Noise is the unwanted electromagnetic energy that interferes with the ability of the receiver to detect the wanted signal. It may enter the receiver through the antenna along with the desired signal or it may be generated within the receiver.

$\begingroup$ All you need to do are : 1) prepare pairwise (X_i, y_i), where X_i is a vector representing your i-th audio signal, and y_i = 1 if this signal is noise, and 0 otherwise; 2) repeat step 1 for all samples you have; 3) say after step 2) you have K samples, you then make a big feature vector XX= [X_1;X_2;...;X_K], where its i-th row is your i-th feature X_i, and also a big …

At the end what has proven to be the best solution was onset detection based on either high frequency or energy content. Before it could work I had to use high-pass filter to cut out first 1 kHz, since it contained too much noise. Once I had noise-only area I could use its profile to reduce noise from rest of the sample.

of a weak carrier in noise and either sound an alarm or start some recording software. A simple threshold detector on the AGC line, or an audio filter followed by a tone detector, is one means to detect signals that are strong enough to trigger the circuitry, but for signals that are buried right down in the noise these techniques will not work.

Signal detection theory: Signals and noise. by Jeff Colombe . If you read a paper by a communications engineer, a cognitive psychologist, or an artificial intelligence researcher, chances are that you'll run into signal detection theory. Here's a quick primer on the subject. We begin with the idea that we are trying to measure a signal, maybe a ...
