Open the Advanced options menu for more advanced audio tweaking. Click on the Audio button. NOTE – The options you have selected in Audio/Video menu will be set here so there is no need to reset some of these options as a result.

AmbientFactor. Use this to set the volume level of ambient sounds in Rune. This value represents a fraction of SoundVolume, e.g. if AmbientFactor is set to .7 & SoundVolume is set to 255 then the ambient sounds are effectively played at 178. Valid entries are from 0 - 1.

DopplerSpeed. I’d recommend leaving this at the default value of 9000.

EffectsChannels. The higher the amount the more realistic the audio in Rune will be (more simultaneously playing audio channels). A lower setting may improve performance. I’d recommend setting this from 8 – 16 depending on your soundcard.

Latency. The default value for this is 40, I’d recommend try setting it to 0 instead. This should result in no delay for audio playback.

LowSoundQuality. Setting this to True forces 8-bit sound quality. This can improve performance (particularly with older soundcards, generally ISA), although will result in reduced audio quality. I’d highly recommend leaving this set to False for improved audio quality & very little performance difference on newer soundcards.

MusicVolume. Use this to set the volume level for music. 255 is the highest value that can be used. Lower values will result in lower music volume. This setting is irrelevant if you set UseDigitalMusic to False.

OutputRate. The higher this setting the higher quality the audio. 44100Hz is CD quality. 22050Hz is optimal for MMX machines. If you are desperate for extra performance try setting it to 11025hz, although this is not recommended.

ReverseStereo. Set this to True to swap speaker positions for game audio, i.e. left speaker becomes right & right speaker becomes left. This setting is best left set to False unless you find that audio is playing from the wrong speakers.

SoundVolume. Use this to set the volume level for audio. 255 is the highest value that can be used. I’d recommend setting this to the maximum value of 255 & independently adjust the volume levels for music & such.

Use3dHardware. Set this to True to enable EAX/A3D support. With A3D2/3 capable cards there can be quite a performance hit when enabled (compared to EAX that is). This will yield improved audio quality. For optimal performance set this to False.

UseCDMusic. Setting this to True will allow you to play music from an audio CD in the game.

UseDigitalMusic. Set this to False to disable the in-game music from playing. This will improve performance very nicely. I’d highly recommend doing so.

UseDirectSound. Set this to True to improve performance. Setting it to False can fix audio problems with older (ISA in most cases) soundcards.

UseFilter. Set this to True to enable audio filtering for improved audio quality, improve performance by setting it to False.

UseReverb. Set this to True to enable reverb effects. You can improve performance by setting it to False (especially with A3D2 capable cards), this will disable the reverb effects.

UseStereo. Set this to True for improved audio quality where appropriate.

UseSurround. If you have a Dolby Surround sound receiver e.g. Dolby Pro Logic, then set this to True, so you may take advantage of 360-degree Dolby sound panning. Otherwise, set it to False.
