Audio processing refers to the manipulation and analysis of sound signals to enhance or modify audio content. This can involve various techniques such as filtering, equalization, and compression, which help improve sound quality or create specific effects. Audio processing is commonly used in music production, broadcasting, and telecommunications. In digital audio, signals are converted into numerical data, allowing for precise editing and manipulation. Software tools, like Digital Audio Workstations (DAWs), enable users to apply audio processing techniques easily. This technology is essential for creating professional-sounding recordings and is widely used by musicians, sound engineers, and podcasters.
