Differences between soft knee and hard knee in Dynamic Range Compression (DRC)?
I want to know more about where it is advantageous to use a soft knee and where and why a hard knee is preferred. Also I would like to get my hands on some good resources which talk about implementation of soft knee in DRC

How to derive equation for second order interpolation of soft knee cutoff in a compressor?
I am reading Audio effects: theory, implementation and application by Joshua D. Reiss and Andrew McPherson.
They explain that, in the simplest case with just a hard cutoff threshold, you have a piecewise linear equation
$$y_G = \begin{cases}
x_G &…

RMS typical length for audio dynamic compressor
I know what does it mean Root Mean Square. But I can’t find any information what is typical portion (length) of audio signal for RMS envelope detector in dynamic audio compressor.
Of course I know it depends on compressor design, there are many…

Compute dynamic range in a linear quantization system
I know the dynamic range is the ratio between the maximum amplitude and the minimum amplitude of a signal, calculating the dynamic range in dB I get a difference of logarithms:
But why the dynamic range of a N-bit digital system with linear…
