//! Module for digital signal processing (DSP) operations.
//!
//! Contains utilities for audio buffer manipulation, optimized for
//! stereo operation and clipping safety.
//!
//! # Features
//! - **Gain and Ramp**: Linear gain application and SIMD ramps for smooth transitions.
//! - **Clipping Detection**: Detection of peaks above 0dBFS integrated into gain application.
//! - **Stereo Processing**: Kernels that operate simultaneously on L/R channels for better cache locality.
//! - **Energy Computation**: RMS/Peak energy calculation for signal telemetry.
//!
//! Contains implementations of optimized audio algorithms, including
//! energy calculations, correlations, and filters.
