How to record your Android screen with internal audio

You're recording gameplay, an app review or an online class, and the finished video only has the sound of your room: a fan, a pressure cooker, a neighbour's TV. Familiar? The good news is that since Android 10, you can record your screen with internal audio on Android directly, with no microphone held up to the speaker. This guide shows how it works, how to set it up, and why a few apps still stay silent.

Internal audio vs microphone

Internal audio (also called system audio or device audio) is whatever the phone itself is playing: videos, games, music, app sounds. It is captured digitally, straight from the phone, so there is no room echo and no background noise in that track.

The microphone records the world around the phone, which mostly means your voice. Most tutorials need both at once: the app's sound so viewers hear what happens, and your voice so they know why it happens. A game commentary is the same idea: game sound from inside, your reactions from the mic.

Before Android 10, the only way to get app sound into a recording was to play it loudly through the speaker and let the mic pick it up. That gave thin, echoey audio mixed with every noise in the room. Internal capture fixes that.

What you need before you start

• Android 10 or newer. You can usually check under Settings → About phone → Android version. On older versions, recorders can only use the microphone.
• A recorder that supports system audio. Cinematic Recorder can record the microphone and internal audio together in the same video.
• Microphone permission. Android asks once. Even if you only want internal audio, many phones still need this permission for the audio side of recording.
• Enough free storage. Audio adds a little to file size, and long recordings add up. Our screen recording storage tips explain how to keep files manageable.

How to record your screen with internal audio, step by step

1. Open Cinematic Recorder and go to Start recording.
2. Turn on System audio. Keep the Mic on if you want your voice too. Say a few words and watch the live level meter move, so you know the mic is actually working.
3. Choose your quality and frame rate. Up to 60fps is available with Premium (the free plan records up to 720p at 30fps), which helps for games and fast scrolling.
4. Tap record. Android shows its own screen-sharing prompt; tap Start now (the wording varies a little by phone brand).
5. Use the countdown to switch to the app you want to record. Start playing the video or game.
6. Pause, resume or stop from the floating controls, which stay available over any app. The finished video lands in your projects, ready for the editor.

Why are some apps silent?

Android lets every app decide whether its sound may be captured by other apps. Most apps allow it, but some do not, and the recorder cannot override that choice.

• Streaming apps: some movie and music services block capture for copyright reasons. You will often get silent audio, and sometimes a black picture too.
• Phone and video calls: call audio is never capturable on Android, for privacy and security. This is true for regular calls and for calls inside messaging apps.
• Some games: a few games opt out of audio capture, or use an audio mode that cannot be recorded.

That isn't a bug in the recorder; Android itself is blocking it. If an app also blocks the picture, see why some apps block screen recording.

Balancing your voice and the app's sound

Recording both tracks is only half the job. If the game is too loud, nobody hears your explanation; if it is too quiet, the demo feels flat. A few habits help a lot:

• Turn on Do Not Disturb before recording so notification pings stay out of the video (and private messages stay off the screen).
• Keep media volume around the middle. Internal audio follows the phone's media volume on most devices, so a full-volume game will drown your voice.
• Use a headset mic. A wired or Bluetooth headset mic usually sounds cleaner and closer than the phone's own mic, and it doesn't pick up the speaker.
• Mind the room. Don't sit right in front of a fan or AC unit. Soft furnishings like curtains and a bed reduce echo.
• Speak a little slower than normal. It sounds clearer over game music and is easier to caption later.

Common problems and quick fixes

The video has my voice but no app sound

Check that System audio was on, and that the app allows capture (use the YouTube test above). Some phones also mute internal audio when media volume is at zero. The full checklist is in how to fix a recording with no sound.

There is an echo

Echo usually means the mic is hearing the speaker while internal audio records the same sound digitally. Use headphones, or lower the speaker volume while you talk.

The sound drifts away from the picture

This can happen on long recordings when the phone is hot or short on storage. Close heavy background apps and keep some storage free.

Frequently asked questions

Does internal audio recording need root?

No. On Android 10 and later, apps can capture internal audio without root, as long as the app being recorded allows it.

Why is there no sound from a call?

Phone and video call audio is protected by Android and cannot be recorded by any screen recorder. Cinematic Recorder respects that limit.

Can I record internal audio without my voice?

Yes. Turn on System audio and turn the Mic off. This is handy for gameplay clips or recording an app's sounds without any room noise.

My phone is on Android 9. What can I do?

You can still record with the microphone. Keep the room quiet and play the sound through the speaker at a moderate volume; just expect it to include some room sound.

Once you have clean audio, the rest is easy. See all the recording features in Cinematic Recorder and start your next tutorial with sound you can be proud of.
