Template:Otherlang2 In the context of Half-Life 2 and other Source games, DSP, or Digital Signal Processor, refers to the audio effects such as echoes, reverberation and similar which can be applied to currently playing sounds. DSP effects are automatically handled depending on the materials around the player, and can be overridden with soundscapes (env_soundscape).
