ADPCM Audio Signal Compression & Coding using MATLAB

Problem Definition

Problem Description: One of the major challenges faced in telecommunication networks is the efficient compression and coding of audio signals while maintaining a reasonable level of quality. Traditional methods of audio signal compression may result in loss of information or introduction of artifacts during the encoding and decoding process. Thus, there is a need for a more advanced and adaptive solution that can effectively compress audio signals without compromising on the quality of the output. By using ADPCM controlled Audio Signal Compression & Coding with MATLAB, we aim to address this issue by implementing an adaptive quantizer and predictor to efficiently code the input signal and reconstruct the original signal at the receiving end. This project will help in improving the efficiency and quality of audio signal compression in telecommunication networks, ultimately leading to better performance and user experience.
