What Is a Compressor in Music Production?
A compressor is one of the most essential tools in music production and mixing. In simple terms, it controls the dynamic range of a sound — meaning the difference between the loudest and softest parts. By reducing peaks and boosting quiet parts, compressors make a track sound more balanced, polished, and professional.
