Music Professional - Stem Source Separation Expert

What You'll Do5

• Listen to short audio segments and note each instrument present.
• Sort sounds into specific instruments and broader instrument families.
• Label stems that extend beyond the standard 4 to 6 stem groups.
• Apply annotation rules so labels stay consistent from clip to clip.
• Identify overlapping instruments and mark each one in the segment.

Requirements5

• Proof of experience in music, audio production, or source separation work.
• Familiarity with models such as HTDemucs, Open-Unmix, MDX-Net, or RS-RoFormer.
• Ability to identify instruments and instrument families by ear.
• Background in music annotation, transcription, remixing, or music information retrieval.
• Comfort with labeling short audio clips and following detailed annotation guides.

Who Should Apply

Candidates who have worked with source separation models and can prove it through a portfolio or past projects are the right fit. A strong ear for instrument identification matters, along with a music background that covers many genres and ensembles. The role does not suit people who lack direct experience with audio annotation or who cannot share evidence of source separation work. Reviewers often reject applicants who list general music skills but fail to name specific models or annotation tools. A clear, verifiable record of stem separation or instrument labeling gives you the best chance.
