It is a professional evaluation algorithm for the listening quality of playback audio.
MDAQS is an AI-based method for evaluating audio quality using tools. It assesses the listening quality during acoustic playback in terms of timbre, distortion, and immersion, outputting the results as MOS values, enabling rapid evaluation and comparison. HEAD acoustics developed MDAQS (Multidimensional Audio Quality Score) based on specially designed listening tests tailored to specific needs. Algorithms trained on test results determine the audio quality of any playback system or device, such as speakers, headphones, headsets, in-car audio systems, mobile speakers, and smart speakers, outputting MOS values. This allows for quick and convenient evaluation of playback quality during and after development.

basic information
› Multi-channel speaker systems for vehicles and homes › Earphones, headphones, headsets › Smart speakers › Mobile speakers › One-piece multi-room speakers › Stereo audio systems As systems and devices become more complex, the development and tuning aimed at achieving excellent acoustic characteristics are becoming increasingly difficult. Basic measurements, such as frequency response, cannot reveal the overall quality of the system and are insufficient for predicting human auditory impressions. To achieve this, it is necessary to conduct auditory tests, but obtaining statistically significant results requires considerable labor costs and time. To meet the need for a quick and cost-effective solution for evaluating audio playback quality, HEAD acoustics has developed MDAQS - Multi-Dimensional Audio Quality Score. MDAQS is the first algorithm designed to evaluate the audio quality of any audio playback system or device using a tool.
