cfsndserv - crossfire client sound server
adjusts and mixes sounds before playing them
none - started automatically by crossfire client
~/.crossfire/sndconfig can contain the following options:
- 1 means stereo sound, 0 - mono
- bitrate of generated sound - 8 or 16
- if we should sent signed data to the soundcard. 1 means
- speed of playing data. This should be 11025, or sound pitch
- how many buffers to allocate
- how big the buffers should be. buffers*buflen shouldn't be
smaller than the longest sound to be played.
- home many sound can be played at the same time. When this
setting is bigger, each sound volume will decrease.
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
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
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.
