorded you hear that noise and when I listen back the audio skips and it almost seems like I didn’t record anything.
I played about thirty minutes with these settings and no problems until it started like this: WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free


In this case, use the LatencyMon utility to inspect your system, please.


Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:09:52 (h:mm:ss) on all processors.

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Average measured interrupt to process latency (µs): 14,368602

DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Wich Buffer Size and Sample Rate do you recommend?
