Today, DxOMark audio testing has been introduced to the services of the company. So far, the company has made a name for itself as the go-to source for smartphone cameras’ in-depth, unbiased testing and now it hopes to achieve the same reputation in testing smartphone speakers and microphones.
Five smartphones began the DxOMark audio test.
The company explained why it made the move in a blog post.
The company is testing playback performance against five criteria and recording against the same criteria plus how well it handles background noise.
- Timbre (frequency response, treble/midrange/bass, total balance, volume dependency)
- Dynamics (attack, bass precision, punch, volume dependency)
- Spatial (wideness, balance, distance, localization)
- Volume (maximum, minimum, user volume consistency)
- Artefacts (noise, pumping, clipping, user artefacts, other artefacts)
- [Recording] Background noise (directivity, noise profile, artefacts)
Interestingly the company says it needs to include audio expert perceptual data as well as measurements, but they claim that they are just as scientific.
Audio testing by DxOMark – initial results
And the results of the DxOMark audio testing first round? Top ranking goes to the Huawei Mate 20 X, 75 ahead of the second-placed iPhone. What’s surprising however, is the second place for the older iPhone XS Max, ahead of the new iPhone 11 Pro Max.
The stereo mics from the Mate gave it a great advantage, so it’s interesting that the iPhones were so close behind.
