Audio Noise removal in java - Stack Overflow
https://stackoverflow.com/questions/42314122/audio-noise-removal-in-java
Need an algorithm (or a set of good ones to compare for various input data) that will reduce the noise level of a voice audio signal without distorting the signal appreciably using Java. Input is an audio signal that includes a voice along with some background noises. The noise varies over the course of the recording.
