I don’t know if you have any problems with the background sound being loud but the characters speaking softly when playing movies using the player KMPLayer? Well, some netizens said it might be the quality of that film. In fact, what is the reason for such a problem? The editor of Huajun will first tell you about this problem and its specific solution. Users who want to know more can take a look at it.
Analysis of the problem of KMPLayer playing movies with loud background sound but low voice:
1. Solution: "Parameter Options Others" → "Parameter Options" → "Audio Processing" → "Resampling Output" → "Output Mode", then in the lower right part of the right window, set the default: input (original) equals output (Recommended)) modified to "2/0 Stereo".
Change the output mode to "2/0 Stereo"
After setting it up, when you play the relevant video again, you will find that the problem of "loud background sound but quiet speaking volume" no longer exists.
2. So what is the cause?
Under normal circumstances, since the surround sound system provided by Dolby Digital AC-3 5.1 consists of five full-range (3-20000Hz) channels plus a subwoofer (3-120Hz) channel, the center channel most of the time Responsible for replaying the character's dialogue.
The front main left/right channels are used to compensate for movements and other sounds outside the center of the screen or that cannot be seen from the screen, while the rear surround channels are responsible for the periphery and the entire background music. The subwoofer channel contains some additional bass information, making some scenes such as explosions, impact sounds, etc. better.
Since ordinary users' computers only have two channels, and KMPLayer, Baofengyingyin, etc. default to "input equals output", so the player can only simulate the front main left/right channel when playing videos, but cannot take into account the characters. The center channel of the dialogue (i.e. "voice") eventually caused the problem of extremely low voice.
