Dynamic Equalizer

Dynamic equalizer is essentially a type of a conventional parametric equalizer. It is “dynamic” because the otherwise static gain of the filter is replaced by a dynamic control loop. Parameters such as frequency and quality (Q) remain the same. Depending on the design...

Shelving Equalizer

Frequency range   Equalizers are in most cases described to the reference of what is called a “flat response curve”. This means that system or a piece of equipment responds equally to all frequencies within the specific range. This range is usually set to 20 Hz...

Band-Pass Filter

A bandpass filter, also known as BPF, is a type of filter circuit that unlike low pass and high pass filters passes frequencies within a certain range and attenuates frequencies outside that range. Bandpass is an adjective that describes a type of filter or filtering...

Comb Filter

Summing two signals   Comb filtering occurs when two audio signals are summed together with the difference in very small delay between them. This effect tends to happen a lot when two or more microphones are picking up the same audio signal. They then summit...

Low Pass Filter

What is a Low Pass Filter   A low pass filter, known as LPF, is essentially a filter that reduces or eliminates the frequencies above the cutoff frequency. It passes low-frequency signals and blocks or impedes, high-frequency signals. In audio applications, this...

High Pass Filter

What is a high pass filter?   In order to put it simply, we could say that the high pass filter is just a filter (low-cut) that attenuates frequencies below the certain cutoff frequency and allows the frequencies above to pass. There are many kinds of high pass...
