Music & Sound Annotation Expert

Musicians, audio engineers and sound recordists listen to short field recordings and log what is audible: instruments, tempo, key, background events and scene details, entered through a structured web platform. They also compare recordings of one song captured in different places, and in later phases mark AI descriptions of clips as correct, wrong or invented. The remote engagement asks for 20 to 25 hours a week.

• Annotate 30 to 90 second field recordings for instruments, tempo, key, background events and scene details
• Compare paired recordings of one song made in different places and note what changed
• Grade AI descriptions of clips as correct, wrong or invented, with a short explanation
• Join a paid onboarding and calibration session and a brief weekly sync
