Hello,
I’ve just installed the new Spectralayers 12 and Unmix Song is giving me some weird resonance/noise, the higher the quality setting the more resonant. If I use ARA it may show up inside Cubase but when I have to bounce the track the resonance shows up again.
Thank you! and congrats on the new release!
A sharp band pass filter got me to find it in the whole unmixed track at around 5,4kHz.
Hope you find a solution for it.
Thank you.
Hello, has anyone encountered something like this? I´ve found no workarounds. Thank you.
Hello!
I downgraded to Spectralayers 11 to check and it doesn’t have this off resonance. Would it be possible to contact developers for a bug report?
Thanks!
Is it happening in every project?
Can you share the file you’re trying to unmix?
You have noticed the new release:
Hello! @Jonas2021 I’ll try the new release out and if the noise still happens I’ll share part of the audio like @Tanant sugested. Thank you.
Can you please tell us your system setup and what settings you have used exactly? High, medium, CPU/GPU rendering, etc.
this infos are helpful.
Sure, I just installed the new build and it the noise is still there but I noticed that if I mute some channels the noise dissapears. I’ll get a screencap of it and share. I’m thinking it’s a phasing artefact rendered at some point.
Spectralayer 12.0.10 Build 423
12th Gen Intel(R) Core™ i9-12900 (2.40 GHz)
GPU: D3D11 / NVIDIA GeForce RTX 3090 Ti Driver version 576.80
Unmix Song, Quality High
I guess it is being rendered in my GPU, I cannot find that setting in the setting, where did they move it to?
I’ll be back later during the day with more info, thank you.
Edit >Preferences>SYSTEM
Did you check the DeBleed function?
It says:
Auto. Using NVIDIA GeForce RTX 3090 Ti.
I’ve yet to use the DeBleed function. I’ll also try it out later. Thank you.
Hello. I cannot share the whole project but the end of the project seems good enough. I also had to convert it to mp3 but the noise still shows up there too, I checked.
You open it on Spectralayer 12 and run Unmix Song, Solo the guitar and the noise should be there. Also, if you turn the Solo on and off again the noise pops in and out which I’m sure is not expected behaviour.
Thank you.
Edit, it turns out you can record audio from system coming out from Spectralayer, I wish Cubase had this!
I don’t know if c14 has SL one included…
If your soundcard has loopback, you can record system sound in Cubase. I know Esi Uno and RME´s does that
@Jari_junttila this is how I monitor cubase most of the time, useng loopback, using blutooth headphones. It is very convenient for the craetive process not to get si the studio monitors.
For many years and tears I have request that Steinberg fix this and have a propper windows Lwo Lattency Driver like in Spectralayers has now but the issue has been ignored for years.
fix it…FIX IT!!
It seems a matter of the client (Wavelab, Spectral Layers, Cubase, what not…) to support loopback-recording.
See here
Isn’t it amazing?
Hi irregular. I downloaded the sample and noticed some strange behavior, but I think this is due to unmixing a ‘song’ when there is only a guitar…? Not sure. It seems like the ‘Other’ track and the Guitar track have phasing issues that cancel each other out when played normally i.e. the original sample assuming null summing, but when one of them is muted or soloed, the artifacts are noticeable.
I do agree it’s weird behavior, but I also don’t know why you would want to unmix a song when it’s only a guitar - I’m guessing this is where the parts you can’t share come in 
Maybe try to clean up that part of the audio (acoustic guitar noise) before unmixing? My guess is it’s trying to separate something that doesn’t need separating but doesn’t know what to do (the AI model), because ideally that part of the audio would be 100% guitar, no unmixing needed.
EDIT: Sorry, should add: They appear to be two separate issues; your initial audio clip and the one I am replying to which has the click/hiss at the end. I cannot replicate the first, but I can definitely hear distortion of some sort in the original audio.
Hello Tanant. The original recording is from an XY mic setup for an acoustic guitar. It has a lot of bleed in from other instruments, including voice, and I expected Unmix Song to do well enough to save the recording. I’m going to have to do something else if I can’t save it with this method.
The issue here is Spectralayers has been a very good adition to my tools but if it generates distorsion or weird noise at some point I will not be able to use it very frequently.
Thank you for your comments. I’ll see what I can do about this.
Edit:
I teste the three quality settings (Fast, Balanced and High) and the resulting noise artefact is similar in amplitud.
