Limitations • Spotify patch • Downloads • Credits

This app uses libjamesdsp which is written by James Fung (@james34602).

This app has several limitations that may be deal-breaking to some people; please read this whole document before using the app.

Limitations

• Apps blocking internal audio capture remain unprocessed (e.g., Spotify, Google Chrome)
• Apps using some types of HW-accelerated playback currently cause the audio processing service to stop itself (e.g., some Unity games)
• Cannot coexist with (some) other audio effect apps (e.g., Wavelet and other apps that make use of the DynamicsProcessing Android API)
• Increased audio latency

Apps confirmed working:

• YouTube
• YouTube Music
• Amazon Music
• Deezer
• Poweramp
• Substreamer
• Twitch
• Spotify ReVanced (Patch required)
• Apple Music
• ...

Unsupported apps include:

• Spotify (patch for Spotify exists)
• Google Chrome
• SoundCloud
• ...

Tested on:

• Samsung Galaxy S20+ (Android 12; OneUI 4.0)
• Stock AOSP emulator (Android 10-13)
• Google Pixel 6 Pro (Android 13)

Spotify support patch

You can only use Spotify with this application if you patch the Spotify app. The setup is very easy:

1. Download and install the ReVanced manager APK
2. Install the unpatched Spotify app

NOTE: Tested with Spotify version 8.7.48.1062 and 8.7.68.568

3. Open ReVanced Manager, select Spotify and enable the disable-capture-restriction patch.
4. Start the patching process and install the patched APK once it is done.
5. You can now use Spotify with RootlessJamesDSP.

Using Root

This app focuses on a rootless implementation, but it can be made to work with the magisk module too. See here for details.
