Surround 5.1 low frequency speaker test

With this test you can explore, how your hi-fi device mixes the surround channels to the loudspeakers. Even if you haven't got the rear speakers and/or sub-woofer, the surround and LFE (Bass) channels might be mixed to the existing speakers. The mixing method depends on the type of your hi-fi device and the actual settings of your device.

The audio in this video is not properly downmixed. Just uploading 5.1 content to YouTube does yield a surround compatible downmix that can be decoded by a matrix decoding technology like Dolby Pro Logic or DTS Neo. YouTube instead will just send all left channels to Stereo L, all right channels to Stereo R and the center equally to Stereo L and R. LFE is sometimes mixed as the Center equally to Stereo L and R, but many times the LFE is discarded. It depends on the downmixer and the way it is configured.

The downmix or mixing method is not performed by the hi-fi devices but by the uploader or by YouTube. The upmixing from 2.0 to 5.1 is performed by the hi-fi devices but this will only work if the downmix is properly done. Otherwise you end up with just Stereo as most people experience.

It does work on my home theater only when played in the tv, going through the optical cable to the home theater

Youtube supports 5.1 audio, but only on smart tv's like Chromecast with Google TV

YouTube only supports 2 channel audio so don't use this video for testing out real 5.1 sets

이영상으로 테스트 해보지만 5.1 스피커 센터스피커에서는 소리가 나오지않습니다. 유튜브는 5.1로 나오지 않는것으로 압니다
