2. Performance on Low-End Devices

Because Sonic.ribs uses 2D sprites over 3D backgrounds, the Android port runs at 60 FPS on devices as modest as the Samsung Galaxy A12. The developer added a "Low-Rib Mode" that reduces the visual complexity of the flesh textures for older GPUs.

3. Porting Objectives

  1. Functional Parity: All original audio transformation modes (pitch shift ±2 octaves, time stretch 0.5x–2.0x) must work.
  2. Latency: End-to-end latency ≤ 15 ms on flagship devices (2019+), ≤ 30 ms on mid-range.
  3. Resource Usage: CPU usage < 10% at 48 kHz stereo, RAM footprint < 8 MB.
  4. API Style: Provide both low-level C API and high-level Kotlin coroutine interface.
  5. Compatibility: Support Android 6.0 (API 23) to Android 14.

Physical Appearance: He is taller than the standard Sonic, has purple fur, purple buckles on his shoes, and notably lacks a standard blue color. His most defining feature is his exposed ribcage, and he is described as smelling of decay.
