About the 5.1 Surround Sound Test
Designed for home theater enthusiasts, gamers, and audiophiles. Tests Front Left, Center, Front Right, Subwoofer, and Surround Left/Right channels using true discrete multichannel audio or spatial binaural simulation.
Ideal 5.1 Speaker Angles & Placement Standards
According to ITU-R and Dolby speaker placement guidelines, a balanced 5.1 surround sound configuration requires the following speaker layout relative to the primary listening position:
Center Channel (0°)
Directly in front, above or below TV screen at ear level.
Front Left & Right (±22° to ±30°)
Equidistant from the screen, forming an equilateral triangle.
Surround Left & Right (±110° to ±120°)
Positioned to the sides and slightly behind the listener, 1–2 feet above ear level.
Subwoofer / LFE (.1)
Front corner or side wall to maximize smooth low-frequency room coupling.

Frequently asked questions
What are the 6 channels in a 5.1 surround sound system?
A 5.1 system consists of: (1) Front Left, (2) Center (dialogue), (3) Front Right, (4) LFE / Subwoofer (low-frequency effects), (5) Surround Left, and (6) Surround Right.
Can a web browser play true discrete 5.1 surround sound?
Yes! Modern browsers (Chrome, Edge, Firefox) support discrete multichannel audio via the Web Audio API. If your operating system is configured for 6-channel output and connected via HDMI, DisplayPort, or a multichannel sound card, each speaker receives a dedicated discrete audio channel.
What happens if I test 5.1 on stereo speakers or headphones?
Our engine uses psychoacoustic HRTF binaural panning to simulate 3D room placement. Surround channels are filtered to mimic the way human ears process sound arriving from behind and to the sides.
Why are my rear surround speakers silent during the test?
Ensure Windows/macOS is configured for "5.1 Surround" rather than "Stereo". On Windows: Win + R → type "mmsys.cpl" → Select playback device → Configure → Choose 5.1 Surround.
