Kif huwa magħmul il-punteġġ tal-plejbek tal-awdjo
L-inġiniera ta’ SBMARK jittestjaw id-daqq permezz ta’ kelliema tal-ismartphone, li l-prestazzjoni tagħhom tiġi evalwata fil-laboratorji tagħna u taħt kundizzjonijiet tal-ħajja reali, billi jużaw apps u settings awtomatiċi.
Playback performance is also very good, although it sounds a little aggressive at high volumes. The Galaxy A33 5G benefits from a well-balanced tone, with a clear mid-range and quite satisfying bass. The bass performance is surprisingly solid, with a round sound and a good presence. The midrange is homogeneous, providing good clarity and sufficient warmth. The highs sound clear and bright enough. The A33 5G is not as consistent at different volume levels. The A33 does a good job of preserving its tonal balance at softer volumes, despite a slight loss of bass. But at maximum volume the highs tend to sound somewhat piercing and aggressive. In the dynamics attribute, the A33 5G performs well and consistently regardless of the volume level. The attack is precise and snappy. With a realistic envelope in the low end, bass accuracy is very satisfying. Considering the spatial performance, the sthe rendering of the tereus scene is both accurate in terms of localizability and wide enough for a device of this size. The stereo image does not rotate according to the orientation of the phone. The Left / Right balance seems well centered. Remote rendering is realistic; the voices seem to come from the right position. Volume performance is slightly below average. Although the maximum volume is correct, it appears to be unstable depending on the content, possibly due to a security algorithm. The Galaxy A33 5G offers a very clean playback experience, mostly free of artifacts. The speakers are well positioned to avoid clogging.

Here’s how the Samsung Galaxy A33 5G fares in playback use cases compared to its competitors:
Il-punteġġ tat-Timbre jirrappreżenta kemm telefon jirriproduċi l-ħoss fil-firxa tonali li tinstema' u jqis id-dipendenza tal-bass, midrange, treble, bilanċ tonali u volum. Huwa l-aktar attribut importanti għar-riproduzzjoni.
Il-punteġġ Dynamics ikejjel l-eżattezza tal-bidliet fil-livell tal-enerġija tas-sorsi tal-ħoss, bħall-preċiżjoni li biha tiġi riprodotta nota tal-bass jew il-ħoss tal-impatt tat-tnabar.
Attributi sekondarji għal testijiet spazjali jinkludu l-identifikazzjoni tal-pożizzjoni ta 'ħoss speċifiku, il-bilanċ pożizzjonali tiegħu, id-distanza u l-amplitudni.
Il-punteġġ tal-volum jirrappreżenta l-volum ġenerali ta 'smartphone u kif il-volum jiżdied u jonqos gradwalment abbażi tal-input tal-utent.
Hawn huma xi livelli ta' pressjoni tal-ħoss (SPLs) imkejla meta nilqgħu r-reġistrazzjonijiet kampjuni tagħna ta' hip-hop u mużika klassika fil-volum massimu:
| Hip hop | Classic | |
| Samsung Galaxy A33 5G | 74.3 dBA | 69.3 dBA |
| Samsung Galaxy A52 5G | 72 dBA | 68.3 dBA |
| Google Pixel 6 | 74.8 dBA | 69.7 dB |
Il-grafika hawn taħt turi l-bidliet gradwali fil-volum minn minimu għal massimu. Nistennew li dawn il-bidliet ikunu konsistenti fil-firxa kollha, sabiex il-livelli kollha tal-volum jaqblu mal-aspettattivi tal-utent:
Il-punteġġ Artifacts ikejjel il-punt sa fejn il-ħoss huwa affettwat minn diversi tipi ta 'distorsjoni. Aktar ma jkun għoli l-punteġġ, inqas ħoss tinnota. Distorsjoni tista 'sseħħ minħabba l-ipproċessar tal-ħoss fl-apparat u l-kwalità tal-kelliema.
Kif huwa magħmul il-punteġġ tal-plejbek tal-awdjo
L-inġiniera ta' SBMARK jittestjaw ir-reġistrazzjoni billi jevalwaw il-fajls irreġistrati fuq tagħmir awdjo ta' referenza. Dawn ir-reġistrazzjonijiet isiru fil-laboratorji tagħna u f'kundizzjonijiet tal-ħajja reali, bl-użu ta 'apps u settings predefiniti.
The A33 5G is a clever recording device, capturing and delivering top-notch tone with its microphones. When recording at high SPL, the A33 5G offers a good tonal balance, thanks to pleasant warmth and low-end extension, but remains slightly dark due to the lack of high-end extension. When recording in normal environments with life video and selfie apps, the performance is still very good, producing a good tonal balance. That tonal balance could benefit from increased brightness, high-end extension, and clarity in the mid-to-high range. Using the memo app, tonal balance is compromised by the lack of low treble and can sound tinny and unnatural. In the registration dynamics attribute, tThe Galaxy A33 5G provides very good SNR in all tested use cases; the background is well subdued. The envelope rendition is quite precise, with a sharp attack and precise explosives, except in selfie video mode, where the envelope rendition is slightly reduced by compression, resulting in a more rounded attack. At high SPL, dynamic performance is still good, thanks to a fairly accurate envelope rendering and a pleasantly snappy attack. Considering the spatial performance, the A33 5G offers good localizability. The amplitude is also good, which allows a very realistic stereo rendering, even in selfie video mode, where the amplitude remains better than average. Remote performance is compromised by an unnatural midrange that tends to drive voices away but nevertheless remains realistic. Memo app recordings are mono. The device offers medium performance in the volume attribute. The recording volume is good in all use cases. The A33 5G performs well in high SPL scenarios; the distortion, while present, is barely noticeable. The performance of the artifacts is average. Keep in mind that microphones easily clog completely and are sensitive to finger noises that induce large drops in volume. The background rendering is skillful.
Here’s how the Samsung Galaxy A33 5G fares in recording use cases compared to its competitors:
Il-punteġġ tat-Timbre jirrappreżenta kemm telefon jaqbad ħsejjes fil-firxa tonali li tinstema' u jqis il-bilanċ tal-bass, midrange, treble u tonal. Huwa l-aktar attribut importanti għar-reġistrazzjoni.
Il-punteġġ Dynamics ikejjel l-eżattezza tal-bidliet fil-livell tal-enerġija tas-sorsi tal-ħoss, bħal kemm huma riprodotti b'mod preċiż l-isplussivi ta 'vuċi (p, tek, per eżempju). Il-punteġġ iqis ukoll il-Proporzjon tal-Ħsejjes għall-Istorbju (SNR), bħal kemm il-vuċi prinċipali hija qawwija meta mqabbla mal-istorbju fl-isfond.
Attributi sekondarji għal testijiet spazjali jinkludu l-identifikazzjoni tal-pożizzjoni ta 'ħoss speċifiku, il-bilanċ pożizzjonali tiegħu, id-distanza u l-amplitudni fuq fajls awdjo rreġistrati.
Il-punteġġ tal-volum jirrappreżenta l-livell ta 'normalizzazzjoni tal-awdjo fuq il-fajls irreġistrati u kif l-apparat jimmaniġġa ambjenti storbjużi, bħal kunċerti elettroniċi, waqt ir-reġistrazzjoni.
Hawn huma l-livelli tal-ħoss irreġistrati fil-fajls tal-awdjo u tal-vidjo, imkejla f'LUFS (Loudness Unit Full Scale); bħala referenza, nistennew li l-livelli ta' loudness ikunu ogħla minn -24 LUFS għall-kontenut irreġistrat:
| Laqgħa | Video tal-ħajja | Video selfie | Memo | |
| Samsung Galaxy A33 5G | -25.9 LUFS | -22 LUFS | -20.9 LUFS | -21.4 LUFS |
| Samsung Galaxy A52 5G | -26.1 LUFS | -22.3 LUFS | -20.8 LUFS | -21.5 LUFS |
| Google Pixel 6 | -27.8 LUFS | -17.9 LUFS | -16.3 LUFS | -19.8 LUFS |
L-Artifacts Score ikejjel sa liema punt il-ħsejjes irreġistrati huma affettwati minn diversi tipi ta’ distorsjonijiet. Aktar ma jkun għoli l-punteġġ, inqas ħsejjes tinnota. Jistgħu jseħħu distorsjonijiet minħabba l-ipproċessar tal-ħoss fl-apparat u l-kwalità tal-mikrofoni, kif ukoll l-immaniġġjar tal-utent, bħall-mod kif jinżamm it-telefon.
Isma' dwar l-artifacts f'din is-silta, li ġiet irreġistrata f'ambjent domestiku b'ritmu mgħaġġel:
L-isfond jevalwa kif naturalment il-ħsejjes varji madwar taħlita ta 'vuċi fil-fajl ta' reġistrazzjoni tal-vidjo. Pereżempju, meta tirreġistra diskors f'avveniment, l-isfond m'għandux jinterferixxi mal-vuċi prinċipali, iżda għandu jipprovdi kuntest għall-ambjent tal-madwar.
