An audio filter circuit is a broadband filter and is also called a wide bandpass filter because its bandwidth is restricted to the audio frequency. Audio filter circuit can be formed by simple cascading high pass filter circuit and low pass filter circuit and is generally the choice for simplicity of design and performance through such a circuit can be realized by a number of the …

This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and a high pass filter in a cascade configuration. Both filters are second-order filters with a 24 dB/octave fiter capability.

Re: De-pop circuit for speaker when powering on. « Reply #8 on: August 02, 2014, 02:19:53 pm ». Hi, You could try using a n-channel mosfet. Disconnect the speaker lead from gnd. Connect the speaker lead to the drain of the mosfet. Connect the source of the mosfet to gnd. Connect a capacitor (10 uF) between gate and gnd.
What really causes switch pop – Mr. Black

Its just the nature of the beast. As those contacts bounce around and settle into place, they generate a small amount of current and dump it wherever they can, whenever they can. In this case, into our input and output coupling capacitors causing "switch pop." And there it is. Easy-peezey, lemon-breezey, cheese.
