The wonderful use of audio switcher function in Baofeng Video

Since the encoding of various video files is different and the production level is different, when playing video files, you will often encounter problems such as different pronunciation of left and right channels, unsynchronized sound and picture, and low volume. These problems can be solved by adjusting the "audio switcher" function of Baofeng Video.

*Switch left and right channels
　　When we play some VCDs, we often encounter bilingual videos. If you want to have only one channel sound, you usually click the "View → Options → Playback" option and move the slider in the "Equalization" option to one channel. This will block the sound of the other channel, but this is not perfect, because only one speaker can make sound at this time, which must be uncomfortable to watch movies. What if you can make both channels sound the same channel at the same time? You can use the following method to solve it. Click the "View → Options → Audio Switcher" option, check the "Enable built-in audio switching filter" and "Enable custom channel mapping" checkboxes respectively, set the "Speaker Configuration Box" to 2 "Input Channels", and then check all the front left and front right options as the same channel according to the channel where the sound is located. Finally, click the "Apply" button, and the left and right speakers will sound the same channel at the same time.

* Improve volume and sound quality
　　When playing videos with Baofeng Video Player, if the sound is low and muffled, and the volume cannot be increased even if the volume on the panel is adjusted to the maximum, we can solve it by the following method.
　　Open the "Audio Switcher" window according to the previous method, check the "Enable built-in audio switching filter" and "Enable custom channel mapping" checkboxes respectively, select "Speaker Configuration" as 2 "Input Channels", and then select all the checkboxes from "Front Left" to "Top and Back Right" in the box below. Channels 1 and 2, click the "Apply" button, and you will find that the volume has increased significantly, and the sound quality has become crisp and full of three-dimensional sense. It should be noted that after using this method to increase the volume, it is best to restore the original settings after playing the movie. Because some movies may conflict with such settings when playing, resulting in failure to play normally.

*Synchronize the sound with the picture
　　When playing video files, the sound and picture are out of sync, which is a problem we often encounter. Baofeng Video has provided a solution for this problem.
　　In the "Audio Switcher" window, check the "Enable built-in audio switching filter" and "Audio delay time (milliseconds)" options respectively, and then calculate the time value according to the time difference of the out-of-sync and enter it into the box. Negative values are delayed sound playback, and positive values are early sound playback. Finally, click the "Apply" button. In this way, the sound will be played in advance or delayed.
