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 widely used in music production, broadcasting, and telecommunications to ensure clear and balanced sound. In modern technology, audio processing is often performed using digital signal processing (DSP) techniques. These methods allow for real-time adjustments and can be found in software applications, such as digital audio workstations (DAWs), as well as hardware devices like mixers and effects processors. This versatility makes audio processing essential in various fields, including film, gaming, and virtual reality.
