detect_voices[edit]

type: yes / no

yes = Allegro will attempt to autodetect the number of hardware voices available

no = Allegro will use a specified default number of voices

  • NOTE: this setting only works in the DOS version of Eternity.

snd_card[edit]

type: named values

values:

  • DOS: autodetect, none, SB, "SB 1.0", "SB 1.5", "SB 2.0", "SB Pro", SB16, GUS
  • Windows: SDL_mixer, none

value = type of sound driver to be used by Allegro/SDL

  • autodetect = Allegro will attempt to autodetect the card type (DOS only)
  • none = digital sound will be disabled

mus_card[edit]

type: named values

values:

  • DOS: autodetect, none, adlib, OPL2, 2xOPL2, OPL3, "SB MIDI", MPU-401, GUS, DIGMID, AWE32
  • Windows: SDL_mixer, none

value = type of MIDI driver to be used by Allegro/SDL

  • autodetect = Allegro will attempt to autodetect the synthesizer (DOS only)
  • none = MIDI output will be disabled

sfx_volume[edit]

type: integer

value range = 0 - 15

value = base volume for digital sound effects

music_volume[edit]

type: integer

value range: 0 - 15

value = base volume for MIDI synthesis

s_flippan[edit]

type: on / off

on = forces reversal of stereo sound channels

off = stereo sound will be normal for the card/driver/other settings

  • NOTE: on and off for this variable do not equate to flipped or non-flipped in the same way for every combination of sound card and/or Allego configuration. If your sound is right, turning on s_flippan will make it wrong. If your sound is wrong, try this to make it right.

s_precache[edit]

type: on / off

on = sounds will be precached at the beginning of the game

off = sounds will be loaded as they are used

  • NOTE: off will make load times shorter, but may degrade performance. on may require more system memory.

s_pitched[edit]

type: on / off

on = enable variable-pitched sound effects

off = sounds always play at real pitch

snd_channels[edit]

type: integer

value range: 0 - 128

value = number of software channels to maintain

  • NOTE: this has nothing to do with the number of available hardware channels, which, unless you are very rich, is probably nowhere near 128 :P

This value affects the number of sounds the game will *attempt* to play at one time. If set too low, you will lose sound unnecessarily. Setting it too high will use more memory and take more time to process.

snd_spcpreamp[edit]

type: integer

value range: 1 - 6

value = amplification factor for SPC music.

snd_spcbassboost[edit]

type: integer

value range: 0 - 31

value = logarithmic bass boost scale for SPC music.
