Surround Sound Test
Click each channel node or run Auto Test. Honest note: your browser plays this as stereo — see the limits below.

Start at a low volume, especially with headphones and low bass tones, then raise it slowly.

How to use
- 1
Pick a layout
Choose 2.0, 5.1, or 7.1. Channels that do not exist in the layout are hidden — 2.0 keeps only L and R.
- 2
Test channels one by one or automatically
Click a node to play a short tone placed at that position, or start Auto Test to walk through all active channels in order. Each channel announces itself in the status line.

What to expect
Front channels should sit clearly left/center/right. Surround and rear channels are simulated — you will hear direction from only two speakers if your system is stereo.
How it works & limits
Browsers deliver at most a stereo signal to the operating system. This tool therefore simulates the 5.1/7.1 layout: each channel gets a stereo pan position and a slightly different tone, so your two speakers (or soundbar) hint at direction. It is a fun and useful wiring check — but it is NOT a Dolby/DTS multichannel bitstream, and this site makes no Atmos claims.
True 5.1/7.1 playback needs the whole chain to cooperate: a multichannel source, an OS configured for 5.1/7.1 output, a driver or AVR that decodes it, and wired surround speakers. If your system is really 5.1/7.1-capable, this page still reaches it as stereo — use your receiver’s built-in channel test for real per-channel checks.
FAQ
Is this a real 5.1 or 7.1 signal?
No. It is a stereo simulation through browser panning. Real multichannel output requires system and hardware support; this page checks your stereo chain and gives a sense of layout.
Why can I not hear the rear channels behind me?
Because nothing is playing behind you — two front speakers cannot place sound behind your head. Rear/surround nodes here are panned wide and lowered slightly, which is the limit of the illusion.
Does it support Dolby Atmos?
No, and be wary of any browser page claiming Atmos playback. Atmos requires object-based rendering on supported hardware.
Can I use this with my AV receiver?
You can, but the receiver will receive plain stereo. For true per-channel checks, use your receiver’s own test-tone menu — it exercises the actual amplifier outputs and wired speakers.
Why does the subwoofer channel sound like a low rumble?
The LFE node plays a low sine (around 60 Hz). On systems without a sub it may be faint or absent — that is your system, not a bug.
