This is the only required field.
the sound path for the sound to play

used to calculate a distance for when the sound fades and cannot be heard from

the identifier of the sound, if nil it will use the soundPath field as the identifier

the tick in which the sound was started, this value is used to synchronize the sound for all players. Defaults to the current tick

the entity the channel should follow, defaults to the world entity

the volume of the sound, defaults to 1

if the sound should be looped or not, defaults to false

the callback function that is called when the channel was created. The channel is given to the callback as the first argument

the minimum distance for the sound to start fading

the maximum distance after which the sound cannot be heard anymore

the distance at which the sound should begin to be hearable, default 0. Close up the sound is fully audible. This allows you to make sounds only audible at a certain distance, meaning if you're closer than this distance, it cannot be heard

the distance at which the sound should be fully audible, default 0

a position to play the sound from. If an entity is set it will override this position, however if the entity has not networked yet this ensures the sound starts at the correct position

any additional modes to pass to SlashCo.AudioSystem.CreateChannel

the sound pan. See https://wiki.facepunch.com/gmod/IGModAudioChannel:SetPan

the sound playback rate

won't automatically play the sound

if set, a hook is called allowing you to add a hook that is executed when a sound is played:
hook.Add("SlashCO:AudioSystem:PlaySound:ExampleGroup", "Example", function(soundData, channel) end)

if true, the channel is deleted once the sound finished playing. This ignores the looping flag and still stops it

how many seconds it takes for the sound to fade in at the start

how many seconds before the ending it should start to fade out, and when it faded out the channel is destroyed

how many seconds after the sound starts it should begin to fade out. Use a negative number to use a time based off the end of the sound instead of the start

forces the sound to play as mono. Preferably use forceStereo since it won't reduce sound quality

forces the sound to play as stereo. This does not truly force stereo, but removes mono or 3D flags if they were set

if set it will use the entity's EyePos instead of falling back to WorldSpaceCenter

if set it will calculate the pan for the channel, giving the sound a fake 3D effect

the fallback sound when the bound ConVar is disabled

a ConVar the sound is bound to. When the ConVar is false it will instead play fallbackSoundPath

if set, the entity index is not added to the identifier, allowing the sound to only be played once globally instead of once per entity

if set, the channel won't be removed after the entity attached to the channel is removed

if set, traces are used to change the volume and position based on the environment. Experimental and performance intensive

a string containing all channel groups that should be modified while this channel is playing

the volume multiplier that should be enforced onto all channels in modifyGroup

not implemented. Time in seconds for the volume to fade to the enforced multiplier. Clamped between 0 and 30

a table for the pulse effect. This feature is still experimental and should not be used

an entity that should pulse

the class of all entities that should pulse, such as sc_gascan

the sound frequency that should be checked for. Currently unused

internal field set if the sound was sent by the server

to which team the sound should be sent to.
Important Internally this just sets sendToEntity with the table of players.

The table or the player to send the sound to
