Sound Booster has the ability to amplify sound volume for any Windows application, even when the current system volume is already at its maximum setting. There are instances where you raise the volume to its highest level but still struggle to hear the audio clearly. Sound Booster for PC addresses this by enhancing the sound output of any video played through a web browser, effectively increasing its loudness.

The Sound Volume application is designed to make even the tiniest and least audible speakers produce a louder sound. This means that if you're having difficulty hearing someone on the other end, you can conveniently elevate the volume beyond the system's established maximum limit.

If your intention is simply to occasionally enhance the volume for quiet videos or music, there's a good chance that investing in new speakers might not be necessary. Utilizing Sound Volume PC Booster allows you to amplify the audio in the Windows operating system by up to 500% of the original level.

Gone are the days when you were constrained by your PC's sound card limitations when it came to amplification. You can now increase the volume to your preferred level, even if the system volume is already set to its maximum. Letasoft Sound Booster actively processes all audio being played on the system, boosting it before it reaches the sound card.

Considering purchasing external speakers for your laptop? It might be worthwhile to reconsider your plans. If your laptop's audio is generally satisfactory but you face challenges with specific programs or media content that play at low volume, the Windows Sound Booster tool can provide a solution.

This free application is ideal for elevating the sound output of a web browser, media player, game, or any other sound-emitting Windows program. Your software can be used as usual, with no special adjustments needed. The tool operates in real-time without the necessity for manual configuration, plugins, or add-ons.

Features and Highlights

Enhanced Volume Beyond Limits
The application empowers you to amplify the sound of any running program within the system by an impressive 500%. It's effective at elevating the volume of various software like web browsers, online communication tools (such as Skype, MSN, Live), diverse media players, and games. In essence, the app can enhance the volume of virtually any Windows-based program capable of producing audio, ensuring a comfortable auditory experience.

User-Friendly Functionality
Managing the current volume is a breeze through the intuitive pop-up slider located in the system tray. Additionally, you have the option to set system-wide hotkeys for both volume increase and decrease, granting you quick control over audio adjustments whenever needed.

Automatic Startup
The application offers the convenience of automatic launch during every Windows startup, eliminating the need for manual initiation. This feature proves beneficial if your PC's speakers tend to be insufficiently loud for most scenarios.

No sound distortion
Letasoft Sound Booster diligently monitors the ongoing gain levels, safeguarding against sample clipping and minimizing prominent sound distortions that can arise.

Two different methods for boosting sound
The program adopts two distinct techniques for raising sound volume: code injection and APO (Audio Processing Object) effects. Each method carries its own advantages and disadvantages. By default, both methods are enabled to accommodate a wide range of playback scenarios. Furthermore, there's an option to activate SuperBoost, which may offer an additional boost but could potentially introduce minor sound distortions. Nonetheless, it's a worthwhile option to explore, particularly if you're aiming for maximum volume intensity.


Will Sound Booster enhance the volume of my preferred program, X?
Yes, it can amplify the volume of any Windows application, such as web browsers or media players.

Which operating systems are compatible with Sound Booster?
It supports all major Windows operating systems: Windows XP/Vista/7/8/10/11, both 32-bit and 64-bit.

How does Sound Booster function?
The app interacts with every application in the system that produces sounds, processing the audio output stream before it reaches the input of the sound card.

What do I need to activate Sound Booster?
To activate the tool, you'll require the product key that was emailed to you upon purchasing the software, as well as an active internet connection.

How can I set up Sound Booster to start when Windows launches?
Right-click the app icon in the system tray, select "Settings," and in the opened dialog, enable the "Start on Windows startup" option. Enabling this will ensure Sound Booster starts automatically with Windows.

Why does the sound level sometimes revert to the original level?
If you're using the trial version of Sound Booster, it temporarily pauses sound amplification for 5 seconds every 5 minutes as a limitation.

Why am I experiencing sound distortion while using Sound Booster?
Sound Booster's performance relies on your PC's speaker capabilities. If distortion occurs, consider reducing the boost level slightly. Updating to the latest version may also address this issue.

How can I assign a hotkey to adjust the sound amplification?
Right-click the app icon in the system tray, choose "Settings," and in the dialog, you can set hotkeys for increasing and decreasing the boost level.

Sound Booster isn't affecting my sound. What should I do?
Ensure the "Enable" checkbox is selected and the boost level slider is set to its maximum at 500%. Experiment with different Boost Modes and consider trying the SuperBoost setting if necessary.

Why does my computer slow down when the Sound Booster is active?
While sound boosting is generally not CPU-intensive, it might affect low-spec computers. Avoid using the "Injection and APO effect" boost mode, and consider disabling the Compressor setting to reduce CPU usage.

Can I upgrade to the latest version for free?
If you purchased the app within the last year, you're eligible for a free upgrade to the latest version.

How can I upgrade to the newest version?
Right-click the app icon in the system tray, choose "Check for Update..." and press the "Check" button in the "Check for Update" dialog. This feature requires an internet connection.
