Does screen recording record audio? Yes, most screen recorders capture sound, but whether your finished clip actually plays audio depends on the device you use and the settings you chose before you hit record. Screen recording is fully capable of recording audio; it simply does not always do it automatically, and when a recording comes out silent the cause is nearly always a setting rather than a broken feature. On an iPhone the app or system sound records by default while your voice does not. On a Mac the built-in tool happily records your microphone but never captures internal audio on its own. Same question, different answer on every platform, because the device decides what happens the moment you press record.
The one idea that clears up almost all of the confusion is this: system audio and microphone audio are two separate streams, and every operating system treats them differently. System audio is the sound coming out of what you are recording, such as a video playing in a tab, a game, or another person on a call. Microphone audio is your own voice narrating over the top. Some tools capture both, some capture one and silently ignore the other, and a few refuse to record system audio at all for privacy reasons. Once you know which stream you actually need, the settings stop being mysterious. This guide covers what each platform records by default, why a recording ends up silent, and how to guarantee your next one is clear. If capturing your screen is new to you, our guide on how to record your screen is a good place to start.
System Audio vs Microphone Audio: The Key Difference
Every screen recording can, in theory, contain two audio tracks, and understanding the difference between them solves most sound problems before they start. The first is system audio, sometimes called internal audio or device audio. This is everything the machine itself is playing: the soundtrack of a video, the beep of an alert, a voice on a video call, the effects in a game. The second is microphone audio, which is whatever your mic picks up from the room, usually you, talking through what is on screen.
These two streams are captured by different parts of the operating system, which is why they behave independently: you can end up with a recording that has your voice but no app sound, or the reverse, depending on which toggles were on. The split also explains a privacy rule that trips people up constantly, because operating systems are cautious about letting any app silently record what another app is playing, which could expose private calls or protected media. That caution is why microphone capture is usually off until you turn it on, and why macOS blocks internal-audio capture entirely with its built-in tools. When you only need the sound and not the picture, our extract audio and video to audio tools pull a clean track out of any recording you already have.
Does Screen Recording Record Audio on iPhone and iPad?
On an iPhone or iPad, screen recording records audio by default, but only one kind of it. When you start a recording from Control Center with a normal tap, iOS captures the internal system audio, meaning the sound from the app, game, or video on screen, automatically, as long as your phone is not muted. What it does not capture by default is your microphone. Apple keeps the mic switched off at the start of every recording as a privacy measure, so if you tap record and start talking, your commentary will not be in the video.
Turning the microphone on takes one extra step. Instead of a quick tap on the Screen Recording control, press and hold it, then tap the Microphone button at the bottom so it turns red before you start recording, and iOS mixes your voice together with the system audio. The setting often resets between sessions, so check it before an important take. If your recording is silent even with the mic on, the usual culprits are the physical Ring and Silent switch set to silent, a Focus mode muting sounds, or the volume turned all the way down. Apple documents the Control Center recorder in its own iPhone support pages, and our companion guide on how to screen record on iPhone and Android walks through the whole flow with sound.
Does Screen Recording Record Audio on Android?
Android is more flexible than iPhone and more variable, because the options depend on your phone maker and Android version. The built-in recorder on most modern phones, including Google Pixel and Samsung Galaxy models, asks you to choose an audio source, and that choice decides everything. Device audio captures the internal system sound, Microphone records only your voice, Device audio and microphone records both together, and None produces a silent video on purpose.
Because that menu exists, an Android recording with no sound is almost always the result of None being selected, or of the recorder never being granted microphone permission. If your voice is missing, open Settings, then Apps, find your screen recorder, open Permissions, and make sure Microphone is allowed, since system updates occasionally reset it. If the app sound is missing, reopen the recorder settings and switch the audio source to Device audio, or to Device audio and microphone if you are also narrating. Google's Android help pages cover the stock recorder, though Samsung and Pixel phones word the options slightly differently.
Does Screen Recording Capture Audio on Windows and Mac?
On Windows, the built-in Xbox Game Bar records audio out of the box. Press the Windows key plus G to open it, open the Capture widget, and press record; by default it captures the system audio of the active app. Despite the name, it works for any application, not just games. The microphone is the optional part: click the microphone icon in the Capture widget, or press the Windows key plus Alt plus M, to include your voice. If the mic still does not record, check that Game Bar has permission under Settings, then Privacy and security, then Microphone, and that the audio-to-record setting is All rather than Game only. Microsoft documents the tool on its Xbox Game Bar support pages, and our guide on how to record your screen covers the full walkthrough.
The Mac is where people are caught out most often, so it is worth being precise. Pressing Shift plus Command plus 5 opens the built-in screen recording toolbar, and under Options you can select your microphone, so recording your own narration works perfectly. What the native tool cannot do is capture your Mac's internal or system audio. Record a video playing in Safari, or a call, using only the built-in recorder or QuickTime, and the picture is there but the app sound is missing. This is not a bug; Apple deliberately prevents apps from tapping another app's audio stream for privacy. The standard workaround is to install a virtual audio device such as BlackHole, route the system sound through it, and select it as the input. Our dedicated guide on how to screen record on Mac covers that setup step by step.
Why Your Screen Recording Has No Sound (and How to Fix It)
When a screen recording plays back silent, the cause is almost always one of a handful of settings, and they are quick to check. First, confirm the microphone was actually enabled, since a mic that was never switched on is the single most common reason a narration is missing. On iPhone that means turning the mic red before recording, on Windows toggling it in Game Bar, and on Android choosing an audio source that includes the microphone.
Second, check that the device itself is not muted. A silenced iPhone Ring and Silent switch, an active Focus or Do Not Disturb mode, or a system volume dragged to zero will all strip sound from a recording. Third, verify microphone permissions, because operating-system updates sometimes revoke them without warning. Fourth, look at your audio output, since connected Bluetooth headphones or speakers can quietly redirect sound away from the recorder, so disconnecting them before you record often fixes a silent file.
Fifth, remember the Mac rule from earlier: the built-in tools never capture internal audio without a virtual audio device, so a Mac recording with your voice but no app sound is working exactly as designed. And sixth, some content simply cannot be recorded, because streaming apps like Netflix and many music services apply digital rights management that mutes their audio during any screen capture, and no recorder can override that. To sanity-check your microphone and setup before an important take, run the free screen recording checker first.
Getting Clean, Captioned Audio Every Time
Native tools are fine for a quick capture, but they leave you managing mute switches, permissions, and virtual audio drivers every time, with no safety net when the sound still comes out wrong. Zidi removes most of that friction: it records your screen, camera, and microphone together in the browser or through its Chrome extension, with clear device pickers so you can see exactly which mic is live before you start. Because you choose your inputs up front, the classic silent recording simply does not happen.
The bigger advantage shows up after you stop. Zidi automatically generates AI subtitles and captions in more than 90 languages on every plan, including the free one, so even a viewer watching on mute can follow every word. Captions turn an audio-dependent video into one that works with the sound off, often the difference between a recording that gets watched and one that gets skipped. Export those captions with the subtitle and SRT generator, or pull the spoken track out of a finished video with the extract audio and video to audio tools when you need the sound as a standalone file.
Zidi also cleans up the audio you did capture. Its automatic filler-word and silence removal, available on all plans, strips out the ums, the long pauses, and the dead air, so a rambling take becomes a tight one without manual editing, and you can see how many filler words crept in with the free filler-word counter. To be clear about the boundary, the audio still comes from your microphone and the tab or app you share; Zidi does not manufacture sound that was never recorded. But between clear input selection, captions in more than 90 languages, and automatic cleanup, it turns the fragile business of recording sound into something that just works.

Frequently Asked Questions
Does screen recording record audio on iPhone? Yes, but only the system audio by default, so app and video sound records automatically unless the phone is muted. Your microphone is off by default for privacy, so to add your own voice you press and hold the Screen Recording button in Control Center and tap the Microphone icon until it turns red before you start.
Why is there no sound in my screen recording? The most common reasons are that the microphone was never enabled, the device was muted by a silent switch or Focus mode, the recorder lacks microphone permission, or the volume was at zero. On a Mac specifically, the built-in tool never records internal system audio without a virtual audio device, and streaming apps with DRM protection mute their own sound during any capture.
How do I screen record with sound? Pick the audio you need before recording. On iPhone, long-press the record button and enable the microphone. On Android, choose Device audio, Microphone, or both. On Windows, toggle the mic in Xbox Game Bar with the Windows key plus Alt plus M. On Mac, select your mic under Options in the Shift plus Command plus 5 toolbar, and add a virtual audio device if you also need internal sound. A dedicated tool like Zidi lets you pick every input up front so nothing is missed.
Why can't my Mac record internal or system audio? Apple deliberately prevents apps from capturing another app's audio stream for privacy reasons, so the built-in Shift plus Command plus 5 recorder and QuickTime can record your microphone but not the sound playing on your Mac. To capture internal audio, install a virtual audio device such as BlackHole and route the system sound through it.
Does screen recording capture the other person's voice on a video call? It depends on the platform. On iPhone and Windows, system audio is included by default, so the other person's voice is usually captured along with your own if the microphone is on. On a Mac with only the built-in tools, their voice comes through the system audio channel that macOS will not record, so you would need a virtual audio device to capture both sides of the call.
Can I add sound or captions to a recording that already has no audio? You cannot recover audio that was never captured, but you can make a silent or hard-to-hear recording usable. Captions are the most reliable fix, and a tool like Zidi adds AI subtitles in more than 90 languages so the video is understandable on mute, while its filler-word and silence removal tightens up the audio you did record.
The Bottom Line
So, does screen recording record audio? Yes, every major platform can capture sound, but each one handles it differently, and the difference between a great recording and a silent one is almost always a single setting. Remember the core distinction: system audio is what your device plays, microphone audio is your voice, and they are controlled separately. iPhone records system sound by default and needs the mic turned on by hand. Android lets you pick the source outright. Windows Game Bar captures system audio and makes the mic optional. And the Mac records your mic but never internal audio without a virtual driver, the caveat that catches most people out.
Once you know what your device does by default, silent recordings mostly disappear, and the fixes above cover the rest. If you would rather not think about mute switches and permissions at all, a dedicated platform like Zidi lets you confirm every input before you record, adds AI captions in more than 90 languages so your message lands even on mute, and cleans up filler words automatically.
