DxOMark, a website that rates telephone and digital cameras, has introduced an audio score for phones. The score measures the recording and playback features of a phone.
The site tested seven devices from five brands for initial testing. The Huawei Mate 20 X leads the ranking, followed by the iPhone XS Max and the iPhone 11 Pro Max +.
DxOMark has built a bespoke silencer – a room that absorbs all sounds to test the capabilities of a's built-in microphones. Telephone – for testing recording and playback.
Engineers at the facility are mainly trying to test different scenarios, such as: Take a selfie video, a street performance, a concert or a meeting. In all these situations, different difficulties arise in audio recording. While it may be difficult for a telephone to record a high-volume or bass-free concert, a classic performance requires the timbre of each instrument to be selected. In a meeting, a phone should be able to record audio so that you can select individual voices.
The team also tests a phone's ability to handle background noise, the direction of the source sound, and the effect of recording based on how you hold your phone.
DxOMark has also set up a special listening room to test the phone's playback. Currently, only playback is measured through the phone's speakers. Scenarios like playing a game or sharing music with a group are tested, with a focus on the clarity of the sound.
While listening to sounds from a phone's speakers, the team at the site measures factors such as timbre, sound, balance, and volume. It is also observed how clean the sound is during playback, ie how it eliminates the noise or unwanted frequencies.
Just as with Dxomark's camera scores, you should not rate your audio scores at a face value and consider the tonal capabilities of a phone as the absolute benchmark. In addition, DxOMark uses perpetual (audio-listening) and objective (device-by-device) methods to assign a score to a phone. So there is plenty of room for discussion as to whether this is an ideal way to measure the audio quality of a phone.
