See How Audio Filters Work - Compressor, Notch, Shelf, Limiter and More

This course explains how audio filters and dynamic-processing tools change audio signals and when to use them to improve sound quality. It demonstrates signal measurement, loudness, room-acoustic correction, compression, dithering, safe recording levels, active noise cancellation, limiting, and soft clipping.
