Sound booster means raising overall PC playback so quiet videos and thin laptop speakers sit louder. Install FxSound from GitHub Releases or winget, open it, and add gain. Skip Softonic, CNET, and unofficial wrappers. Files stay on GitHub. This site does not host the installer.

Bass booster is the low end. Sound booster is the whole level. If you only wanted more kick, use Bass booster. A system-wide comparison sits on Equalizer vs Equalizer APO. Windows 11 install sits on Equalizer Windows 11.

Install a sound booster on Windows

Paste this into Windows Terminal or Command Prompt:

winget install -e --id FxSound.FxSound

Copy

If winget is missing, install App Installer from Microsoft, then paste again. Official Microsoft links only. GitHub Releases is the other path. For most PCs take fxsound_setup.exe. ARM: fxsound_setup.arm64.exe. Live tag observed: V1.2.13.0. File list sits on Equalizer releases. LICENSE sits on Equalizer GitHub.

How to use a sound booster

Install FxSound with the command on this page, or fxsound_setup.exe from GitHub Releases.
Open FxSound. You should get a window, not a browser tab.
Play a quiet clip you already know. YouTube at 30 percent, a laptop speaker, a thin voice memo. Keep Windows volume in the middle so you still have a way down.
Raise overall level in the app. The clip should sit forward. If it only got boomier, you moved bass, not a sound booster. Put the low end back and raise the whole level instead.
If it crackles or the speaker fizzes, turn the app down. Then turn Windows down if it is still hot. Distortion is the limit, not a badge.

That list is the sound booster path. You still have Windows volume. The app is extra gain on top. Two knobs. You need a way to get quieter in a hurry.

Quiet videos, calls, and a laptop at 100

Some uploads are mastered quiet. Windows at 100 is already the ceiling. A sound booster is for that ceiling, not for a party. If Windows is at 40 and you add a pile of gain, you skipped the simple step. Turn Windows up first. Add the app when 100 is still too thin.

Calls are voices. A sound booster that also hisses the room mic playback is too far. Test with a call you can hang up. If the other person sounds like a speaker in a bathroom, turn it back.

Night volume is still volume. Headphones leak. If someone else is in the room, ask. The program will not.

Clipping, hiss, and two volume knobs

Clipping is a hard edge on peaks. Hiss is the noise floor coming up with the signal. A sound booster raises both. If the file was noisy, it gets noisier. That is the file, not a broken install.

Leave Windows below 100 so you can drop it with one key. If the app is the only volume and Windows is pinned, you lose the easy out. Two knobs on purpose.

Bluetooth adds its own limiter. A sound booster plus a cheap dongle is a mess. Test on the speaker jack or the built-in speakers first so you know which device is clipping.

What this sound booster will not do

It will not be a hardware amp. It will not fix a blown driver.

It will not replace turning Windows up. It will not make a legal quiet mix into a club without also raising noise. It will add gain to playback on this PC.

Ears

If your ears ring, stop. A sound booster is easy to overdo because the first second feels fine. Play a minute. Then decide. We will not invent a safe number. You know if it hurts.

Quiet files versus quiet speakers

A quiet YouTube encode is not the same job as a thin laptop speaker. Sound booster raises overall playback. It does not restore missing bass. It does not fix a file that was mastered quiet on purpose. Play a clip you know. Raise overall level a little. Leave Windows volume where you can still turn it down.

Night listening is where people overdo it. Headphones at a high Windows volume plus more gain in the app is how you wake the house and hash the clip. Start low. If a meeting app already has its own boost, stack less here. Two loudness tools on the same stream will clip.

Normalization in a player is a different tool. Some players raise quiet tracks toward a target. This page is the system playback after that. If the player already boosted the file, add less in FxSound. Stop if it distorts. Turn the app back. Then Windows.

Meetings, Bluetooth, and the wrong device

A call already has AGC. Adding a sound booster on top can make you sound loud and crunchy to other people. Test with a local file first. If you only needed kick, use Bass booster. If you needed Windows 11 install notes, use Equalizer Windows 11.

Pick the device you hear. HDMI, USB, onboard, Bluetooth. Boosting the wrong endpoint sounds like the page did nothing. Bluetooth can already compress. A wired output is the honest test. If it still distorts on wired, you added too much gain, not a codec bug.

When to stop

If the quiet parts are fine and the loud parts hash, you hit the ceiling. Turn the app down. Do not raise Windows to compensate. A ringing ear is a stop. We will not invent a safe decibel. Uninstall is Apps in Windows or the GitHub app uninstall. Quitting the window is not uninstall.

Fetch again from GitHub Releases or winget. Skip Softonic, CNET, and unofficial wrappers. The exe names are fxsound_setup.exe and fxsound_setup.arm64.exe. Match the machine.

GitHub Releases is the file host. Winget is the other honest path. The command is winget install -e --id FxSound.FxSound. Match fxsound_setup.exe on x64 and fxsound_setup.arm64.exe on ARM. Read the live tag on the release page. We last saw V1.2.13.0. Skip a renamed setup from search.

How do I use a sound booster?

Install with winget install -e --id FxSound.FxSound or fxsound_setup.exe. Open it. Play a quiet clip. Raise overall level. Leave a way to turn Windows down. The install pointer is Install on the home page.

Is a sound booster the same as a bass booster?

No. Sound booster is overall loudness. Bass booster is the low end. Same install. Different job.

Why does my sound booster crackle?

You hit the speaker or the file. Turn the app down. Then Windows. Test on another output if you have one.

Did you make this sound booster?

No. The FxSound team publishes FxSound under AGPL-3.0. Official files live on GitHub Releases. This site only points at that page. We do not host the installer.
