Carane skor puter maneh audio dumadi
Insinyur SBMARK nguji puter maneh liwat speaker smartphone, sing kinerja dievaluasi ing laboratorium lan ing kahanan nyata, nggunakake aplikasi lan setelan gawan.
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.

Mangkene carane regane Samsung Galaxy A33 5G ing kasus panggunaan puter maneh dibandhingake karo pesaing:
Skor Timbre nggambarake carane telpon ngasilake swara ing jangkoan tonal sing bisa dirungokake lan njupuk bass, midrange, treble, keseimbangan tonal lan katergantungan volume. Iki minangka atribut sing paling penting kanggo reproduksi.
Skor Dynamics ngukur akurasi owah-owahan ing tingkat energi sumber swara, kayata presisi karo cathetan bass utawa swara impact drum diprodhuksi maneh.
Atribut sekunder kanggo tes spasial kalebu ngenali posisi swara tartamtu, keseimbangan posisi, jarak lan amplitudo.
Skor volume nggambarake volume sakabèhé saka smartphone lan carane volume mundhak lan suda adhedhasar input pangguna.
Ing ngisor iki sawetara tingkat tekanan swara (SPL) sing diukur nalika muter rekaman sampel musik hip-hop lan musik klasik kanthi volume maksimal:
| Hip-Hop | Klasik | |
| Samsung Galaxy A33 5G Kab | 74.3 dBA | 69.3 dBA |
| Samsung Galaxy A52 5G Kab | 72 dBA | 68.3 dBA |
| Google Pixel 6 | 74.8 dBA | 69.7 dB |
Grafik ing ngisor iki nuduhake owah-owahan bertahap ing volume saka minimal nganti maksimal. Kita ngarepake owah-owahan iki konsisten ing jangkoan, supaya kabeh tingkat volume cocog karo pangarepan pangguna:
Skor Artefak ngukur tingkat sing kena pengaruh swara saka macem-macem jinis distorsi. Sing luwih dhuwur skor, sing kurang gangguan sampeyan sok dong mirsani. Distorsi bisa kedadeyan amarga pangolahan swara ing piranti lan kualitas speaker.
Carane skor puter maneh audio dumadi
Insinyur SBMARK nguji rekaman kasebut kanthi ngevaluasi file sing direkam ing peralatan audio referensi. Rekaman kasebut ditindakake ing laboratorium lan ing kahanan nyata, nggunakake aplikasi lan setelan sing wis ditemtokake.
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.
Mangkene carane regane Samsung Galaxy A33 5G nalika ngrekam kasus panggunaan dibandhingake karo pesaing:
Skor Timbre nggambarake sepira apike telpon njupuk swara ing jangkoan tonal sing bisa dirungokake lan njupuk keseimbangan bass, midrange, treble lan tonal. Iku atribut paling penting kanggo registrasi.
Skor Dynamics ngukur akurasi owah-owahan ing tingkat energi sumber swara, kayata sepira akurat bledosan swara (p, tek, contone) diprodhuksi. Skor kasebut uga nimbang Rasio Swara-kanggo-Noise (SNR), kayata sepira banter swara utama dibandhingake karo swara latar mburi.
Atribut sekunder kanggo tes spasial kalebu ngenali posisi swara tartamtu, keseimbangan posisi, jarak lan amplitudo ing file audio sing direkam.
Skor volume nuduhake tingkat normalisasi audio ing file sing direkam lan cara piranti nangani lingkungan sing rame, kayata konser elektronik, sajrone ngrekam.
Ing ngisor iki tingkat swara sing direkam ing file audio lan video, diukur ing LUFS (Loudness Unit Full Scale); minangka referensi, kita ngarepake tingkat swara luwih dhuwur tinimbang -24 LUFS kanggo konten sing direkam:
| Encounter | Video urip | video selfie | Memo | |
| Samsung Galaxy A33 5G Kab | -25.9 LUFS | -22 LUFS | -20.9 LUFS | -21.4 LUFS |
| Samsung Galaxy A52 5G Kab | -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 |
Skor Artefak ngukur sepira swara sing direkam kena pengaruh macem-macem jinis distorsi. Sing luwih dhuwur skor, sing kurang gangguan sampeyan sok dong mirsani. Distorsi bisa kedadeyan amarga pangolahan swara ing piranti lan kualitas mikropon, uga penanganan pangguna, kayata cara nyekeli telpon.
Rungokake artefak ing kutipan iki, sing direkam ing lingkungan omah sing cepet-cepet:
Latar mburi ngevaluasi carane alamiah macem-macem swara sak campuran swara menyang file rekaman video. Contone, nalika ngrekam pidato ing acara, latar mburi kudu ora ngganggu swara utama, nanging kudu menehi konteks kanggo lingkungan sekitar.
