- Generally good signal-to-noise ratio and accurate envelope, except with the recorder app
- Good tonal capabilities, but inconsistent across use cases
Kontra
- Slightly disappointing audio zoom, barely noticeable lateral rejection
- Very sensitive to wind with memo app
- Main problems when recording at high sound pressure levels
Google Pixel Fold performed very well in SBMARK audio tests. With a Playback score of 135, it’s the best foldable device we’ve tested to date for audio playback, thanks to a pleasant sound signature from the built-in speakers. It worked best when playing music, but it also worked well with movie content and when playing games.
In recording, the Pixel Fold was best for recording with the front camera folded. Performance is slightly degraded when opening the device and recording with the main camera, and even more when using the recorder app, which only allows monaural recording. Across all recording apps, microphones were mostly unaffected by wind noise or device handling, but lack of consistency across use cases prevented a better recording score.
Our testers were also not slightly impressed with the spatial performance in both playback and recording. However, with the Pixel Fold’s large size in its unfolded state, it should have been able to get a wider stereo output. Instead, it joined the list of foldable devices that can’t convert its form factor into an audio performance advantage.

Kif huwa magħmul il-punteġġ tal-plejbek tal-awdjo
L-inġiniera ta’ SBMARK jittestjaw id-daqq permezz ta’ kelliema tal-ismartphone, li l-prestazzjoni tiegħu tiġi evalwata fil-laboratorji tagħna u taħt kundizzjonijiet tal-ħajja reali, bl-użu ta’ apps u settings issettjati minn qabel.
On playback, the Pixel Fold offered good overall tonal balance, focused primarily on the upper midrange and lower treble. This resulted in good clarity of most musical content, but a lack of high end extension was evident on instruments such as cymbals. Bass was decent, thanks to the good upper bass. However, low-end extension was pretty poor. Dynamic performance was good, with crisp, accurate attack and decent bass accuracy. The punch was also good, but could have done with a touch more low-to-mid energy.
The Google device also delivered decent width, but the audio scene didn’t extend beyond the physical form of the device, and given the phone’s large (unfolded) size, our testers expected something better. The balance was good but slightly offset up. Individual sound sources were easy to spot in the audio scene, and both distance and depth rendering were accurate. Our experts have found the minimum volume to be too low, making it difficult to hear quiet passages in highly dynamic content, such as classical music. Maximum volume was quite loud, however, and while volume consistency was good, our testers found the upper steps stalled. In terms of unwanted audio artifacts, our team noticed significant compression at maximum volume and heavy aliasing.

Kif huwa magħmul il-punteġġ tar-reġistrazzjoni tal-awdjo
L-inġiniera ta 'SBMARK jittestjaw ir-reġistrazzjoni billi jevalwaw fajls irreġistrati fuq tagħmir awdjo ta' referenza. Dawn ir-reġistrazzjonijiet isiru fil-laboratorji tagħna u taħt kundizzjonijiet tal-ħajja reali, bl-użu ta 'apps u settings default.
When recording, the Pixel Fold had a nice timbre, especially when recording with the selfie camera. However, it lacked some brilliance with the main camera, and our testers also noticed dull highs when recording loud events, such as concerts. Bass was also not enough with the main camera. Like the timbre, the dynamic performance was slightly dependent on the use case. The results were best when recording with the selfie camera in the folded state of the device, with a precise envelope, sharp attack and excellent signal-to-noise ratio. The dynamic results decreased slightly when recording with the main camera and the device open, and even more with the memo app.
In terms of space, Google delivered good location and distance rendition with most apps, except for the recorder app, which doesn’t allow for stereo recording. Recording volume was decent overall, but could have been better in all use cases. Under most recording conditions, Google was virtually free of unwanted audio artifacts. However, when recording concerts or other events with high SPLs, our testers noted distortion, fairly strong compression, and a slight pumping. Background rendering was natural and artifact-free in all use cases, but lacked bass and depth most of the time.
Here’s how the Google Pixel Fold fares in recording use cases compared to its competitors:
Użu punteġġ każ
It-Timbre Score jirrappreżenta kemm telefon jaqbad ħsejjes fil-firxa tonali li tinstema' u jqis il-bass, mids, treble, u l-bilanċ tonali. Huwa l-aktar attribut importanti għar-reġistrazzjoni.
Reazzjoni tal-frekwenza tal-vidjo tal-ħajja
Grafika tar-rispons tal-frekwenza ta’ 1/12-il ottava, li tkejjel il-qawwa ta’ kull frekwenza maqbuda mill-ismartphone tiegħek waqt li tirreġistra mewġa sine pura f’ambjent anekoiku.
Id-Dynamics Score ikejjel l-eżattezza tal-bidliet fil-livell tal-enerġija tas-sorsi tal-ħoss, bħal kemm jiġu riprodotti b'mod preċiż il-plożivi f'vuċi (p, t, k, per eżempju). Il-punteġġ iqis ukoll il-proporzjon tas-sinjal għall-istorbju (SNR), bħal kemm il-vuċi taċ-ċomb hija qawwija meta mqabbla mal-istorbju fl-isfond.
Attributi sekondarji għall-ittestjar spazjali jinkludu l-illokalizzazzjoni tal-post ta 'ħoss speċifiku, bilanċ pożizzjonali, distanza, u amplitudni fuq fajls awdjo rreġistrati.
Direttezza tar- reġistrazzjoni
Graff tad-direttività tal-ismartphone waqt li jirreġistra sinjali tat-test bl-użu tal-app tal-kamera, bil-kamera prinċipali. Jirrappreżenta l-enerġija akustika (f'dB) fuq l-angolu ta 'inċidenza tas-sors tal-ħoss. (Normalizzat għal angolu ta' 0°, quddiem l-apparat.)
Il-punteġġ tal-loudness jirrappreżenta kemm l-awdjo qawwi huwa normalizzat fuq fajls irreġistrati u kemm l-apparat jimmaniġġa tajjeb 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 tal-volum ikunu ogħla minn -24 LUFS għall-kontenut irreġistrat:
| Laqgħa | Videos ħajja | Selfie videos | Memorandum | |
| Google Pixel Itwi | -27.8 LUFS | -20.5 LUFS | -18.7 LUFS | -22 LUFS |
| Samsung Galaxy Z Fold4 | -25.8 LUFS | -21.6 LUFS | -22.7 LUFS | -21 LUFS |
| Oppo Sib N2 | -25 LUFS | -21.3 LUFS | -19.1 LUFS | -18.3 LUFS |
Il-punteġġ Artifacts ikejjel sa liema punt il-ħsejjes irreġistrati huma affettwati minn diversi tipi ta 'distorsjonijiet. Aktar ma jkun għoli l-punteġġ, inqas ikun hemm disturbi tal-ħoss notevoli. Jistgħu jseħħu distorsjonijiet minħabba l-ipproċessar tal-ħoss fl-apparat u l-kwalità tal-mikrofonu, kif ukoll l-immaniġġjar tal-utent, bħal kif jinżamm it-telefon.
F'dan il-paragun tal-awdjo, tista' tisma' kif dan l-ismartphone jimmaniġġja l-istorbju tar-riħ meta mqabbel mal-kompetituri tiegħu:
