1. Audio Waveforms

When you open Audio Editor in VideoProc Vlogger, the first thing that gets into your sight is the waveforms in different audio channels. And the number of channels depends on the audio file. Most music files are stereo with 2 waveforms, while some movies containing surround sound have 6 waveforms.

The entire audio is selected by default. You can drag the mouse and choose a portion of the waveform, and you'll see the unselected segments in blue and the selected one in green. Only the selected part can be edited with options in the toolbar. Meanwhile, you can delete, copy, and paste the selected audio with keyboard shortcuts.

On the left side of the waveform, you can drag the slider to adjust the volume of a single channel, or click the square icon next to it to lock a channel when you don't want to apply changes to it.
