To boost sound, these free sound boosters use various tools, like Equalizer, Pre-Amplifiers, Volume Controller, etc. These tools are are good at boosting volume, but at the same time, they can also distort sound quality. So, use these tools carefully, specially the Equalizer, as it can completely change the various audio parameters like treble, bass, voice, etc., and introduce noise in audio.

Many of these mentioned sound boosters are media players with the ability to boost sound. They possess many common media player features, like: audio/video player, filter, playlists, jump forward/backward slider and buttons, etc. Apart from these common features, some of these players have some very interesting tools, namely: VR support, 360 degree player, online radio, online video player, media downloader, audio editors, etc.

My Favorite Sound Booster software For Windows:

DFX Audio Enhancer and VLC Media Player are my favorite sound booster software. Both of these provide considerable amount of boost with least noise. In DFX Audio Enhancer, you can boost sound level of whole system, irrespective of which media player you use to play music.

DFX Audio Enhancer

DFX Audio Enhancer is a free sound booster software for Windows. This software helps you boost sound levels of PC beyond 100%. This sound booster software takes over the default audio drivers of PC to boost sound. Due to this, you can play audio in any audio/video player and still get boosted sound levels.

To boost sound, you get various settings, like Dynamic Boost, Hyper bass, Ambience, Fidelity, 3D surround, etc. Each of these sound settings has a slider to change sound levels from 1 to 10. But, apart from Hyperbass, you cannot move slider beyond level 5 in other settings and 3D surround is completely disabled in this free version. To overcome these limitations, you will have to purchase its paid version.

This sound booster also provides some other useful options, such as:

• Listening Environment: Using this, you can either choose headphone or speaker options to get optimal sound. But, headphones option is disabled in this free version.
• Music Types: This option provides three music types, namely, music type 1, music type2, and speech.
• Presets: It lets you save multiple sound profiles, so that you can use them when needed.
• Equalizer: By using this option, you can boost various audio parameters up to 12 db.

Note: This software provides most of the options with some restrictions; however, the free version provides  good amount of sound boost.

VLC Media Player

VLC Media Player is a free and open source media player software for Windows. It is also one of the most popular media player software available. This media player can also be used as a sound booster, as it provides various settings that effect sound performance.

This software provides broadly two options to boost sound.

In first option, you just have to move the mouse scroll wheel in upward direction, while mouse is over its interface. By doing so, you will notice that the maximum sound level goes to 125% for audio files and 200% for video files. Thus, VLC provides 25% and 100% sound boost for audio and video files, respectively.

The second option is known as Adjustments and Effects. To open this tool, go to Tools > Effects and Filter. This will open a pop-up window, and the adjustment options are available under Audio Effects window. Here, you can make adjustments under the following options:

• Equalizer: VLC provides a 10-band equalizer. Adjust the equalizer bands according to the boost in audio you require. It also provides presets for music genre, like rock, pop, party, etc.
• Compressor: This option contains various options to tweak audio performance. But the only option that helps to boost sound is Makeup Gain option. It can boost audio output up to 22 db.
• Spatializer: It helps you boost sound by varying various audio parameters, like size, width, wet, dry, and damp. These options provide very minimal audio gain over original audio.

The main advantage of this media player is that it supports almost all of the audio formats, so you can easily listen and boost audio of any audio format. Unfortunately, you cannot save boosted audio with this volume booster software.

Equalizer APO

Equalizer APO is a free parametric/graphic equalizer for Windows that can be used to boost audio on your PC. It can be used to modify various audio parameters, like pitch, treble, bass, audio boost, etc. It works with all media players, as it boosts overall system sound. In this free audio booster software, you will get lots of options and settings to modify audio, which makes this software quite comprehensive, and a bit complicated as well.

Let us understand first how this software works before talking about sound boosting option:

When you open this software, you can view two panel: Tools Panel and Analysis Panel.

• In Tools panel, you can add various audio tools to modify overall PC audio output. Here you can add tools like: Basic Filters, Parametric Filters, Controls, Graphic Equalizer, Advanced Filters, etc.
• In Analysis panel, you can analyze audio output.  It lets you view Peak Gain, Latency, Channel, resolution, etc., and audio output Graph.

How to boost audio of PC using Equalizer APO:

To boost audio you will need to add various audio tools in the Tools panel of this software. Click the green + button to view and add audio tools from various categories.

• Add Graphic Equalizer to the Tools panel. You can either add 15 band, 31 band, or variable equalizer. You can vary the equalizer bands to boost audio output according to your choice. Just be careful with equalizer, as maxing up channels unevenly can really distort the output audio.
• Go to Basic filters and add preamp tool. In this tool, you can either boost sound by moving the knob or manually entering gain values. But, by using knob you can only boost sound up to 20 db, whereas manually, you can enter much greater values.
• In the Parametric Filter category, add the Low Shelf and High Shelf filters. In both of these filters, you get three knobs to change parameters like Gain, Centre frequency, Corner frequency, and Slope. You can adjust knobs or enter values manually to boost sound.

Apart from various audio tools, you can also choose various channel configuration (mono, 5.1 surround, 7.1 surround, stereo, quadraphonic, etc.) and Devices (headphones, speakers, etc.) to get optimum output sound using this free audio booster software.

GOM Media Player

GOM Media Player is another commonly used free media player for Windows, with the ability to boost sound. In this music booster freeware, you can play audio and videos of various formats, and then boost their audio. This software also provides some Advanced Settings, like filters, 3D effects, audio effects, output device settings, etc. You can access these advanced settings either by pressing F5 key or by pressing the Settings (preferences) icon near the top left corner of the interface.

This sound booster basically provides two methods to boost audio, namely, Volume and Control Panel. In Volume, you get a volume slider to increase/decrease volume. Unlike normal sliders, this slider can increase volume beyond 100% and go up to 150% level. But after 100% volume level, quality of audio starts deteriorating. Whereas, in Control Panel, you can boost audio in its Audio section. In the Audio Section, you can vary audio frequencies between -12 to 12 db by adjusting frequency sliders. But, it provides almost negligible audio boost. So, in my opinion, you should use Volume Controller to boost sound.

As a media player, it provides many interesting features, like 360 degree player, 360 degree VR mode, various interface skins, snapshot option, etc.

Clementine Music Player

This property makes this software stand out from other music players that use Equalizer to boost sound.
