Todo: There needs to be a brief description or link to a tutorial or guide on how to take an existing .wav file and make it accessible to the Hammer Sound Browser or Face Poser.
Sound in Source can be processed in many ways. It can emit from a location in the world, have its pitch or volume altered, trigger behaviours from NPCs, and be lip synced.
Entities
- ambient_generic — this is the basic entity to play a specific sound or soundscript, including music.
- ambient_music —
audio in the music layer, overriding music queued by the AI Director. - env_soundscape — for playing background noises and ambience. (see Soundscapes)
- env_soundscape_proxy Point entity that acts like a soundscape but gets all of its sound parameters from another env_soundscape entity.
- env_soundscape_triggerable Point entity just like env_soundscape except that it works in conjunction with the trigger_soundscape entity to determine when a player hears it.
- trigger_soundscape Brush-based soundscape trigger. Does not need outputs, as it automatically triggers the soundscape specified by its Soundscape property.
- env_microphone — detects sounds.
- env_speaker — plays sounds based on a set of Response System rules.
- scripted_sentence — used to make an NPC speak an idea.
- sound_mix_layer — used to set a mix layer to a specific value.
- logic_choreographed_scene — used for conversations and other sequences. See Category:Choreography.
Articles
- Category:Sound System — how sound works in Source.
- Soundscripts — advanced sound usage in Source.
- Hammer Sound Browser — documents the Hammer user interface for browsing sounds.
- Soundscapes — background sounds and ambience.
- Sound sensitive trigger — how to trigger an event based on the loudness.
- Startup Music — one way to add music to a mod's title screen (alternatively, put it in a Menu Background Map).
AI sounds
- AI sounds are not audible to the player; they are purely an AI construction. They can be placed in-map with the ai_sound entity.
Music
- Creating your own music — composing and adding music to a mod.
Materials
To specify the set of sounds for a custom material (the noises produced in response to hits, scrapes, etc), see Material surface properties.
Notes
- To play music, use Hammer Sound Browser to search for keyword
music. - Many entities can have sounds assigned to them. For example, prop_door_rotating can be assigned sounds for opening, closing, swinging, being locked, and being unlocked. See the individual entities for details.
