Best Stem Separation Software in 2023

Best Stem Separation Software in 2023

Stem separation tools allow producers, engineers, DJs, and creators to isolate individual song elements like vocals, drums, bass, and instruments from mixed stereo audio. This enables advanced remixing, sampling, karaoke creation, music learning, and more.

In this comprehensive guide, we’ll review the leading stem separator options based on audio source separation quality, features, pricing, and ease of use.

What Are Song Stems?

Song stems are the individual tracks that make up a recording. A stem could be the isolated vocal, guitar riff, synth line, drum loop, or any component of the full song.

On a typical studio project, stems are exported individually from the recording session to provide maximum mixing flexibility.

But using AI-powered solutions, stems can now be extracted from already-mixed two-channel masters and songs to enable new creative possibilities without needing the original session files.

Next let’s explore the top software tools for high-quality stem separation and extraction.
