There are many similarities between audio editing and video editing , For example, add clips or tracks on the timeline panel 、 Change view size 、 Use a razor tool to split and so on . You can unlink audio and video , To modify the audio clip separately . By default , The sequence of the timeline panel includes 3 A standard audio track and a main track . Main channel （ blend ） Soundtrack , Used to control the synthetic output of all audio tracks in the sequence .

Audio track type

5.1 Track... Track

5.1 The track contains 3 Front audio channel （ Left voice way 、 Middle channel 、 Right channel ）、 Two rear or surround audio channels （ Left and right channels ） Low frequency effect leading to SUBWOOFER SPEAKER (LFE) Audio Channel . stay 5.1 Only channels and tracks can contain 5.1 Audio material .

Adaptive track

Adaptive tracks can only contain mono 、 Stereo and adaptive material .

Audio Editor

There are many similarities between audio editing and video editing , For example, add tracks on the timeline panel 、 Scale clip waveform 、 Use the razor tool to split clips and so on , You can also unlink audio and video , To modify the audio object separately .

（1） Add track

Execute menu ： Sequence / Add track . perhaps , Right click on the timeline panel and select “ Add track ”, perhaps , Drag the existing audio clip to the next line of the main channel .

Orbital acoustic imager ： Set based on the whole audio track “ Balance ” Keyframes .

（2） Audio gain adjustment

Audio gain refers to the output current to audio 、 Increase degree of power, etc , The unit is decibels （dB）. Audio gain is often used to restore the original audio material to the normal volume .

It can be tuned for a single audio clip , You can also tune for the whole track , This requires different methods and panels .

Right click on the audio clip , choice “ Audio gain ”, Or directly drag the line in the timeline panel clip up and down （ Different from the previous method , This is an audio effect ）.

On the audio instrument panel , lower than -10dB, Low volume ; exceed 0dB, Easy to cause explosion point （ The thick red line on the audio instrument panel indicates that the audio clip has a burst point ）. Normal audio gain at -6dB about . Therefore, the amplitude should be adjusted according to the peak value .

Using audio gain is just one way to adjust the volume , You can also use the audio clip mixer or track mixer . perhaps , Drag and drop directly on the line inside the audio clip in the timeline panel .

The audio clip mixer is used to adjust the left and right balance of the current audio clip on the track 、 Volume level and mute setting 、 Solo, etc .

Before adjusting using the audio clip mixer , On the left side of the timeline panel “ Show keys ” Button , choice “ Clip keys ”（ Default ）, For intuitive observation .

After the write key function is turned on , Manually adjust the volume slider while playing audio , When you stop playing, you can automatically create keys . You can also write keyframes for left-right balance , Need to be in the effect control panel “ Acoustic imager / Balance ” To observe . Tips ： stay “ Preferences / Audio / Automatic keyframe optimization ” in , Can increase the “ Minimum time ”, To prevent too many keyframes .

The track mixer panel controls the whole track .

3、 Add audio effects

Add special effects to audio objects , Such as fade in and fade out 、 Swing effect and audio effect of the system .

（1） Audio transition

The method of keyframing audio clips is the same as that of video clips . After adding keyframes, pull the line directly , Or the volume in the audio effect in the effect control panel / Level adjustment , You can easily achieve the fade in and fade out effect .

Tips ： Mute yes -∞dB.

The audio transition in the audio effect provides 3 Cross dilution transition . among , Constant power is equivalent to the crossover in the video transition , Is the default audio transition effect .

（2） Use audio effects

“ Audio effects ” In the folder 40 Multiple sound effects . In the effects control panel, all sound effects have bypass Options , Equivalent to special effect switch . and Acoustic imager Medium Balance , The sound of stereo channel can be transformed into the effect of switching back and forth between left and right channels .

Analyze several common effects ：

Multifunctional delay 、 Analog delay, etc ： It is often used to produce echo effect .

Indoor reverberation ： It is often used to simulate the reverberation effect in different environments , Such as hall reverberation , There is a sense of presence in the room .

Noise reduction 、 Eliminate buzzing 、 Adaptive noise reduction, etc ： Commonly used to remove noise from audio .
