From developer SoliderSound comes Go-Splitter, a free stem separation app for macOS and Windows.
We’ve had a few stem separation tools come along over the last handful of years, especially since terms like neural networks have become a regular feature of conversations about audio software.
Since LALAL.AI in 2021, we’ve had more recent additions, like Eldoraudio’s Stem Splitter (Eldoraudio also released a handy piano-to-MIDI converter).
Many services of this type are web-based, which can be problematic for some users for several reasons.
First of all, it requires a stable internet connection, and not everyone likes to work online.
Secondly, some users have privacy concerns about dropping tracks into any cloud-based service.
It seems the appeal of Go-Splitter is that it’s a neural-network-based stem separation tool that runs locally on your machine.
Go-Splitter is available as a standalone app for macOS (12.3 or later) and Windows (10/11).
The app splits your track into four stems: Vocals, Drums, Bass, and Other.
By comparison, that’s two stems less than Eldoraudio’s Stem Splitter, which offers piano, vocals, drums, bass, guitar, and other. But, of course, that’s a web-based service.
In this case, various instrumental elements can be bundled into the Other category.
The only thing that matters is the quality, and like most alternatives, it’s mixed. Depending on the source file, you can end up with some fairly clean stems and some not so clean.
I would suggest that the embedded demos on the product page perhaps don’t do the app justice; most of the vocals are heavily processed, and it’s not clear whether the separation is particularly good or bad.
Having said that, you can pull some usable, clean(ish) vocals, so it’s worth trying. Drum and Bass stems are typically usable but can be a little tinny at times.
If you want a step up in separation quality, there is a pro version, currently available for $45 (usually $78).
The Pro version also offers additional features, such as key detection and advanced tempo change functions.
I’d have liked to see the free option offer the same level of separation quality, and perhaps more stems from the pro version.
The workflow is similar to most others, making it straightforward and familiar.
Drag and drop your audio file (WAV, MP3, FLAC, M4A/AAC, AIFF, OGG), and let Go-Splitter analyse the song, which doesn’t take long.
Once the stems are separated, you can preview and export.
Have a go, and let us know what you think.
