Hi everyone,

I am trying to make a sound louder using SoundEmitToAll() from a player entity:

EmitSoundToAll("pathToMySound", client);

sdktools_sound.inc lists the parameters of level and volume as follows:

enum
{
	SNDLEVEL_NONE = 0,			/**< None */
	SNDLEVEL_RUSTLE = 20,		/**< Rustling leaves */
	SNDLEVEL_WHISPER = 25,		/**< Whispering */
	SNDLEVEL_LIBRARY = 30,		/**< In a library */
	SNDLEVEL_FRIDGE = 45,		/**< Refrigerator */
	SNDLEVEL_HOME = 50,			/**< Average home (3.9 attn) */
	SNDLEVEL_CONVO = 60,		/**< Normal conversation (2.0 attn) */
	SNDLEVEL_DRYER = 60,		/**< Clothes dryer */
	SNDLEVEL_DISHWASHER = 65,	/**< Dishwasher/washing machine (1.5 attn) */
	SNDLEVEL_CAR = 70,			/**< Car or vacuum cleaner (1.0 attn) */
	SNDLEVEL_NORMAL = 75,		/**< Normal sound level */
	SNDLEVEL_TRAFFIC = 75,		/**< Busy traffic (0.8 attn) */
	SNDLEVEL_MINIBIKE = 80,		/**< Mini-bike, alarm clock (0.7 attn) */
	SNDLEVEL_SCREAMING = 90,	/**< Screaming child (0.5 attn) */
	SNDLEVEL_TRAIN = 100,		/**< Subway train, pneumatic drill (0.4 attn) */
	SNDLEVEL_HELICOPTER = 105,	/**< Helicopter */
	SNDLEVEL_SNOWMOBILE = 110,	/**< Snow mobile */
	SNDLEVEL_AIRCRAFT = 120,	/**< Auto horn, aircraft */
	SNDLEVEL_RAIDSIREN = 130,	/**< Air raid siren */
	SNDLEVEL_GUNFIRE = 140,		/**< Gunshot, jet engine (0.27 attn) */
	SNDLEVEL_ROCKET = 180,		/**< Rocket launching (0.2 attn) */
};


#define SNDVOL_NORMAL		1.0		/**< Normal volume */

stock void EmitSoundToAll(const char[] sample,
				 int entity = SOUND_FROM_PLAYER,
				 int channel = SNDCHAN_AUTO,
				 int level = SNDLEVEL_NORMAL,
				 int flags = SND_NOFLAGS,
				 float volume = SNDVOL_NORMAL,
				 int pitch = SNDPITCH_NORMAL,
				 int speakerentity = -1,
				 const float origin[3] = NULL_VECTOR,
				 const float dir[3] = NULL_VECTOR,
				 bool updatePos = true,
				 float soundtime = 0.0)

My guess is that the volume should be set as a factor of SNDVOL_NORMAL (e.g. 2 making the sound twice louder).

I tried playing with different values but setting a volume other than 1.0 mutes the sound completely and setting the level to a higher value doesn't seem to affect the sound.

Can someone please explain the relations between those two clearly? Documentation seems to be lacking on this subject.

Sound level represents the attenuation. That is, how far the sound carries before it fades to silence.
Sound volume is limited between 0-1 with 1 being full volume.

You can boost a sound's volume more by playing it multiple times in different channels.
