Mixing Audio
Adjusting gain
You can adjust the gain , or volume, of a single clip. This is useful for balancing the gain levels
of several clips or when a clip’s audio signal is too high or too low. However, keep in mind
that if the gain in an audio clip was set too low when it was digitized, increasing the gain may
emphasize noise or introduce distortion. For best results, follow the standard practice of
making sure the gain level is correct at the time the audio clip is digitized.
For more control over gain, use the Compressor/Expander filter; see the topic
“Compressor/Expander” in online Help.
To adjust gain uniformly for a clip:
1
In the Timeline, select an audio clip and choose Clip > Audio > Gain.
2 Do one of the following:
•
Type a Gain value. A value above 100% amplifies the clip. A value below 100% attenuates
the clip, making it quieter.
•
Click Normalize to set an automatic gain value calculated by Premiere.
3
Click OK.
Fading and cross-fading
You can easily fade the audio track in or out. The red fader , also called a rubber band , allows
precise adjustment of the gain level at any point during the clip. You specify the point by
creating a
handle on the fader. A handle marks the beginning and ending of a fade, and you
can drag the handle up or down to change the fade level. All audio clips include two handles
that you can’t remove—one at the beginning of the clip, and another at the end. You can also
cross-fade two audio clips automatically so that one fades out as another fades in.
