SRS Wow is an audio-enhancement suite made up of three SRS technologies:
- SRS 3D: SRS Labs calls this "wide stereo imaging and nonfatiguing headphone listening mode." In English, it breaks down like this: When you're listening to headphones, the sweet spot is actually in the center of your head. SRS 3D widens this area of sound so that the music isn't so concentrated in one small spot and makes it sound more as if you were listening in an open environment.
- Focus: "Sound-image elevation used in combination with SRS to create a large sound image"--originally conceived for in-car listening, this effect is designed to lift the sound up near your head, something needed in a vehicle where speakers are (or were) generally placed at hip or ankle level.
- TruBass: "Psychoacoustic bass enhancement to enable deeper, natural bass of audio source material to be perceived over small speaker drivers." This one's my favorite. Essentially, TruBass uses acoustic trickery to make your brain believe that you are hearing bass that is actually in the song but that the hardware (usually headphones) is incapable of creating.
