It doesn't matter, just pretend I'm verbose and describe the method of opening it again.
I installed Alfred on your computer. Oh, just press Alt+SPACE together to open the input field for quick search ~ Is it thoughtful of my husband ~
So this time, we are dealing with an MP4 video.
Of course, Audition is a professional audio processing software, and the video is not chaotic. Next steps:
So, did you see the audio extracted from it?
Does the ripple of audio look very irregular? Is it obsessive-compulsive disorder? Is it all kinds of itching deep inside?
Don't worry, there are more chickens to catch. Let's listen to this audio now.
Do you feel that the people in the audio are big and small, strong and weak, and there are some noises?
Obviously, this is not the sound produced by professional recording environment and recording equipment. Forgive them.
Then you can gain a sense of accomplishment. Now let's roll up our sleeves and get to work.
Before that, we need to be clear about our goals and what we want to achieve:
Why noise reduction?
Because there is noise in the human voice, if the noise is a single piece, just delete it directly. But often the noise is accompanied by your recording from beginning to end. It is difficult for us to debug voiceprints by hand. Fortunately, audio processing software provides such tools.
The mechanism of noise reduction is subtraction. The software can't tell which ones are sounds and which ones are noises, so you have to tell the software which ones are noises, and then the software will help us subtract the noise part from the recording, so the rest is the sound part we want.
So, if you tell the software, what's the noise? Here is a recording trick, that is, after we record the human voice, we should deliberately record a noise continuously. In this way, we can take this noise to the software for sampling, and we tell the software that this audio is noise. According to the characteristics of this noise, remove this sound from the recording!
Of course, when recording, try to record in a quiet room. ...
Having said that, let's look directly at how the audition works.
In this way, we finished the noise reduction!
Be sure to reduce noise before dealing with human voice. Otherwise, the noise will be amplified to the same degree as the human voice, and then GG ~
In fact, it's relatively simple to deal with human voice, even if it can be adjusted manually, but if the software can be adjusted faster and better, why bother yourself ~ We have to practice golden ears ~
Let's see, as a result of application, are all voiceprints basically a stable amplitude?
This has achieved the effect we want! Is it simple?
Just drag it in, which is the red part in the picture.
The length of background music can't be adjusted casually. Because, you have to make people sound coherent.
Obviously, our background sound is longer than our voice, so we must edit it.
Editing background sound is a technical job, and you have to have a certain sense of music.
Of course, I won't let you practice for a few years before you finish your work. The following is the artifact provided by the audition.
At this time, we have to deal with the size of human voice and background sound.
We can't let the background music drown out our voices ~
The adjustment place is in the red box, and you can adjust it freely according to your inner feelings ~
To what extent? That is, you will feel that the human voice will not be disturbed by the background sound, and you can concentrate on listening to the content of the human voice. This feeling is enough.
We also have a very important operation, guess ~
Dangdang, congratulations, you guessed wrong, of course, it is not simply to save it as a local file ~
We need to export documents according to international/national export standards.
Haha, these meet the standard of audio.
Is the voiceprint of audio a lot slimmer ~
To the last step, what we just operated was lossless wav format. Now, in order to facilitate storage and transmission, we need to slim down the audio files. The more popular format is of course mp3 ~
Wow ~ it's finally finished ~ it's over ~
A * * * takes 2 hours and 33 minutes ~
I hope my lovely wife can see it ~
If you don't understand anything, feel free to ask me ~ I'm right by your side, haha ~
Good night, dear.
