Detailed Description

Circular buffer with interpolated reads for audio delay lines.

Provides a power-of-two circular buffer for strict real-time audio use: lock-free and allocation-free in the processing path. Storage is 32-byte aligned so callers can run SIMD kernels over data() spans; the class itself reads and writes scalars.

Features:

• 32-byte aligned storage
• Interpolation method selected at compile time (no per-sample dispatch)
• Safe pre-initialization state (all methods are no-ops before prepare())
• Multiple interpolation modes (Linear, Cubic, Hermite, Lagrange)

Threading: owner-managed. prepare() is setup-time; push/read/reset belong to the owning (audio) thread. Not internally thread-safe.

Dependencies: DspMath.h, Interpolation.h.
