Freelance Mechanical & Real-World SFX Video Contributor (Remote)

AIxBlock is recruiting contributors to capture authentic real-world sound effects generated by mechanical objects, tools, vehicles, electronics, and other physical interactions.

Each recording must include video showing the sound-producing object or activity, together with its naturally synchronized audio.

Examples of Sounds

• Mechanical: Motors, fans, printers, pumps, gears, switches
• Tools: Hammering, drilling, sawing, tightening screws, operating hand tools
• Vehicles: Engine starting, car doors, turn signals, windshield wipers, vehicle movement

• Materials: Metal impacts, glass clinking, wooden objects, plastic containers
• Industrial: Workshop machinery, factory equipment, construction equipment where authorized and safe

Accepted Recording Devices

• Apple iPhone 12 or newer

• Avoid repeated recordings of identical sound events.
• Follow assigned sound categories and quotas.
