Does Stemverter 3 work on Apple Silicon M1 & M2?

• Yes! Stemverter 3 supports macOS 10.13 High Sierra – 13.1 Ventura, on both Intel and Apple Silicon Macs.

Why do the output files sometimes sound filtered?

• When Stemverter 3 separates the stems of any given song, it uses Artifical Intelligence to determine which frequencies to target and filter, based on “models” that have been trained using a large data set fed into the Machine Learning engine. These models have been trained using music from MANY different genres, so the frequencies are a kind of one-size-fits-all approach, and can lead to variations in which filters are selected for separation depending on the song input.

• The files that sound the best when processed are the songs that the producers and recording engineer have left an appropriate amount of “space” between instruments and sounds in the mix at the time of mastering. Some music producers/engineers have a practice of over-compressing audio to achieve maximum punch, and through this process, they are actually degrading the quality of the audio in the mix by blending the frequencies into each other. When this happens, it is becomes more difficult for the Stemverter 3 to choose the frequencies to separate, according to it’s trained models, which can lead to output files that sound less-than-satisfactory. This is not the fault of the software or process, but a direct result of the choices made by the production engineer who mix and mastered the original recording.

What are the ideal conditions to achieve best results?

• For best results, we recommend using high quality, uncompressed audio sources for file input, to get as close to studio quality as possible. In the most extreme best-case scenario example, one would use a FLAC provided directly from the release platform, provided by the studio that published the original recording. Obviously, that’s often not a realistic scenario, as music that users have in their collections is sourced from a wide variety of outlets. What we’re really saying here is, you’re not going to get high quality results when using low quality audio for input. Try to avoid files that have been remixed, edited, or otherwise altered. For example, if you want to separate a particular track to target the vocals, your best bet is to use the Original release, not a remix or edit, as there is likely to be less quality-loss from conversion and compression as the song has been re-processed by various music producers over time. We recommend purchasing FLACs of original recordings from 7digital for use as input to experience best results.
