237 Review answers 1 As counterintuitive as it seems, you face away from the sound-absorbing material.
The microphone picks up sound from the direction it’s facing. The absorbing material
minimizes the reflections the microphone picks up.
2 The microphone is probably too far from your subject, and you’re in a room with
reflective surfaces such as flat walls and an uncarpeted floor.
3 Drag an audio crossfade transition (Constant Power or Constant Gain) to the
beginning of the clip. Or use the volume level graph in the Timeline clip display
with two keyframes, dragging the first keyframe to the first frame and dragging that
keyframe to the bottom of the clip. Or use the Volume audio effect and two keyframes
to fade up the audio. Use interpolation controls to smooth what would otherwise be a
straight-line fade-in.
4 Raising the gain or volume increases the amplitude of the waveform. Normalizing the
audio examines it for peak values and allows you to adjust gain based on the peaks.
5 You use these cuts either to ease into a clip such as a sound bite or to let it fade out.
A J-cut starts audio under the preceding video (which also has associated audio or a
narration) and then fades up as you transition or cut to the video portion of that clip.
An L-cut fades audio under the next clip as a way to ease out of that audio/video clip.
6 Use keyframes to silence that portion of the audio. Then add part of the original
audio to another audio track and fade that up to fill the audio gap you created in the
original clip.
