You guys don’t use Logic for unmixing ? It works really well and is rather fast.
Logic 12.2 has the best stem splitter out there.
Yes, Logic stem separation is far superior (quality and speed) … it uses the Neural Engine on M chips.
I wouldn’t mind the waiting if Spectralayers stems come up better, but it’s not the case.
I hope Steinberg rework the algorithms.
It certainly is the developers responsability to make this software work as good on Macs as on PC’s. I am not a happy customer as long as this situation continues.
As in you hope Spectralayers will be able to access the so-called neural engine directly like Logic can?
Wouldn’t that involve Apple removing the direct, purposeful access blockade they have that stops any 3rd party from getting in there?
There’s no such blockade…
Technically, any stem splitter that utilizes Apple’s CoreML framework can leverage the Neural Engine. Here are the primary tools on Mac that do this:
1. Dedicated Desktop Apps
-
Go-Splitter (by SoliderSound): This is one of the most direct competitors to Logic’s internal tool. It uses a custom on-device neural separation engine specifically optimized for Apple Silicon (M1/M2/M3/M4 chips) to offload the heavy lifting from the CPU to the ANE.
-
Stem Split AI: Available on the Mac App Store, this tool is built natively for macOS 13.3+ and specifically leverages the Neural Engine for faster, offline processing.
-
Hush Pro: While primarily known for noise reduction and “de-reverbing,” it is a great example of third-party audio software that explicitly states it uses the Neural Engine and GPU on M-series Macs to handle its machine-learning models.
There seems to be some disagreement that THAT is direct access 
…“Apple’s official documentation confirms that third-party applications do not have direct, low-level hardware access to the Apple Neural Engine (ANE). Instead, they must interface through higher-level frameworks like Core ML,…”
I’m all for learning new opinions, discussions on bottleneck sources etc etc…
however in general, I don’t care one way or another a whole lot what Apple does as I’ll never again use anything they touch or make .
Reading about them though, is always somewhat amusing to me
You can add “Ultimate Vocal Remover” (it’s not just for vocals), to the list of apps (uses the GPU).
I’m no apple fanboy, used to use Logic on a PC.
With Apple silicone, they have become a lot more competitive, a mac mini costs as much as a robust video card.
DosWasBest, what’s your beef with apple ??
So I just tried to use spectra layers voice denoise and mix noisy speech for the first time on a MacBook Pro with an m4 cheap and I was shocked how slow it was compared to my acer laptop of 4 years ago. Of course I will use the other laptop for the job, but I wasn’t expecting that and I agree with whoever mention here there should be some information from Steinberg about this on their site, in the requirements.
