Employer description and requirements
Role Title: Music & Sound Annotation Expert
Role Type: Contractor
Location: Remote
micro1 is engaging Music & Sound Annotation Experts to contribute to a customer's project at the forefront of music and audio technology.
Your ears are the ground truth. You'll listen to short field recordings and document exactly what's audible — instruments, tempo, key, background sounds, crowd reactions — through a structured web platform built for this project. Later phases involve grading AI model answers against what you actually heard.
What you'll do
Listen to 30–90 second field recordings (headphones, your own quiet workspace) and complete structured annotations: which instruments are present, tempo and key, timestamps of background events (traffic, sirens, applause), scene details
Compare paired recordings of the same song captured at different locations and judge what stayed the same and what changed
In later phases: review AI model descriptions of clips and mark what's correct, wrong, or invented, with a brief written explanation
Attend a paid onboarding/calibration session and a short weekly sync
Who we're looking for (any of these backgrounds)
Working or gigging musicians, session players, producers, or mixing engineers
Music educators, ear-training instructors, band/choir directors, conservatory students or graduates
Location sound recordists, sound designers, foley artists, or podcast/documentary audio editors
Requirements
3+ years of hands-on music or audio experience
Strong analytical listening: you can pick individual instruments out of a busy, noisy, real-world mix — not just studio recordings
Can identify tempo (within a few BPM) and musical key (relative pitch with a reference is fine)
Comfortable with detail-oriented, repetitive annotation work in a web platform — dropdowns, timestamps, short structured notes
Clear written English for brief, evidence-based notes (e.g., "accordion enters around 0:12")
Quality headphones, quiet workspace, reliable internet
Available 20–25 hrs/week for the engagement window
Application screening questions

Can you commit to 20–25 hrs/week for the full engagement window, plus a onboarding live session and a weekly sync?
What specific headphone or monitor model(s) do you use for detailed listening work?
