Today we will talk about the difference between mobile phone recording and sound card plus microphone recording.
Many friends are confused. I know that mobile phones can also record. Why do I have to spend a lot of money on sound cards and microphones that I haven't bought? Actually I don't know how big the difference is. I will do an experiment today. Warm reminder, please bring headphones to listen to this program, and choose the Himalayan sound quality as high-definition sound quality or ultra-clear sound quality.
Open it up.
First, I will show you the dry sound recorded by several different devices. I try to ensure that the distance between my mouth and the recording device is the same. Later, I will adjust their volume to roughly the same.
I think friends with sharp ears should be able to hear a little difference. What is the rustling you hear? That's right, it is background noise, or environmental noise, which can be improved only by sound insulation of the room. This is a point of knowledge. Use a small book to copy it.
Usually dry sound cannot be used directly, unless you are in a recording studio or your environment is very low noise.
Let's reduce the noise on them and listen again.
Well, today’s experiment ends here. Actually, the difference between the sound of 100 yuan, the sound of 500 yuan, and the sound of 2000 yuan is not very big, so you don’t need to spend such a big price, because the sound quality is improved a little bit for ordinary listeners. I can't hear it~
From the sense of hearing, the sound recorded by the mobile phone is thin, stray, not concentrated, and there is too much air (excessive high frequency). Although we can use the way of adjusting eq to balance the frequency in the later stage, we can achieve the fake and the real, but it is a bit complicated, let's talk about it next time~
Of course, each microphone will present a different sound characteristic, choose one you like, usually to restore the original sound is the best.
So why do most audiobooks need equipment to test sound?
Isn't it because I want to raise the threshold of the audition, I think it is very possible.
However, more reasons I think are because the sound quality recorded by the mobile phones of various manufacturers is uneven (especially the mobile phones of poor quality), and the post-processing is also more troublesome. Moreover, the mobile phone records usually have some If the format is lost, and some post-processing is required, the sound quality will be lost again, resulting in failure to meet the broadcast standard.
