An Audio Processing System Based on DRC and FFT Integration

This paper aims to develop an audio processing system that integrates Dynamic Range Control (DRC) and Fast Fourier Transform (FFT) technology, aiming to provide a clearer and more natural auditory experience for hearing-impaired individuals; By precisely adjusting the amplitude and frequency of audio signals, this system can adapt to individual hearing characteristics and diverse auditory environments. It combines two technologies to achieve two-dimensional audio adjustment. Compared with traditional hearing aids, this system demonstrates higher flexibility and adaptability. It can dynamically optimize audio signals based on real-time audio environments and user hearing test results, and is expected to improve communication skills and quality of life for hearing impaired individuals.
