However, our testers expected better space performance, as the device is quite large when open and, in terms of volume, the Z Flip4 isn&#8217;t quite on par with some of its more conventional Samsung Galaxy cousins.<\/p>\n<p>As a recording device, the Z Flip4 works best for front camera and main camera recordings and is less recommended for office and clipboard recordings, mainly because it defaults to mono recording when using the corresponding apps.  On top of that, recordings made with the Samsung offer good timbre in most use cases, as well as excellent signal-to-noise ratio and distance rendering.  Among the disadvantages, wind noise reduction is not very effective and the device does not have an audio zoom function.<\/p><div id=\"forum-1195141004\" class=\"forum-content-3 forum-entity-placement\">\t\t<div class=\"ad-wrapper\" style=\"width:100%;min-height:250px;text-align:center\">\r\n\t\t\t<!-- In Article Blog -->\r\n\t\t\t<ins class=\"adsbygoogle\"\r\n\t\t\t\t style=\"display:block; text-align:center;\"\r\n\t\t\t\t data-ad-layout=\"in-article\"\r\n\t\t\t\t data-ad-format=\"fluid\"\r\n\t\t\t\t data-ad-client=\"ca-pub-3476569516614521\"\r\n\t\t\t\t data-ad-slot=\"9829044906\"><\/ins>\r\n\t\t\t<script>\r\n\t\t\t\t (adsbygoogle = window.adsbygoogle || []).push({});\r\n\t\t\t<\/script>\r\n\t\t<\/div><\/div>\n<h2>Test summary<\/h2>\n<p><em><i><b>Learn about SBMARK audio tests<\/b>: For scoring and analysis in our smartphone audio reviews, SBMARK engineers perform a series of objective tests and undertake more than 20 hours of perceptual assessment under controlled laboratory conditions.<br \/>(For more details on our reproduction protocol, click here; for more details on our registration protocol, click here.)<\/i><\/em><br \/><em>The following section collects the key elements of our exhaustive tests and analyzes performed in SBMARK laboratories.

However, the midrange is less consistent, which results in a slightly more subtle tonal balance overall.  The Samsung Z Flip4 device also performs well in dynamics, with a crisp and precise attack, good bass accuracy and decent punch, despite the lack of support for low-mid frequencies.<\/p>\n<p>The Flip4&#8217;s stereo speakers offer a good breadth of the stereo scene, but considering the phone&#8217;s fairly large size when unfolded, we expected even better.  Distance rendering is overall correct and depth perception is decent for common types of content.  However, localizability could be better, with individual instruments sometimes sounding fuzzy within the soundstage.  Maximum volume is decent and on a similar level to the more conventional Galaxy S22 Ultra.  The minimum volume, on the other hand, is a little too low, which means that some content, such as classical music, can be difficult to consume at this volume setting.  As with all of Samsung&#8217;s Galaxy series devices, audio artifacts are very well controlled, with only slight distortion and compression at maximum volume.  The device is also designed to reduce the risk of accidentally covering the speakers with your hands.<\/p>\n<p>Hear about the playback performance of the smartphone tested in this comparison with some of its competitors:<\/p>\n<div class=\"row\">\n<div class=\"col large-12\">\n<div class=\"container\">\n<div class=\"row device-block-container\" id=\"\">\n<div class=\"col large-4 small-12\">\n<div class=\"col-inner\">\n<div class=\"box-shadow-2 device-block \" style=\"width: fit-content !important\">\n<div class=\"box box-text-bottom\">\n<div class=\"box-text\">\n<p>Samsung Galaxy S22 Ultra (Exynos)<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"row\">\n<div class=\"col large-12\">\n<p>\n                    <em>Recordings of smartphones that play some of our music at 60 LAeq in an anechoic environment from 2 microphones in AB configuration, at 30 cm<\/em>\n                <\/p>\n<\/p><\/div>\n<\/p><\/div>\n<p>Here&#8217;s how the Samsung Galaxy Z Flip4 fares in playback use cases compared to its competitors:<\/p>\n<div class=\"row\">\n<div class=\"col large-12\">\n<div class=\"echarts-item\">\n<p>Playback of use case scores<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<p><!-- PLAYBACK TIMBRE --><\/p>\n<div class=\"info-box\">\n<div>\n<div class=\"info-box-content\">\n<p>The Timbre score represents how well a phone reproduces sound across the audible tonal range and takes into account bass, midrange, treble, tonal balance and volume dependence.

These recordings are performed in our labs and in real-life conditions, using apps and predefined settings.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<p>Overall, the Z Flip4 is better for sound recording than for playback.  The recording tone is good, with an overall satisfactory low-mid range and a pleasant bass rendition.  However, a less present mid-high range contributes to a less clear sonority and a slightly recessed treble extension, making the treble sound a bit dull.<\/p>\n<p>Dynamic performance is good, with excellent signal-to-noise ratios when recording with the selfie camera and decent values \u200b\u200bfor all other use cases.  The envelope rendering is also correct in all use cases, but it lacks some precision.  The attack is decent but could be more precise.  The Samsung performs well for spatial attributes when recording, with excellent distance rendition and good stereo width when recording with the main camera.  However, the amplitude is reduced when recording in portrait orientation with the front camera and the recorder app is mono by default.<\/p>\n<p>The recording volume is mostly correct, but in real life scenarios the volume can drop considerably if there is a lot of background noise.  This is especially true for front camera recordings and when using the recorder app. <span style=\"letter-spacing: 0.35px;\">The Z Flip4 performed exceptionally well for maximum volume and is capable of handling loud recordings with only a little distortion. <\/span><\/p>\n<p>However, the usual moderate distortion and compression are evident in recordings of high volume content, and the Z Flip4 seems quite sensitive to microphone occlusions and finger noises, resulting in fluctuating cuts, filters and modulations.  Background rendering is very good, with excellent tonal balance, well-controlled artifacts and only some volume fluctuations.<\/p>\n<p>Here&#8217;s how the Samsung Galaxy Z Flip4 fares in recording use cases compared to its competitors:<\/p>\n<div class=\"row\">\n<div class=\"col large-12\">\n<div class=\"echarts-item\">\n<p>Record of use case scores<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<p><!-- RECORDING TIMBRE --><\/p>\n<div class=\"info-box\">\n<div>\n<div class=\"info-box-content\">\n<p>The Timbre score represents how well a phone captures sounds across the audible tonal range and takes into account bass, midrange, treble and tonal balance.
