Audio Program for Generating Various Special Effects including Echoes and Hand Claps

MATLAB-based audio program developed to produce special sound effects such as echoes and hand claps through advanced audio processing algorithms.

Generation of Echo-Added Audio Files from Sound Signals

The system enables the generation of echo-added audio files from sound signals, facilitates echo cancellation to recover the original signal, and additionally estimates the distance of reflective objects based on acoustic characteristics.

Designing an M-Order Adaptive Echo Canceller

Design an M-order adaptive echo canceller using u(n) as system input and d(n) as desired system response, where d(n) contains echoes of u(n). With signals sampled at 8kHz, the echo canceller must eliminate echoes within 16ms. Implementation requires careful selection of adaptive filtering algorithms and proper parameter configuration to handle the specified echo path delay.
