Advanced sound options

The advanced sound options menu in Doom II.

The advanced sound options menu allows to fine-tune certain sound system settings. Its MENUDEF name is AdvSoundOptions and it can be summoned with the menu_advsound console command.

• Sample rate (Default/4000 Hz/8000 Hz/11025 Hz/22050 Hz/32000 Hz/44100 Hz/48000 Hz)

snd_samplerate

Chooses which sample rate to use. The default uses the system's default sample rate.

• Buffer size (Default/64 samples/128 samples/256 samples/512 samples/1024 samples/2048 samples/4096 samples)

snd_buffersize

Defines how many samples are buffered. If the sample rate is below 44100 Hz, long sound latencies may happen unless the buffer size is decreased. The default size corresponds to 1024 samples.

• Buffer count (Default/2—12 by 1 increments)

snd_buffercount

Defines how many buffers are used. The default number corresponds to 4.

OPL synthesis

• Only emulate one OPL chip (On/Off)

opl_onechip

This allows to limit the OPL emulator to only one OPL2 chip instead of two. One chip is not really enough to play Doom's music, and most old sound cards had either two OPL2 chips or one OPL3 chip (which acts like two OPL2 chips), but it can make the emulation up to twice as fast.

GUS Emulation

(development version r3494+ only)

• MIDI voices (16—256 by 4 increments)

midi_voices

How many voices are available to the GUS emulator.

• Emulate TiMidity (On/Off)

midi_timiditylike

Whether the internal TiMidity should work in GUS emulation (by default) or remain closer to TiMidity and TiMidity++.

• Read DMXGUS lumps (On/Off)

midi_dmxgus

Whether DMXGUS lumps should be parsed.

• GUS memory size (Unlimited/256K/512K/768K/1024K)

gus_memsize

Which level of patch remapping should be used. If you want to use patch remapping, be warned that generally, only the 1024K hardware was considered.
