Google Resonance looks really interesting. It's similar to Steam Audio, but AFAIK Steam Audio's core is not open source and Resonance should be more mobile-friendly due to optimization/compromises in head-related transfer function computation. Unfortunately both Steam Audio and Resonance focus on just 3D spatialization and skip on basic functionality like pitch shifting.
