C55x CSL Audio Pre-Processing

This application report describes the audio pre-processing for speech recognition framework provided in the C55x CSL. This demo illustrates the integration of Beamforming (BF), Adaptive Spectrum Noise Reduction (ASNR), Multiple Source Selection (MSS) and Dynamic Range Compression (DRC) components and provides a framework for application development.
