Low-Pass Filter

The Low-Pass filter is used to attenuate frequencies above the cutoff frequency. Like all parametric filters, this one is usually used to correct various imperfections in the original audio.

Use the Play buttons to listen to and compare the sound before and after applying Low-Pass filter:

How to Apply

All effects and filters are applied in the same way in AVS Audio Editor. For detailed step-by-step instructions on how to apply effects to your audio files, click here.


Low-Pass Filter Settings

To apply the effect, use one of the available presets or configure the effect parameters manually.

Low-Pass Filter settings

The following Low-Pass filter settings are available for editing:

  • Cutoff Frequency - sets the frequency point at which the whole frequency range will be divided into 2 bands – pass-band and stop-band. All frequencies above the Cutoff Frequency will be attenuated in accordance with the attenuation curve. All frequencies below the Cutoff Frequency will not be affected by the filter.
  • Gain - sets the degree of amplification applied to the audio signal. Use it if you want to increase/decrease the resulting sound volume. The amplification will affect frequencies in both the pass- and stop-bands.
  • Limit Supression by - tick this option to limit the attenuation curve decay (lower shelf). The attenuation will stop at this point and the signal will not fall below this level.
  • Slope - sets the steepness of the frequency attenuation curve. Use it to control the transition between the affected and non-affected frequencies. Higher values correspond to a higher attenuation growth in the stop-band.
