This work was done with an Audio CD.

In previous audio separation processes, the source file was in the Video Clip mp4 format (160kbps AAC), which made mixing a bit problematic.

This time, the results were very successful with the INXS - Need you tonight (32bit 48khz) lossless source file. We specifically tested S1 Separate Stems against SpectraLayers 12. The results were better for drums with SL12. The bass and melody channel effects are similar. I'd say it's the highest quality separation process we've ever done. Pay particular attention to drums and vocals.

Studio One audio separation (the new Stem Separation version 1.1.1.106) was used, and this updated version is better. However, the SL12 audio separation, especially the drum quality, is impressive, and the vocals are very clean with v12. The source audio format and quality are important factors.

This audio file was separated using mp3 format and 160kps. We tested it separately with Studio One v7.2 and SpectraLayer v12. When the music file data is insufficient and in low format, separation with both plugins produces similar results.

Drums: Pro-Q4, Pro-C2, CLA Vocals, and SPL Transient were applied.
Vocals: Pro-Q4, Pro-DS were applied. Waves H-Delay and Compressor were sidechained with the FX channel.
Other channels: Pro-Q4 transients and Soothe2 were added.
Extra: A rhythm was added to the darbuka (hand drum)
