Microphone and loudspeaker sweep and loopback test tools

Applicable purchasers

AITerminal, camera, audio, display and wearable OEM

Test and assembly objects

Audio modules, reference source microphones and fixtures

Development and delivery

Control playback of recordings and sweeps, and associate acoustic references, delays and abnormal channels

Project input

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

Acceptance method

Fixed sound source/reference microphone, geometric coupling and environment, checked playback recording configuration, sweep response, original audio and loopback channel abnormalities.

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.
