How to test smartphone audio recording?

People are using their smartphones to create ever more video content. Smartphone camera image quality has greatly improved over the years, but what about the sound quality of the microphones? DXOMARK has developed a unique set of rigorous test protocols that mirrors the experience of people who use their smartphones to record audio input.

Inside our specially-commissioned laboratory at our headquarters in Paris, France, our audio engineers use a series of multimedia and audio samples that represent the full range of a user’s experience when recording and playing back the sound on speakers. We use these real-world examples, called use cases, as the basis for evaluating the audio input of each and every device under test to ensure fair comparisons.
