Music & Sound Annotation Expert

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
