Get to know the Advanced Features of FxSound
Discover the unique and powerful advanced features that make FxSound stand out. These features are designed to enhance your experience and provide added functionality.
Adjustable 5–31-Band Equalizer
Choose How Much Control You Need Over Your SoundFxSound lets you adjust the equalizer from 5 up to 31 frequency bands, so you can choose between simple tuning and much finer sound control. Fewer bands make broad adjustments easier, while additional bands help you work on narrower parts of the frequency spectrum. Current FxSound versions also use ISO-compliant EQ band frequencies for a more structured layout. This flexibility lets you adapt the equalizer to your experience level, playback device, and listening preferences.
Advanced EQ Fine-Tuning Controls
Shape Frequencies With Greater AccuracyBeyond changing individual EQ bands, FxSound provides Master Gain, Filter Q, Balance, and Normalization controls for more detailed audio adjustment. Filter Q lets you control how broadly or narrowly an EQ change affects nearby frequencies, while Master Gain helps you manage the overall signal after making boosts or cuts. Balance gives you control over left and right output, and normalization helps manage level consistency. Together, these tools give you considerably more control than a basic fixed-band equalizer.
Custom Preset Creation and Management
Save Your Own Sound Instead of Rebuilding It Every TimeOnce you find an EQ and effects combination that works for you, FxSound lets you save it as a custom preset for future use. You can modify existing presets, save your changes as new profiles, overwrite older custom presets, or remove profiles you no longer need. FxSound also supports preset import and export, which is useful for backing up your preferred sound or moving presets between computers. This makes repeated tuning much faster when you regularly use the same listening setups.
Device-Specific Preset Assignment
Match Different Sound Profiles to Different Output DevicesFxSound can associate an output device with a particular preset, helping you maintain different sound profiles for different listening hardware. For example, your headphones may need a different EQ and effects setup from your desktop speakers. When the preset associated with the active output device changes, current FxSound versions can apply that preset directly. This reduces the need to manually rebuild or search for the right profile whenever your listening device changes.
Preferred Output Device Priority
Keep Your Preferred Speakers or Headphones at the Top of the Audio ChainFxSound lets you assign priority to output devices instead of treating every connected device equally. If your preferred device is available when FxSound starts, audio can automatically use it; if it disconnects, FxSound can move to another available device and return when the preferred device becomes available again. Current versions also display output devices according to their configured preference order. This is particularly useful when your Windows PC regularly switches between speakers, headphones, monitors, and other audio outputs.
Command-Line Control
Control FxSound From Scripts and More Advanced WorkflowsFxSound includes command-line options for users who want to control the application without relying entirely on its graphical interface. Current releases support commands for presets, output devices, EQ band frequency and gain, effect levels, and application status, including applying commands to an already running FxSound instance. You can also launch FxSound minimized to the system tray. These controls are useful when you want to incorporate FxSound into scripts, shortcuts, or more customized Windows workflows.
Automatic Preset Saving and Recovery Controls
Keep Your Adjustments Without Constantly Saving Them ManuallyFxSound can automatically save preset changes when you modify the equalizer or effects, reducing the chance of losing a sound profile you have been refining. If your adjustments do not work as expected, the application also provides controls for resetting unsaved changes and restoring audio settings to their defaults. This gives you more freedom to experiment without making every change feel permanent. It is especially useful when you frequently test different EQ and processing combinations.
Some Key Features of FxSound
Explore the essential features of FxSound that make it a top choice. These key features are designed to provide ease of use, efficiency, and versatility.
System-Wide Audio Enhancement
FxSound processes compatible Windows playback at the system level, so you can enhance audio from music, browsers, videos, games, and other applications without configuring a separate equalizer inside each one. This gives you a more consistent listening profile across your PC.

Bass Boost
FxSound's Bass processing helps you increase low-frequency presence when your speakers or headphones sound thin or lack impact. You can add more depth and punch without relying only on Windows volume controls.
Clarity Enhancement
Clarity processing focuses on the tonal detail of your audio and can make vocals, dialogue, and higher-frequency information easier to notice. It gives you a simple way to brighten or define playback without manually tuning several EQ bands.
Dynamic Boost
Dynamic Boost helps increase perceived volume and restore some of the amplitude affected by compressed audio. It is useful when playback feels weak or lacks energy, especially when simply increasing the Windows volume does not provide the presentation you want.
Ambience Effect
FxSound's Ambience control adds a greater sense of acoustic space to your playback. You can use it when you want music, movies, or other content to feel less dry and more spacious without manually building a complex effects chain.
Surround Sound Effect
The Surround Sound control is designed to give playback a wider, more spatial presentation. It can make supported music, movies, and games feel more immersive when a broader sound field suits your listening setup.
Built-In Audio Presets
FxSound includes ready-made presets for General, Music, Voice, Streaming Video, Gaming, Classic Processing, Light Processing, and Bass Boost. These profiles give you quick starting points for different types of content, so you do not need to build every sound profile manually.
Playback Device Switching
You can select your active playback device directly from FxSound and switch between supported speakers, headphones, and other outputs. Device switching is also available through keyboard shortcuts and the Windows system-tray menu, making frequent output changes faster.
Volume Leveling
Current FxSound releases include volume leveling with an adjustable 0.0 to 4.0 dB range. This gives you another way to manage playback-level differences and achieve a more controlled listening level without relying exclusively on EQ or Dynamic Boost.
