XAudioCapture

Record any audio stream you want.

Since Android 10, the system introduced the AudioPlaybackCapture API for capturing internal audio playback. It also implemented policies that allow applications to decide whether to permit their audio output to be recorded by other applications or the system.

This Xposed module let you to capture any audio stream you desire, bypassing these restrictions.

Features

• Reasonable UI
• Hooks both ApplicationInfo.privateFlags and AudioAttributes.Builder#setAllowedCapturePolicy(int).
• May Works with multi-user (not tested yet)

How it works?

This module inject hooks to the android system package, and add PRIVATE_FLAG_ALLOW_AUDIO_PLAYBACK_CAPTURE into Application’s privateFlags.

Usage

1. Enable XAudioCapture (this module) in your LSPosed framework setting
2. Hook the android system package in scope setting
3. Launch XAudioCapture UI, select the app you want to record
4. kill and restart the victim app
5. Enjoy!

Notes

1. Only tested on LSPosed.
2. If recording still didn’t work, also hook the target application in scope setting. This will hook AudioAttributes.Builder#setAllowedCapturePolicy(int) while the target application calls it.
3. For users with Work profile, install this all in both your Main profile and Work profile. Attach to android package in your Main profile, and tick the apps you want to record in the according profile.

Special Thanks
