Importance of Precision on Performance for Digital Audio Filters Digital audio systems are unlike conventional analog systems in which signals can be any value between a minimum to maximum and occur continuously in time.
How digital filters affect analog audio signal levels
https://www.ti.com/lit/an/slyt375/slyt375.pdf
Digital audio processing provides a great amount of flexi-bility to system designers. Multiple filter structures can be cascaded to form equalization (EQ), low-pass, high-pass, shelf, and many other filter combinations with relatively low power consumption and little PCB space. Infinite-impulse-response (IIR) filters can be used to easily simu-

As a result, good digital filter performance is important to audio system design. Digital filters differ from conventional analog filters by their use of finite precision to represent signals and coefficients and finite precision arithmetic to compute the filter response. The precision that is used determines the digital filter's response accuracy and the filter signal to …

The word 'digital' as applied to audio means discrete both in time and amplitude. Digital filters, then, are inher ently nonlinear devices. A DSP (Digital Signal Processing) engineer must recognize and resolve aberrations from lin ear behaviour. n~n::~:or:~Jr-c Coefficient quantization, of itself, does not induce non linear behaviour.
Listening Comparison Of Digital Audio Filters
http://www.jeffchan.com/audio/filter-comparison.html
A filter that needs to roll off a 176.4 kHz signal will be much gentler to the original signal than one that must do most of the work between 20 and 22.05 kHz. The gentler filter has less effect on the desired signal output, and this may be a major reason high sampling rates such as 96 kHz and 192 kHz, or SACDs high DSD bitrate sound better.
INTRODUCTION TO DIGITAL FILTERS

Advantages of using digital filters The following list gives some of the main advantages of digital over analog filters. 1. A digital filter is programmable, i.e. its operation is determined by a program stored in the processor's memory. This means the digital filter can easily be changed without affecting the circuitry (hardware).
