192k is a turning point. Below 192K, the sound quality is relatively damaged, especially the high-frequency part above 16Khz will be cut off.<\/p>\n

In a nutshell, mp3s above 192k can no longer be listened to with CD sound quality on ordinary home devices, except for Golden Ears and Hifi devices. Of course, these data are not 100% reliable. There are always people on the internet sharing fake mp3 above 192K. In fact, they are converting low bitrate music to high bitrate through software, but the sound quality will not improve. be improved. Windows Media Player compresses it. The resulting mp3 is absolutely wonderful, no matter how high the compressed bitrate is, it will cut perfectly around 16K.<\/p>\n
Some time ago, a colleague came across a very troubled client. The mess was said to have been caused by the client asking him to provide song files larger than 100MB-200MB in size. And my colleagues don’t know much about audio formats, so they started endlessly fumbling about FLAC, WAV and audio size. In the end, the colleague did not explain to the client what was going on.<\/p>\n
After that, other things happened that made me feel that in the music industry there are too many practitioners around me who have an extremely poor understanding of music and even lack some basic knowledge related to music. I don’t even have the idea to understand, which makes me very sad. It seems that music has only one merchandise attribute, and our practitioners only need to organize the shelves, encode various merchandise, and use the big data of users’ purchase records to recommend merchandise to users, no matter why to users. they like this. features that these products have, and use cold data to provide users with various services.<\/p>\n
Therefore, I think it is necessary to write something. I don’t expect practitioners to become people who really love music. I just hope that even if you still think of “her” as a commodity, you can first figure out what you’re selling. and what is..<\/p>\n
PS: The content of the first lesson is about media files. Since the relevant content involves a lot of technical stuff, it seems a bit boring, but if you read it carefully, you will find that it is actually very easy to understand, but this basic knowledge can be very helpful.<\/p>\n
Bit Rate, Sample Rate, Lossless, MP3, FLAC, APE, 320kb, 192kb, 128kb, 44.1khz, CBR, VBR. Does this bunch of various names make you both familiar and unknown?<\/p>\n
The higher the bitrate, the better the sound quality. Lossless music is the highest sound quality, right? So, let’s start with the sound collection.<\/p>\n
\u3010Audio composition\u3011<\/p>\n
Nowadays, when we talk about audio, everything is digital audio. Digital audio consists of three parts: sample rate, sample precision, and number of sound channels.<\/p>\n
Sample Rate: Both the sample rate, which refers to the number of samples per second when recording the sound, expressed in Hertz (Hz).<\/p>\n
Sampling Precision: Refers to the dynamic range of the recorded sound, measured in bits (Bit).<\/p>\n","protected":false},"excerpt":{"rendered":"
