Accessing VLC Audio Effects/Filters – Equalizer, Compressor and Others

Audio effects and filters are useful in VLC Media Player if you use it as your standalone music player or as a movie player. The equalizer, compressor and other advanced effects are put in place to help your audio give that crunchy sound that’s music to your ears. You can use VLC’s equalizer to correct the currently playing sound and music across various decibel (dB). There’s also a 2 pass option. You may also find the use of the built-in compressor to lessen the dynamic range between loudest and quietest audio. Furthermore, there’s also a spatializer for surround sound settings.

If you would like to dig further into the audio filters, there are more options in the advanced settings. You will find filter settings related to audiobar graph, compressor, delay, equalizer, gain, headphone effect, mono, parametric equalizer, remap, scaletempo, spatializer, stereo enhancer and volume normalizer. These advanced settings make it seem that VLC is a total rockstar in audio settings. But a normal user won’t be using most of them. Only a sound engineer will know how to make use of all these options. So, this post is to help you find VLC’s built-in audio effects.

The Most Used Audio Effects and Filters

It consists of Equalizer, Compressor, and Spatializer. To access it, go to Tools > Effects and Filters or press the shortcut key CTRL + E.

  • Compressor: Enable and use it like the equalizer.
  • Spatializer: It’s the same, enable and drag the sliders to fit your taste.

One thought to “Accessing VLC Audio Effects/Filters – Equalizer, Compressor and Others”

  1. I never understood what the Resampler function in VLC does, and searching the net only yields results about people having problems with resamplers making the audio quality bad, which only serves to make me more interested in finding out what it actually does, and if I need it. It’s on ‘Auto’ for me right now.

    So, what does the resamplers do and/or when is a resampler needed/feasible?
