2.1.14. High-pass filter

---

The high-pass filter parameter allows you to enable or disable a high-pass filter on the input signal. This can be used to remove low-frequency noise from the input signal.

The high-pass filter only prevents boosting of low frequencies, it does not prevent attenuation. This means that the high-pass filter can be used to remove low-frequency noise from the input signal without negatively impacting loudness compensation.

True gain is reflected in the contour visualization.
