Xiaomi Mix Fold 3 Audio teszt

A Xiaomi Mix Fold 3-at szigorú SBMARK Audio tesztcsomagunkon keresztül teszteltük, hogy megmérjük a teljesítményét a beépített mikrofonokkal történő hangrögzítés és a hangszórókon keresztüli lejátszás során.
Ebben az áttekintésben lebontjuk, hogyan teljesített különféle tesztek során, és számos gyakori használati esetet.

Áttekintés

A legfontosabb hangspecifikációk a következők:

• Két hangszóró (felső, alsó, mindkettő ugyanazon a felén)
• Nincs jack audio kimenet

Visszajátszás

Bejegyzés

With an overall score of 130, the Xiaomi Mix Fold 3 performed well in the SBMARK Audio tests and showed very noticeable improvements compared to its predecessor, the Mix Fold 2. The Mix Fold 3 especially shone as a recording device, thanks to a very pleasant timbre design and very effective wind noise reduction. Only when recording high-volume events, such as concerts, did the Xiaomi show some weaknesses. Overall recording results were better with the main camera, but the front camera and the memo app were almost at the same level.

Playback wasn’t at the same high level as the recording results, but still decent. Playback quality was very good at high volumes, with excellent bass and treble rendition as well as dynamics, but unfortunately the quality dropped at nominal and low volume levels. Like many other foldable devices, the Mix Fold 3 did not take full advantage of its form factor, with the integrated speakers positioned on the same half, playback was monophonic vertically, while the large size of the device would have suggested a wider sound and better performance overall space.

Playback performance was decent overall, with mostly good tone. Tonal balance was undoubtedly the device’s main issue, with both treble and bass appearing rather weak compared to the midrange. That said, the results were drastically better at maximum volume, with the highs and lows gaining enough strength to improve the overall tone. At nominal volume, however, the midrange was quite thin and the bass was overall lacking, particularly in terms of low-end extension.

Dynamic performance was good, especially at high volume. Attack was weak at low volume, but decent at nominal volume and very good at maximum volume. Punch and bass accuracy behaved slightly differently. Both were good at nominal volume but didn’t improve at high volume settings. Spatial performance was slightly disappointing, especially considering the large size of the Mix Fold3 when unfolded. With both speakers installed on the same half of the device, the Mix Fold 3 didn’t take advantage of its size to deliver stereo output in portrait orientation. The stereo image also didn’t adapt to the device’s rotations in the default music and video apps, and the stereo balance of the speakers didn’t seem to be exactly perfect, as the bottom speaker seemed slightly quieter than its top counterpart. Overall, the amplitude was disappointing and the localizability of individual sound sources seemed blurry and imprecise. Remote delivery was also not entirely realistic.

The maximum volume was quite high and the distribution of volume levels was quite consistent, but our experts felt that the minimum volume setting was too low. Audio artifacts were very well under control, with no noticeable distortion or excessive compression. However, with a natural hand position when holding the device, the speakers were subject to some occlusion.

The Xiaomi Mix Fold 3 provided excellent recording performance overall, although tonal balance varied depending on the use case. Recordings from the main camera provided clear and precise treble, offering good intelligibility of voices. However, the highs lacked clarity when recording with the front camera. The midrange was very good with all recording apps, but could seem slightly weak in some urban scenarios. At high sound pressure levels, such as when recording loud concerts, the tonal balance was much less consistent, with dark and almost muffled trebles and mids lacking fullness.

The signal-to-noise ratio was quite good with the main and selfie cameras, thanks to the noise reduction algorithm which did a great job, especially in domestic environments. However, when using the memo application in an urban setting, the background was quite noisy and hindered intelligibility. Envelope performance generally offered a crisp, precise attack, except in concert use where envelope accuracy was compromised by heavy compression.

The breadth of the recorded sound scene was very good with the main camera, and the localizability of individual sound sources was very precise. Range remained good with the Memo app, but was a little more limited when recording with the front camera. Remote performance was excellent across all recording apps and use cases. Volume was adequate in recordings made with the main and front cameras, but slightly weaker with the Memo app. The recordings were mostly free of artifacts, except for slight clipping on sudden loud vocals. Background rendering was excellent, with no noticeable artifacts.

Our engineers expected the Mix Fold 3’s audio zoom feature to perform better. The noticeable lateral rejection present by default did not improve with zoom level and, instead, boosted low-end signals such as background noise. The wind noise reduction feature, however, proved to be extremely effective; our experts found the DSP to be well calibrated and adequately improve intelligibility in windy conditions.
