Xiaomi 13T Pro Audio teszt

A Xiaomi 13T Pro szigorú SBMARK Audio tesztcsomagunkon keresztül mérjük 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 (elülső, oldalsó felső)
• Nincs Jack audio kimenet
• Dolby Atmos technológia

Visszajátszás

Bejegyzés

In SBMARK Audio tests, the Xiaomi 13T Pro delivered a fairly average performance and ranked behind its predecessor, the 12T Pro. Overall, the 13T Pro did better in recording than in playback, mainly due to inconsistencies in performance stereo with built-in speakers, which also sounded slightly harsh. But on the bright side, the audio was almost free of unwanted artifacts. Playback performance was better when listening to music and playing games, but slightly worse when watching movies.

Audio recordings had excellent volume and were overall best in office environments. In terms of audio recordings on video, the results were better with the selfie camera in portrait orientation than with the main camera in landscape.

Teszt összefoglaló

Az SBMARK hangtesztekről: A pontozáshoz és elemzéshez az okostelefon-audio áttekintéseinkben az SBMARK mérnökei objektív tesztek sorozatát hajtják végre, és több mint 20 órányi észlelési értékelést végeznek ellenőrzött laboratóriumi körülmények között.

The following section compiles key elements of our comprehensive testing and analysis performed in SBMARK laboratories. Detailed performance evaluations in the form of reports are available upon request. Do not hesitate to contact us.

The 13T Pro’s playback had a medium timbre, with a tonal balance that had a noticeable emphasis on the upper-midrange and treble. The treble had a certain brightness that didn’t sound natural, but more sibilant and harsh. The midrange lacked warmth, and while the bass presence somewhat compensated for the lack of low-midrange, the upper bass was quite fuzzy and the low-end extension wasn’t deep enough. Dynamic performance was good, though, with fairly crisp attack, proper bass accuracy, and pretty good punch.

Spatial test results were mediocre, with an average stereo scene width and a weak left channel, as well as a hole in the center of the stereo image. As a result, individual sound sources couldn’t be pinpointed precisely, and distance rendering wasn’t particularly accurate either, with voices often sounding slightly distant. The distribution of volume levels could have been more consistent, and the minimum volume setting was too low, making it difficult to hear low-volume passages in highly dynamic content, such as classical music. The maximum volume was quite high. In normal use, audio artifacts were very well under control, with only some slight distortion and slight pumping at maximum volume. Our experts also noted that the bottom speaker could easily be blocked during gaming, but other than muting the right channel, this wasn’t detrimental to the audio experience.

Íme néhány hangnyomásszint (SPL), amelyet a hip-hop és klasszikus zene mintafelvételeinek maximális hangerőn történő lejátszásakor mértek:

A következő grafikon a hangerő fokozatos változásait mutatja a minimumról a maximumra. Elvárjuk, hogy ezek a változtatások következetesek legyenek az egész tartományban, hogy minden mennyiségnövekedés megfeleljen a felhasználói elvárásoknak:

The Xiaomi did relatively better in recording than in playback. The tone of the recording was good, with satisfying highs, good midrange and decent bass performance. Dynamic performance was also quite good, despite slightly inconsistent envelope performance between use cases. With the main camera in landscape orientation, envelope accuracy was severely affected by compression and pumping, particularly when recording concerts. The sharpness of the mount was noticeably better with the selfie camera and the memo app. The signal-to-noise ratio was decent when recording in urban environments, but even better in quiet environments, such as in your home or office.

The width of the recorded stereo scene was great with the Memo app, but less so with the main or selfie camera. Despite some occasional blurriness, localizability was very good in all use cases. Distance performance was quite realistic and overall volume was excellent despite some slight volume variations evident when leaving an indoor environment during recording. The results were poor even at high sound pressure levels, for example during concerts. Under such conditions, our testers also observed strong pumping and distortion. Additionally, there was a loud hiss on all recording apps except the Memo app. The tonal balance of the background was natural, with good intelligibility of the main signal.

Itt vannak az audio- és videofájlokban rögzített hangszintek, LUFS-ben (Loudness Unit Full Scale) mérve; Referenciaként azt várjuk, hogy a hangerő szintje meghaladja a -24 LUFS-t a rögzített tartalomnál:
