CoSo is an AI-assisted sound creation app that allows users to create music in the moment. It is available for Android and free to use. CoSo is developed by Splice and falls under the Multimedia category with a subcategory of Music and Radio. The program name is Stacks.

CoSo simplifies the music creation process by serving up complementary sounds in real-time, allowing users to focus on their creative instincts. With CoSo, users can create a Stack by choosing a style and adding up to eight instrumental layers from across the Splice catalog. Each selection is unique and destined to work together.

The app is user-friendly, with a simple interface that allows users to swipe right to choose a new sound, swipe left to delete, tap a layer to mute it, and long-press to solo. Users can save their stack to TikTok, share it with friends, or export it to Ableton Live (coming soon). Additionally, users can locate their sounds in the Splice library to use them in their DAW.

Overall, CoSo is a great app for those looking to create music effortlessly and instinctively.
