Music and Audio Annotation Expert

You will listen to 30-90 second field recordings through quality headphones and turn what you hear into structured information. The work covers music, background sounds, recording context, and real-world events.

You will also compare recordings of the same song made in different places, then review AI-generated descriptions of audio clips in later phases.

• Identify instruments, tempo, musical key, background sounds, crowd reactions, and other scene details.
• Add timestamps for events such as traffic, sirens, and applause.
• Write concise notes in a web-based annotation platform using dropdowns, timestamps, and structured fields.
• Compare paired recordings and judge which characteristics stay consistent or change.
• Mark AI-generated audio descriptions as correct, incorrect, or invented, with brief explanations based on what you heard.
