About the role: Role Title: Music & Sound Annotation Expert
Role Type: Contractor
Location:
Remote Our team 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
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
