AudioFilterBuffer

Platform-specific audio filter buffer implementation for real-time audio processing.

This abstract type provides a unified interface for accessing audio sample data across different platforms:

• C++ targets: Uses native pointer access for optimal performance
• JavaScript/Web targets: Uses Float32Array for Web Audio API compatibility

The buffer contains interleaved audio samples as 32-bit floating point values, typically in the range [-1.0, 1.0]. Audio filters use these buffers to process audio data in real-time, applying effects like low-pass, high-pass, or custom DSP algorithms.
