Playback

Pros

Cons

  • Significant lack of low-end extension
  • Spatial performance could have been better considering type/dimensions of device, especially in terms of wideness
  • Strong compression and significant distortion at maximum volume
  • Stalling upper volume steps

Recording

Pros

  • Very good resilience to wind with the main and selfie cameras, even in strong winds
  • Microphones not prone to occlusions and finger noises, artifacts generally well under control
  • In general good signal-to-noise ratio and accurate envelope, except with recorder app
  • Good timbre capabilities, but not consistent between use cases

Cons

  • Slightly underwhelming audio zoom, side-rejection barely noticeable
  • Very sensitive to wind with memo app
  • Major issues when recording at high sound pressure levels

The Google Pixel Fold delivered a very good performance in the DXOMARK Audio tests. With a playback score of 135, it  is the best foldable device we have tested to date for audio playback, thanks to a pleasant sound signature of the built-in speakers. It performed best when playing back music but also did well with movie content and when gaming.

In recording, the Pixel Fold was best for recording with the front camera. Performance dropped slightly when unfolding the device and recording with the main camera, and even more so when using the recorder app, which only allows for monophonic recording. Across all recording apps, the microphones were mostly unaffected by wind noise or handling of the device, but lack of consistency between use cases prevented a better recording score.

Our testers were also slightly unimpressed by the spatial performance in both playback and recording.  However, with the Pixel Fold’s  large dimensions in its unfolded state, it should have been capable of attaining a wider stereo rendition. Instead, it joined the list of foldable devices that cannot convert its form factor into an advantage in terms of Audio performance.

How Audio Playback score is composed

DXOMARK engineers test playback through the smartphone speakers, whose performance is evaluated in our labs and in real-life conditions, using default apps and settings.

In playback, the Pixel Fold offered an overall nice tonal balance that was mainly focused on the upper midrange and lower treble. This resulted in good clarity of most musical content but a lack of high-end extension was noticeable on instruments like cymbals. Bass was decent, thanks to good upper bass. Low-end extension was quite poor, though. Dynamic performance was good, with sharp and precise attack and decent bass precision. Punch was good as well, but could have done with a touch more low mid energy.

The Google device also delivered decent wideness, but the audio scene did not extend beyond the device’s physical shape, and given the large (unfolded) dimensions of the phone, our testers  expected something  better. Balance was good but slightly offset towards the top. Individual sound sources were easy to pinpoint in the audio scene, and both distance and depth rendering were accurate. Our experts found the minimum volume step too quiet, making it hard to hear soft passages in highly dynamic content, such as classical music. Max volume was loud enough, though, and while volume consistency was good, our testers found the upper steps to be stalling. In terms of unwanted audio artifacts, our team noticed significant compression at maximum volume and strong aliasing.

How Audio Recording score is composed

DXOMARK engineers test recording by evaluating the recorded files on reference audio equipment. Those recordings are done in our labs and in real-life conditions, using default apps and settings.

In recording, the Pixel Fold featured 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 treble when recording loud events, such as concerts. Bass was insufficient with the main camera as well. Like timbre, dynamics performance was slightly use case dependent. Results were best when recording with the selfie camera in the device’s folded state, with an accurate envelope, sharp attack and excellent signal-to-noise. Dynamics results somewhat dropped when recording with the main camera and the device unfolded, and even more so with the memo app.

In terms of spatial, the Google offered good localizability and distance rendition with most apps, except the recorder app, which does not allow for stereo recording. Recording loudness was overall decent but could have been better across all use cases. In most recording conditions, the Google was pretty much free of unwanted audio artifacts. However, when recording at concerts or other events with high sound pressure levels, our testers noticed distortion, pretty strong compression and slight pumping. Background rendition was natural and artifacts-free across all use cases, but lacked bass and depth most of the time.

Here is how the Google Pixel Fold performs in recording use cases compared to its competitors:

The Volume score represents how loud audio is normalized on the recorded files and the how the device handles loud environments, such as electronic concerts, when recording.

Here are the sound levels recorded in the audio and video files, measured in LUFS (Loudness Unit Full Scale); as a reference, we expect loudness levels to be above -24 LUFS for recorded content:
Meeting Life Video Selfie Video Memo
Google Pixel Fold -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 Find N2 -25 LUFS -21.3 LUFS -19.1 LUFS -18.3 LUFS

Artifacts

127

Google Pixel Fold

145

Black Shark 5 Pro

The Artifacts score measures the extent to which the recorded sounds are affected by various types of distortions. The higher the score, the less the disturbances in the sound are noticeable. Distortions can occur because of sound processing in the device and the quality of the microphones, as well as user handling, such as how the phone is held.

In this audio comparison, you can listen to the way this smartphone handles wind noise relative to its competitors:
