- Created a new SIMD interface header and source files for audio processing functions. - Implemented functions for filling buffers, mixing audio, applying gain, calculating RMS and peak values, normalizing audio, converting stereo to mono, limiting audio, fading audio, and a simple equalizer. - Added SSE-specific implementations for the audio processing functions to leverage SIMD for performance improvements. - Updated CMakeLists.txt files to include new libraries and link dependencies for the SIMD interface and SSE implementations. - Introduced a static test helper library for unit testing with Google Test framework.
