CFSNDSERV(6)

NAME
cfsndserv - crossfire client sound server

DESCRIPTION
getzone adjusts and mixes sounds before playing them

USAGE
getzone none - started automatically by crossfire client

CONFIGURATION OPTIONS
~/.crossfire/sndconfig can contain the following options:

stereo
    1 means stereo sound, 0 - mono

bits
    bitrate of generated sound - 8 or 16

signed
    if we should sent signed data to the soundcard. 1 means yes.

frequency
    speed of playing data. This should be 11025, or sound pitch will change

buffers
    how many buffers to allocate

buflen
    how big the buffers should be. buffers*buflen shouldn't be smaller than the longest sound to be played.

simultaneously
    home many sound can be played at the same time. When this setting is bigger, each sound volume will decrease.

HOW DOES IT WORK?
The sound server gets information about sounds to be played on standard input.

The information is a line: <sound number> <sound type> <relative x> <relative y> All those numbers are hex. The file ~/.crossfire/sounds contains description of sound numbers and types. For example:

3 0 5 0

Means that normal sound SOUND_FUMBLE spell should be played as it's source was5 units to the right of player.

Sounds are mixed in special buffers, which are in fact one buffer, which should be big enough for the biggest sound to be played.

The buffers, if contain anything, are sent one by one to the sound device. Each buffer is cleaned after playing.

Sounds data is multiplied by some ratio (<1) evaluated from it's position and volume and added to the buffers, starting from the next after the one being played.

So bigger buffer means bigger delay, before th sound is actually played, but the smaller buffer is, the bigger is possibility, we won't succeed filling the next buffer, before last is played.
