Directly above the picture, foobar2000, look at the file properties, this is lossless music, look at stereo 2 channels:

This is 6-channel dts music converted from Jingting in Qian Qian to wav, which is listened to on dts5. 1 train. You can hear the positioning of different speakers, and you can hear the birds flying around in the music:

This is really practical, but it is still impossible to identify whether it is a real 5. 1 channel, and the sense of positioning is still good. Because stereo (2 channels) may be converted to dts5. 1, other channels may be repeated, so there is no sense of positioning.

Generally speaking, two-channel stereo can hear the difference between left and right, and dts5. 1 can hear the difference between front, back, left and right.
