BandLab Splitter
BandLab Splitter is completely free. The trade-off is that it's music-focused only and doesn't offer speaker diarization features.
Final Verdict
These tools aren't really competitors - they solve completely different problems.
BandLab Splitter is an excellent free tool for musicians. If you need to isolate instruments from songs, create karaoke tracks, or extract stems for remixing, it's hard to beat free.
SplitBySpeakers is the right choice if you work with spoken content - podcasts, interviews, meetings, or any recording where you need to identify and separate different speakers. This speaker diarization capability simply doesn't exist in BandLab Splitter.
