(2) Hold down the left button and click on the material to drag in a certain audio track to display its waveform;

1. Drag the volume "signal" mark in the lower right corner of the audio block left or right;

2. Up and down the yellow volume envelope line on the audio block

3. You can also place keyframes on the volume envelope line and adjust the volume of the audio segments within the audio block individually by adjusting the keyframes.

4. Fade in and out. There are two small squares on the upper left and upper right of the audio block. Press and hold the small square and move it left or right to adjust the fade-in and fade-out effects of the beginning and end of the audio block through the length and shape of the line;

4. Adjust the blue sound image envelope on the audio block. If it is in the middle, there will be no left and right drift, which is equivalent to the sound being right in front;

5. Move the sound-image envelope to the top, and the sound will be on the left; move it to the bottom, and the sound will be on the right;

6. Put key frames on the sound and image envelope line, and then move the key frames to achieve the effect from left to right or from right to left.
