Music & Sound Annotation Expert (posted October 2026)

Musicians, producers, music teachers and location sound professionals listen to 30 to 90 second field recordings and log what they hear on a structured web platform: instruments, tempo, key, timed background events and scene details. They also compare recordings of the same song made in different places, and later grade AI descriptions of clips. Onboarding is paid, but no rate is stated. Remote, 20 to 25 hours a week.

What you would do

• Annotate 30 to 90 second field recordings for instruments, tempo, key, background events and scene details
• Timestamp background sounds such as traffic, sirens and applause
• Compare recordings of one song made in different places and note what changed
• In later phases, mark AI clip descriptions as correct, wrong or invented and explain briefly
• Join a paid calibration session at the start and a short weekly sync

What the listing asks for

• At least 3 years of hands-on music or audio experience
• Analytical listening that separates instruments in noisy, real-world mixes, not only studio recordings
• Ability to identify tempo within a few BPM and the musical key, relative pitch with a reference is fine
• Comfort with repetitive, detailed annotation in a web tool, plus clear written English
• Quality headphones, a quiet workspace, reliable internet and 20 to 25 hours a week

Suits gigging musicians, session players, producers, mixing engineers, ear-training teachers or field recordists who can pick apart a noisy live recording by ear.
