How to reduce an audio signal to proper input level ...
https://electronics.stackexchange.com/questions/64606/how-to-reduce-an-audio-signal-to-proper-input-level
That would be useful when you have a normal line level audio signal as your circuit is intended to work with. Another option, is to use a potentiometer in place of R1 and R2. A potentiometer (pot) is a single resistor, which in this case is the combination of R1 and R2. But, it has a third terminal, which is a wiper that can be positioned ...
GitHub - AP-Atul/Audio-Denoising: Noise removal/ …
https://github.com/AP-Atul/Audio-Denoising
Audio De-noising. A simple yet very powerful noise remover and reducer built in python. The noise removed by using Wavelet Transform. Wavelets has been very powerful tool to decompose the audio signal into parts and apply thresholds to eliminate unwanted signal like noise. The thresholding method is the most important in the process of Audio De nosing.

Reducing Signal Noise in Practice | Precision Digital
https://www.predig.com/whitepaper/reducing-signal-noise-practice
Reducing Signal Noise in Practice. Ground Loops & Non-Isolated Commons. Signal noise in an industrial environment has the ability to cause havoc with process control systems. This electrical noise can inject itself onto analog or digital signals and fool control equipment into thinking the process variable is different from what it actually is.
ESOTERIC SOUND'S SURFACE NOISE REDUCER
http://www.esotericsound.com/rvw5_snr.htm
The signal path is more complex, so just a little less pure, but the penalty is slight for such a significant lessening of the annoyance factor by the Surface Noise Reducer. Note again that its not called the Surface Noise Eliminator.
