KMPlayer Play movie background sound big but small voice problem analysis:

1, the solution: "parameter options" → "parameter Options" → "Audio processing" → "resampling output" → "output mode", and then the right side of the window in the lower part of the default: input (original) equals output (recommended)) modified to "2/0 stereo."

Modify output mode to 2/0 stereo

Once you've set it up, when you play the related movie again, you'll see that the problem of "small background noise" doesn't exist anymore.

2, then what is the cause of it?

Typically, the surround sound system provided by Dolby Digital AC-3 5.1 consists of five full frequency domain (3-20000hz) channels plus a subwoofer (3-120hz) channel, and the central channel is responsible for replaying the characters ' dialogues most of the time.

The front main left/right channel is used to make up for actions and other sounds that are outside the center of the screen or not visible from the screen, and the rear surround channel is responsible for the external and entire background music. The subwoofer contains some extra bass information, which makes some scenes such as explosions and impact sounds better.

Because the average user's computer has only two channels, and KMPlayer, Storm audio and video, etc. the default is "input equals output", so the player can only simulate the front left/right channel when playing the movie, but can not take into account the character dialogue (that is, "voice") of the central channel, and finally caused a very small voice.
