Introduction

Imagine you are watching a movie. You cannot hear the artists' voices, even when you have maxed up the system’s volume. This gets quite nerve-wracking when you are watching a movie, you have been waiting for ages. Isn’t there any other way to max up the volume? If you are using the VLC media player, then the answer to your question is ‘YES’.

How to increase the VLC’s volume to the max?

In the latest version of the VLC media player (version 3.0.18), by default, the max volume control that can be set is 125%. This isn’t the max volume you can get when using the VLC media player. The max can be set up to 300%. To get maximum speaker output, first, make sure that the speaker volume is set to max.

You can follow these steps to set max the volume in the VLC media player:

Summary

  1. Open VLC media player.
  2. Press Ctrl+P.
  3. In show settings, check All.
  4. Click on Interface> Main Interfaces> Qt.
  5. Set Maximum Volume displayed to 300%.
  6. Click on Save.

Now, you can see the change in the Volume control once you restart the application. You are now able to go from 0% to 300%, which before was from 0% to 125%. This might just seem like a change in numbers, but actually, the max volume is now increased.

Testing and Results

Does this change the loudness of the output or is it just tweaking of numbers? Truly, this method changes the loudness of the output. To check whether things are working as desired, a test was performed using the Sound Meter app. The output volume of the device was set to max. A video clip was played on the same time frame and interval to validate the changes, before and after changing the preferences. The results are as follows:

It should be noted that a volume change of 10 dB makes the output sound 10 times louder.

Increase VLC volume using Dynamic Compressor Options

You can try raising the volume with VLC's dynamic compressor options. This approach compresses the louder sections of the audio signals while enhancing the silence regions.

You can go to the following steps  Tools > Effects and Filters [ CTRL + E]> Audio Effects > Compressor

What happens if you increase the VLC volume above 100%?

VLC includes an audio decoder that can change the digital audio data stream to increase the final audio output. VLC's final recommendation is 100%. However, while amplifying the signals beyond 100%, many high-frequency components of the audio are chopped out, resulting in distorted audio. If you notice any loss of audio sound, do not exceed 100%.

Conclusion

VLC media player allows its users to increase the max volume control to 300%. Yet, most of the time 80-100% is preferable. Although you can increase the volume up to 300%, it is not recommended to get a loud volume for your ears. Loudness enough to hear properly should be set so as to enjoy what you are watching.
