+
+## Class member overview
+
+### file
+This variable holds the name of the sound file in `.wav` format. It is used to specify which sound effect should be played. The file must be located in the `_work/Data/Sound/SFX/` directory, so the game can access it.
+
+### pitchOff
+The `pitchOff` variable sets the pitch offset in semitones. This allows you to adjust the pitch of the sound effect up or down, providing flexibility in how the sound is perceived in the game.
+
+### pitchVar
+`pitchVar` defines the semitone variance for the sound effect.
+
+### vol
+This variable controls the sound volume.
+
+### loop
+The `loop` variable enables or disables looping of the sound effect. When set to true, the sound will continuously repeat, which is useful for background sounds or ambient effects like fire or wind.
+
+### loopStartOffset
+`loopStartOffset` specifies the point in the sound file where looping should start. This allows for more precise control over which part of the sound effect is repeated.
+
+### loopEndOffset
+Similar to `loopStartOffset`, `loopEndOffset` defines where the looping should end. Together, these two variables allow you to create seamless loops by specifying the exact segment of the sound file to be repeated.
+
+### reverbLevel
+The `reverbLevel` variable sets the level of reverb applied to the sound effect.
+
+### pfxName
+This variable holds the name of the particle effect associated with the sound.

+## Class member overview
+Description of the class member variables.
+### volume
+The overall volume of the background music (soundtrack). This value ranges from 0.0 to 1.0, where 0.0 is completely muted and 1.0 is the maximum volume.
+
+### bitResolution
+Defines the sound quality in terms of bit depth. It can be either 8-bit or 16-bit, with 16-bit providing higher audio fidelity.
+
+### sampleRate
+Specifies the frequency at which the sound is sampled. This value ranges from 11050 Hz to 44100 Hz, with higher values offering better sound quality.
+
+### useStereo
+A flag indicating whether stereo sound is enabled. A value of 1 means stereo sound is used, while 0 means mono sound.
+
+### numSFXChannels
+Determines the number of sound effect channels available. This value ranges from 1 to 32, allowing for multiple sound effects to be played simultaneously.
+
+### reverbBufferSize
+Specifies the size of the reverb buffer, which affects the quality and duration of the reverb effect in the game's audio.
+
+### used3DProviderName
+Name of the 3D sound provider. One of the constants defined in [`Scripts/System/_intern/SFX.d`](https://github.com/VaanaCZ/gothic-2-addon-scripts/blob/Unified-EN/_work/Data/Scripts/System/_intern/SFX.d#L4-L15).
