Resource Overview
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.
Detailed Documentation
The system processes sound signals to generate audio files with customizable echo effects by adjusting echo parameters such as intensity and delay time. This is typically implemented using convolution operations with impulse responses representing the echo characteristics. For echo cancellation, the system employs inverse filtering or adaptive algorithms like LMS (Least Mean Squares) to suppress echoes and restore the original signal. Furthermore, the system incorporates time-delay estimation techniques, calculating the distance to reflective objects by analyzing the time difference between the direct sound and its reflections using cross-correlation methods or peak detection algorithms.
