Active-filtering circuit for audio DACs
https://www.ti.com/lit/pdf/sbaa322
This circuit shows the implementation of a second-order active-filter for audio digital-to-analog converter (DAC) applications. In applications such as automotive head units, home theater soundbars, and AV receivers, it is critical to minimum undesirable noise in the audible range, approximately 20Hz to 22kHz. For this reason, many delta-sigma type audio DACs implement …

As above is the schematic diagram. This circuit includes the low filter circuit through R1 and C2, the frequency cut off at 1,600 Hz. In the FSK system, logic “0” instead of with the frequency of 1,200 Hz. Thus, this filter will reduce the roughness of the edge signal as two waveforms (A) and (B). watch on the oscilloscope.
Audio Filters: Understanding the filters - Part 5
https://www.engineersgarage.com/audio-filters-basics-of-audio-filters-5-8/
Audio filters are the electronic circuits designed to amplify or attenuate a certain range of frequency components. They serve as a unique type of amplifier or a passive circuit with frequency-dependent outputs. Essentially, they help eliminate any unwanted noise from an audio signal, improving the tone of the output.

Low-Pass Filters. As their name suggests, low-pass filters block high frequencies while allowing low frequencies through the circuit. Low-Pass Filter: For more information on calculating component specification values, see here. High-Pass Filters. High-pass filters perform the opposite function, permitting high frequencies and blocking low ones.
