Audio Expert
Pay: $50–$100/hour Location: Global, fully remote Job Type: Contractor (~15 hrs a week) Location: Remote Schedule: Flexible, you pick the hours and days (including weekends if desired) Relevant expertise matters more than years of experience We are looking for a highly skilled music transcription expert to contribute to an AI training project involving polyphonic audio analysis, SATB transcription, music notation, and Python. The work involves reconstructing precise musical scores from mixed audio recordings. A representative task may require separating four simultaneous soprano, alto, tenor, and bass lines from a mono recording and converting the complete performance into an exact MusicXML score. This is not a general audio-production or speech-transcription role. Candidates should have strong musical listening, notation, and technical problem-solving abilities. What you’ll work on:
- Transcribe polyphonic musical recordings into structured notation.
- Distinguish soprano, alto, tenor, and bass lines from a mono mix.
- Identify pitches, onsets, durations, rests, and re-articulations.
- Quantize events to the correct rhythmic grid.
- Apply accurate key signatures, accidentals, and enharmonic spelling.
- Generate or manipulate MusicXML.
- Use Python to inspect audio, analyze spectral information, and automate parts of the transcription workflow.
- Validate transcriptions through musical review, structured checks, or resynthesis. Required qualifications:
- Strong Python programming ability.
- Advanced ear training and polyphonic music-transcription ability.
- Strong understanding of harmony, rhythm, voice leading, and standard notation.
- Experience with SATB music, choral arranging, score preparation, or a closely related form of polyphonic transcription. Relevant tools may include librosa, NumPy, SciPy, music21, Essentia, pretty_midi, MuseScore, or other audio-analysis and notation software. No specific tool is mandatory if your experience is transferable. Formal education and years of professional experience are not strict requirements. Experienced performers, arrangers, composers, choir musicians, researchers, and independent transcription specialists are encouraged to apply if they can demonstrate the relevant skills.
Process
- Apply to the role, filling out the screening questions
- Complete AI Interview (approx. 30 minutes)

Common questions
Can I apply to Micro1 from outside the US or UK?
Yes. Micro1 accepts applicants from most countries worldwide, unlike DataAnnotation or Outlier, both of which cap access to a handful of English-speaking countries. Most roles still require strong written and spoken English.
Does Micro1 monitor your computer while you work?
On many projects, yes, through time-tracking tools that take periodic screenshots to verify active hours. Check the specific project's requirements before accepting if desktop monitoring is a dealbreaker.
How is my creative work used in AI training?
As ground-truth data: for writers, that means creative generation samples; for voice actors, it often means training text-to-speech models. Check the specific contract details on rights usage for your voice or likeness before signing.
Do creative AI training roles allow creative freedom?
Some, within limits. You're hired for your talent, but most projects still require following strict style guides, like keeping a neutral tone or matching a technical-manual style. Consistency across the dataset matters more than personal expression here.
What does Voice Acting work look like for an Audio Expert?
Tasks here are scoped to Voice Acting, not generic labeling. As an Audio Expert, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Voice Acting) rather than following a one-size-fits-all rubric. If you don't have hands-on Voice Acting background, this is likely not the right listing to start with.
What specific skills does this listing call for?
MusicXML and Expert are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.
What does the 'openings' count on this listing mean?
It's Micro1's live count of how many candidates it's still trying to place for this specific role, 10 right now, not a countdown on your individual application. A higher number signals more active demand; it doesn't lower the bar for acceptance.
How much does this specific role pay?
This listing is posted at $50–$100/task, a per-task rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.
How does per-task pay translate to an hourly rate?
It doesn't directly, that's the catch. Each task has a listed price and an estimated completion time, but your actual effective rate depends on how fast you work. If a task is estimated at 20 minutes and pays $8, that is $24/hr for a fast worker and $12/hr for a slow one. Track your actual time on the first few tasks before treating the listed rate as your real hourly income.
What happens when I click Apply on this listing?
You'll be taken to Micro1's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.
