This is a database that implements comprehensive measurement and analysis functions for the evaluation of car audio systems.
HQS-Car-Audio is a test suite designed to perform performance testing and analysis of car audio systems using ACQUA. It targets both general car audio systems and high-end car audio systems. It also supports multi-point recording techniques necessary for detailed measurements. The test signals use common audio formats (*.wav, *.mp3). During playback, a connection to the car audio system via the labCORE hardware platform or a customized device is required. The test suite also incorporates move°S technology, which allows for extensive analysis through the rotation of a dummy head (HMS II Series). Furthermore, the excellent flexibility of the test suite enables the recording of audio data using a microphone array.
