Today, iFi Audio officially released a new series of noise reduction products, designed to eliminate power-related noise issues commonly encountered in audio systems. Called SilentPower, the series ranges from inline noise/ground loop removers like …
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 …
Audio Filters: Understanding the filters - Part 5

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.

High-pass filters are also frequently employed to clean up audio signals from non-bass instruments: unless a channel is intended to carry very low frequencies (such as the bass guitar or piano), it is unlikely that the very low frequencies contain useful sound, so a high-pass filter between the signal source (like a microphone) and the board can enable a higher sound quality.
