Collaboration diagram for channel_t:

Data Fields
float	basespeed
	playback rate multiplier for pitch variation

float	basevolume
	0-1 master volume

vec_t	distfade
	distance multiplier (attenuation/clipK)

int	entchannel
	which channel id on the entity

int	entnum
	makes sound follow entity origin (allows replacing interrupting existing sound on same id)

void *	fetcher_data
	Per-channel data for the sound fetching function.

unsigned int	flags
	cf CHANNELFLAG_* defines

float	mixspeed
	these are often updated while mixer is running, glitching should be minimized (mismatched channel volumes from spatialization is okay) spatialized playback speed (speed * doppler ratio)

vec3_t	origin
	origin of sound effect

double	position
	updated ONLY by mixer position in sfx, starts at 0, loops or stops at sfx->total_length

int	prologic_invert
	whether a sound is played on the surround channels in prologic

struct sfx_s *	sfx
	pointer to sound sample being used

float	volume [SND_LISTENERS]
	spatialized volume per speaker (mastervol * distanceattenuation * channelvolume cvars)
