The Dangers of Deleting Microsoft Visual C++ Redistributable Libraries
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’.
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:
Let's go for the detailed steps:
1 Open VLC media player
Firstly, you need to open the VLC media player. Either through the application directly or by launching a video using VLC.
2 Click on Tools and then Preferences
On the Menu bar, click on the ‘Tools’ option. Then, click on the option ‘Preferences’. A new window will open after this step.
Or, simply you can press Ctrl+P
3 Check the box "All"
On the bottom left corner, check the box ‘All’ (within Show settings).
4 Click on Qt
On the left sidebar, you can find multiple drop-down options. Go to ‘Interface’. Then click on ‘Main interfaces’ to select the option ‘Qt’.
5 Set the maximum volume to 300%
In the Qt interface, scroll down to find the option ‘Maximum Volume displayed’. Change the value in the corresponding box from 125 to 300.
6 Save the settings
Finally, you will have to Save the changes and restart the VLC media player to see the changes.
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.
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.
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
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%.
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.
