Audio-video input-to-output latency test tools

Applicable purchasers

AITerminal, camera, audio, display and wearable OEM

Test and assembly objects

Terminal, observable photoacoustic triggering and acquisition reference

Development and delivery

Record input, display, and sound moments respectively, and output end-to-end time difference and jitter

Project input

Sound source/reference sensing, coupling fixtures, geometric environment, time base and sampling configuration

Acceptance method

Use the same time base to record observable light/acoustic input and output events, check triggering and sampling delays, and count time differences and jitter under repeated conditions.

Implementation steps

Object and interface verification → Reference link and solution confirmation → Single module prototype → Instrument and equipment joint debugging → Independent reference re-inspection → Source code, configuration and record delivery.

Equipment condition and scope confirmation

The scope may include control boards, firmware, instrument drivers, host software, process configuration and test records. Mechanical fixtures, pressure-bearing structures, fluid circuits, power circuits and optical or acoustic references are provided or separately designed by the responsible parties. Measurement specifications are established through validation with the target equipment and independent references.

Source code, design documents, instrument licensing, procurement, on-site support and ongoing maintenance scope are listed in the project documents.
