I'm not dog licking

Chapter 115

Qin Cai said to the ministers:
Today I will teach you the knowledge of text editing and audio editing.

After class, we set up two yamen, one responsible for copy editing.

A job in charge of audio editing.

I must lead everyone to develop our country into a technological country that is free from backwardness.

The ministers were all excited when they heard the words.

One by one kept shouting:
The ministers and others respectfully listen to His Majesty's instruction.

Qin Cai nodded in satisfaction and said:

Qin Cai took a sip of water and said:

Next, let's learn audio knowledge.

First: During audio playback, j stands for backward, ; stands for forward.

Second: [represents setting the start point,] represents setting the end point.

Third: Under multi-track, regardless of the number of tracks, you can use the alt key to increase the keyboard to jump to the main interface, and then ctl to find the place to adjust the volume to adjust the appropriate volume.

Fourth: Record a multitrack session consisting of three tracks,

First, save the current project by pressing the alt key and pressing the s key before starting the recording.
This way there will be six recording tracks. If you don’t need so many tracks, then find the track you want to delete.

Then shift plus d to delete, and so on,
After track [-] is inserted with background music, switch to track [-], and then shift + r key to activate the recording state of this track,
Then you can start recording, the button to start recording is shift plus space,
After the recording stops, remember to shift and press the r key to turn off the recording status of track [-].
Then switch to track [-], click the space to start playing, play the place where you want to insert the sound effect, set the starting point,

Then you can insert sound effects like inserting background music,
Finally, in the Edit menu, click Mix Record as a New File and it’s done.

Note two points here,

The first point is that when you don’t need to record, you don’t need to activate the recording status of this track. If you need to activate the recording and this track completes the recording task, you must remember to turn off the recording status.
The second point is that the selection view is very easy to use. The Alt key increases the six keys on the keyboard to activate the selection view, and then press the key to switch, and you can customize the beginning and end of the current audio.

Fifth: Reverb effect

Insert an audio under the single track, expand the menu with the Alt key, find the reverb in the effect, open it, enter the room reverb inside,

Then switch between the four and six keys of the small keyboard, and there is a zero client behind the parameters inside, which can be opened and modified by a single computer.

Parameters are: room size, attenuation, dry sound, loss of sound, high frequency cut, etc.,
However, the stereo width, early reflections, slow reflections, and attenuation in the parameters can only be heard with audio equipment such as monitor headphones. The low-frequency cutout cannot be turned on because the mouse focus is difficult to focus.

Sixth: the use of mixed paste.

Under the single track interface, for example, importing a song,

First set the start point and end point of a certain part of the song,

Then copy, followed by simultaneous pressing Who Fut plus Paste to activate the mix-paste menu,
Then under this menu, you can press the button and the cursor key to browse,
There are settings for setting the volume of the left and right channels, as well as setting the paste mode and the number of loop pastes, and setting the cross-fade time.

The paste mode mainly includes, repeat paste, similar to the effect of a duet, and insert paste, which directly increases the original audio,

There is also replace paste, which directly replaces the content of the part where the audio paste enters.

As for the number of pasting cycles, as the name suggests, it means how many times it needs to be pasted.

Crossfade is to set a fade time in a certain part of the audio that gradually increases or decreases to avoid being too abrupt.

Please note that when you have copied the selected part of the audio, you can also copy the selected part directly as a new file.

Seventh: the use of the clipboard,
The audio editing software comes with six clipboards,
For example, if you want to copy an imported audio or sound effect to clipboard [-],
Then you are willing to press the key to increase the number two of the keyboard, first locate the second clipboard, and then copy it.
When you want to paste the content of this clipboard into another new audio,
You can choose from the mix and paste menu.

Eighth: The use of amplitude effects.

The first is the amplitude statistics. The main statistics are whether the imported audio is overloaded. If it is overloaded, which segment is overloaded, and remember to select it as a sine wave, because except for professional recording studios, it cannot meet the requirements of square waves.

The main reference data to determine whether there is overload is that the maximum sampling value cannot exceed 32767,

The minimum sample value cannot exceed -32768,

Amplitude peaks cannot exceed 0,

The maximum and minimum rms values ​​refer to the highest and lowest volume of the audio,

The hotkey for amplitude statistics is, alt key plus u,

After talking about the amplitude statistics, let's look at the amplitude fader.

There are mainly two tabs: Brightness and Gradient.
Brightness is to set the volume, and gradient is to set the volume change from high to low. In fact, the gradient effect is similar to the cross-fade effect, but the gradient effect cannot accurately set the fade time.

Ninth: Make a cross-fade effect for the opening and ending clips of the white dragon horse, and reduce the overall volume in the middle by [-] decibels.

First import the white dragon horse,
Then select all and enter the bright tab in the amplitude fade process, reduce the volume by [-] decibels, confirm,

Then select the opening segment and increase it by [-] decibels,

Then copy the opening clip, and click Undo, so that the entire White Dragon Horse will still return to the state that was reduced by [-] decibels overall.
Then use mix paste, select mix repeat paste and cross fade, set the cross fade time in milliseconds, the time is a little more than milliseconds, so the effect is better, sure,
It's the same way with the ending sequence, done.

Tenth: the use of normalization effects and hard limit effects,
The normalization effect is mainly used to prevent audio overload, or an effect device used to make the audio conform to the standard.

It can standardize the amplitude peak within zero, such as 0.3,

The hard limit effect is also used to prevent audio overload, but it can be set and adjusted more comprehensively.
There are four parameter items in it, in order,
The first one is to set the upper line of the peak amplitude, the second one is to set the increase of the maximum rms value, and the last two are to set the effective time and end time of the effector.
