Want your screen recording to capture the sound your phone is playing? This tutorial shows you how.
To record internal audio while screen recording on Android — that is, the sound the phone itself plays, such as audio from a video or game sound effects — you need two things:
If your phone runs a version below Android 10, the system doesn't support internal audio recording, unfortunately. You can only record speaker sound through the microphone, which sounds worse and picks up ambient noise.
Kuailuping is a free Android screen recorder that supports internal audio recording, and it's very easy to use:
Download the Kuailuping APK from the download page and install it. Kuailuping supports Android 10.0 and above, and the installer is about 6.3MB.
Open Kuailuping and find the "Audio source" option on the recording settings screen. Choose "Internal audio". You can also choose "Microphone" (to record external sound) or "Silent" (video only, no sound) as needed.
On the same screen you can set the recording resolution (up to 1080P), frame rate (up to 30fps), and bitrate — choose whatever you need.
Tap the "Start recording" button. The system will show a screen-recording permission prompt; tap "Start now". A "Recording" notification appears in the notification shade, where you can pause or stop the recording.
While recording, the sound your phone plays is captured directly into the video, with no ambient noise — much better audio than pointing a microphone at the speaker.
Tap "Stop" in the notification shade to end the recording; the video is saved automatically to your phone's gallery. You can also open Kuailuping's "Video library" to view, share, or delete recordings. Videos are saved by default to the Movies/ScreenRecorder/ folder in internal storage.
Kuailuping supports internal audio recording on Android 10+, free with no watermark, and saves videos locally.
If the video still has no sound after following the steps above, it's usually one of these:
Some video apps, banking apps, and DRM-protected content actively block the system from capturing their audio output. This is an app-level restriction that no screen recorder can bypass. Try recording another app's sound to see if this is the cause.
Check the Android version under "Settings → About phone". On Android 9 or below, the system doesn't support internal audio recording, so you can only use the microphone.
On some phones, internal audio recording is silent when the phone is in silent mode or the media volume is zero. Try turning the media volume up before recording.
If the phone is connected to a Bluetooth headset or speaker, audio may be routed to the Bluetooth device. Try disconnecting Bluetooth before recording.
In short:
Choose based on what you're recording. Kuailuping switches between them with one tap in settings — no reinstall needed.
Recording internal audio requires Android 10.0 or above. Android 9 and below are limited by system permissions and can only capture external sound through the microphone; they cannot directly record the phone's own audio output.
Some apps (such as certain video platforms and banking apps) block the system from capturing their audio output — this is the app's own copyright protection or security restriction, which no screen recorder can bypass. Try microphone mode, or record an app that allows audio capture.
Most Android phones only allow one audio source at a time: internal audio or the microphone. Kuailuping lets you switch the audio source in settings — internal audio, microphone, or silent recording.
Videos recorded with Kuailuping are saved to your phone's local gallery and can also be viewed and managed in Kuailuping's video library. The default storage path is the Movies/ScreenRecorder folder in internal storage.
