I will be adding to this guide over the coming weeks when I have time. Thank you for your patience :)

Output Settings

• Music volume: 0% - 10%.
  
• Dynamic range compression: Optional - Enable if things get too loud when there's a lot of sounds playing. Disable if you want everything to be as raw and loud as possible.
  
• Voice chat volume: 100% - 200%.
  
• Directional voice chat: Enabled.
  
• Voice chat attenuation: Optional - Enable if voices are too hard to hear over sounds like vents.

Input Settings

• Input mode: Voice activity.
  
• Microphone volume: Reduce until the voice activity meter fills up to no more than roughly 70% when speaking at a normal volume but still hits 100% when yelling. The greater this contrast, the better that reverb thresholds and settings like "Scream Mode" (Voice tab) will work.
  
• Cutoff prevention: 250ms - 500ms.

Focus Target Audio (General tab): This setting moves the position of your ears to whatever target is focused by the camera. If enabled, controlling a turret transports your ears outside the submarine. In this scenario, you can no longer hear what's happening around your character - with the exception of local voice chat (toggleable with the "Hear Voices On Turrets" option in the Voice tab).

Unsubmerged Distortion Gain (Dynamic tab): If you find gunshots too loud, reducing this setting will help.

Indoor Reverb Strength (Dynamic tab): The easiest way to control the "echo" effect for indoor areas.

Scream Mode (Voice tab): This is a fun setting that makes local proximity chat distance scale with volume. Scream for help!

Custom Radio Presets (Voice tab): It's worth messing around with the radio filter to see what you like. There's a handful of preset options to start with.

Submerged Pitch (Pitch tab): If you don't like sounds being pitched lower in the water, this is the setting to change.

Show Performance (Advanced tab): If you're interested in how many frames per second the mod is costing you.

Custom Sounds (Advanced tab): More advanced to use but very powerful - apply distortion, sidechaining, and mixing to any sound in the game on an individual level.

Being able to manually edit the properties of sounds is a powerful tool for customization and necessary for guaranteed compatibility with other mods.

The properties of a sound can be modified by inserting a fragment of its filename into a list.

The basic process is as follows:

1. Find a uniquely identifiable keyword in the filename of the sound.
   
2. Find the property you want to change in the Advanced tab.
   
3. Add that keyword to the property's list.

Q: How do I find a uniquely identifiable keyword for a sound?
Enable "Show Playing Sounds" in the Advanced tab. When your sound plays, it's full filename will be listed. I recommend taking a screenshot so you have time to read it.

Available Properties

• Custom Sounds - This list is unique because it requires entering more than just a keyword. Instead, a single keyword is associated with multiple properties bundled together for convenience.
  
• Ignored Sounds - Ignore all effects and processing.
