Abstract
This application discloses a method, apparatus, device, and storage medium for testing the audio playback response time of a vehicle cabin, relating to the field of vehicle cabin function testing technology. The method for testing the audio playback response time includes: acquiring a test file, which is obtained by recording the testing process of an audio test file in a device under test; reading the test file, acquiring the audio playback click time, and monitoring the loudness and frequency of the test file; determining the audio response time when both the loudness and the frequency reach preset values; and determining the audio playback response time based on the audio playback click time and the audio response time. This application can improve the accuracy of vehicle cabin audio playback response time testing.
