Audio Expert for Polyphonic Transcription with MusicXML and Python
Overview
Global, fully remote contractor role for an Audio Expert focused on polyphonic transcription and music notation. You’ll work on an AI training project that analyzes mixed audio to reconstruct exact scores, including separating four SATB lines from mono recordings and delivering precise MusicXML. The position values strong listening, notation, and problem-solving skills over years of experience, with flexible hours and a variable weekly workload. Expect to use Python for audio inspection and to validate transcriptions against musical checks. Key work revolves around transcribing polyphonic recordings and generating accurate notation from audio data, with compensation tied to task completion and a minimum weekly submission requirement. MusicXML, Python, and polyphonic transcription are central to the role.
What You'll Do8
- 1Transcribe polyphonic recordings into structured musical notation.
- 2Isolate soprano, alto, tenor, and bass lines from a mono mix for clear separation.
- 3Identify pitches, onsets, durations, rests, and re-articulations with precision.
- 4Align events to the correct rhythmic grid through quantization.
- 5Apply appropriate key signatures and enharmonic spellings to ensure accurate notation.
- 6Create or adjust MusicXML data and support its manipulation.
- 7Use Python to inspect audio, analyze spectral content, and automate steps in the transcription workflow.
- 8Review and validate completed transcriptions through structured checks and possible resynthesis.
Requirements4
- 1Strong Python programming ability.
- 2Advanced ear training for polyphonic transcription like SATB arrangements.
- 3Solid understanding of harmony, rhythm, voice leading, and standard notation conventions.
- 4Experience with SATB music, choral arranging, score preparation, or similar polyphonic transcription work.
Who Should Apply
The ideal candidate is a musician or researcher who can demonstrate precise transcription of polyphonic music and comfort with MusicXML, supported by Python automation. This role may be less suitable for candidates without strong ear training or those who lack experience in SATB transcription or music notation processing. Common rejection factors include insufficient Python experience or limited ability to distinguish multiple vocal lines from a mono recording, and a lack of familiarity with music notation concepts such as key signatures and enharmonic spelling.
Salary Insight
Pay is per task and scales with project requirements; the rate falls between 50 and 100 USD per hour as stated, with no added salary figures beyond the task-based structure.
