Low Pass Filter
Attenuates frequencies higher than the cutoff frequency. The response of the filter can be dampened or made more aggressive (maybe causing resonance) by means of the quality factor. In this example, the cutoff frequency is 1000 Hz
Band Pass Filter
Attenuates frequencies higher or lower than the center frequency. The response of the filter can be dampened or made more aggressive (maybe causing resonance) by means of the quality factor. In this example, the center frequency is 1000 Hz
High Pass Filter
Attenuates frequencies lower than the cutoff frequency. The response of the filter can be dampened or made more aggressive (maybe causing resonance) by means of the quality factor. In this example, the cutoff frequency is 1000 Hz
Notch Filter
Eliminates center frequency and attenuates its surroundings. It can become sharper with a higher quality factor. In this example, the center frequency is 1000 Hz.
Peak Filter
Amplifies center frequency by a specific gain. The surrounding frequencies are also amplified. It can become sharper with a higher quality factor. In this example, the center frequency is 1000 Hz.
High Shelf Filter
Amplifies frequencies higher than the center frequency. In this example, the center frequency is 1000 Hz.
Low Shelf Filter
Amplifies frequencies lower than the center frequency. In this example, the center frequency is 1000 Hz.
