About AI Training and Audio Classification

AI training is the human side of building artificial intelligence. People prepare and review examples that help AI systems understand the world, including audio recordings, spoken language, music, and other sound data.

In this project, your musical expertise will help an AI system learn to identify instruments from short audio clips. Careful human classification and consistent feedback are essential for producing useful training data.

• Work directly on data used to improve AI systems
• Apply real-world musical listening expertise
• Contribute to a fast-growing field with flexible remote work

The Role

OpenTrain is seeking a Music Instrument Audio Evaluator for a short-term Music Instrument Audio Classification project. You will listen to short clips, identify the instrument family and specific instrument, and evaluate AI-generated audio data using your subject-matter knowledge.

Prior AI training experience is not required unless stated elsewhere on this job page. The key qualification is strong real-world knowledge of music and the ability to recognize instruments accurately by sound.

• Project length: Short-term, with a two-day work window
• Time requirement: 20+ hours per week
• Schedule: Flexible
• Pay: $160 fixed price
• Engagement: Contractor and part-time

What You'll Do

You will complete focused audio classification tasks using provided references and clear annotation guidelines. Consistency, accuracy, and careful listening will be important throughout the project.

• Listen to short audio clips of musical instruments
• Identify the instrument family, such as strings, brass, woodwind, percussion, or keyboard
• Identify specific instruments within each family
• Use provided audio references to guide classification decisions
• Follow annotation guidelines and deliver consistent, accurate work
• Evaluate and improve AI-generated audio data based on your expertise

Requirements
