Four Factors That Determine MP3 Sound Quality

Mp3 Quality

Today’s mp3 market can be described as a hundred flowers in bloom, and the competition between the major manufacturers is splendid. In order to take the lead and gain the most market share, various manufacturers, especially those with strength, have their own unique tricks. In terms of appearance, mpio’s fl200 has won the award with its mini round cake design. unique pendant. The latest mp3 title, Truly’s mp379, also created the trend of big screen mp3, and Samsung also released its sports mp3 concept, which is absolutely stunning in the market. Some small manufacturers have also adopted imitation methods, making the market of all kinds of mp3 like a sky full of countless stars. Simple repeat, record and fm functions can also meet the needs of the market. Line-in, features, e-book reading, gaming, and colorful backlights are slowly creeping into the new mp3 design. However, the author believes that no matter how cool it looks and how perfect its functions are, the mp3 is used to enjoy music in the final analysis. An mp3 without good sound quality is at least not a qualified mp3. If you just go for looks and function (actually, we rarely use some functions), and ignore its sound quality performance, you will feel a bit like buying a scorpion.
A decoder chip inherent in mp3
The decoder chip used by the Mp3 itself is the key to its sound quality. The sound quality displayed by high quality decoder chips is unmatched by those of the poorest. Friends who have listened to the famous iriver series of mp3s will know that its sound quality characteristics are very obvious, the bass is strong and powerful, the vocals are restored to truth, the high-frequency field is wide, and the increase is enough, which is very pleasing to the ears. This series mp3 adopts Philips SAA7750, the most advanced decoder chip in the market, and its quality and performance are excellent. The major Korean manufacturer MPIPO (Dewei Technology) also uses this decoder chip. The reputation and market feedback of these two mp3 sound quality brands are very good, and they are highly praised by the industry and outside the industry. It proves that mp3 sound quality is better than md’s ace gun. Due to the relatively high cost of the chip and the control chip, it is rarely used except for some brands. The cost is high, and the price is of course expensive. This is also the threshold that restricts many mp3 lovers from enjoying the beautiful sound quality.

What is the difference between 128k and 320k music?

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 clearly explain to the customer what was going on.

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 provide users with various services with cold data.

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..

PS: The content of the first lesson is about media files. Since the relevant content involves a lot of technical issues, 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.Improve your skill well. Also expect more interesting content about records, musical styles, etc. which I will post soon.

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?

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.

【Audio composition】

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.

Sample Rate: Both the sample rate, which refers to the number of samples per second when recording the sound, expressed in Hertz (Hz).

Sampling Precision: Refers to the dynamic range of the recorded sound, measured in bits (Bit).

What is the recording bitrate (the appropriate mp3 bitrate range)

All music on the web is digital, so what does the “bitrate” or “kbps” you see when previewing or downloading mean? What is bit rate?

In its simplest terms, bitrate represents the amount of data a file produces per second.

For example, you might see something like “320 kbps.” Literally, that means 320 kilobits per second, or the amount of data that is produced.

How does bitrate affect music?
Common audio file formats are MP3, OGG Vorbis, or AAC, which can be called lossy compression, while others are lossless compression, such as FLAC or WAV, which basically retain all the audio information.

320k is the highest bitrate encoding of mp3, and the sound quality is generally considered to be the closest to CD format. If you listen to popular music, you can see that there is more music encoded in 196k. From the point of view of listening, the difference between 320k encoding and uncompressed encoding is negligible, but in theory, the bit rate of a common CD is 1411k, which is 4.5 times the bit rate highest of MP3.

There is a direct relationship between bit rate and sound quality, but reasonable compression does not degrade listening.

Since MP3s are lossy files, meaning some of the audio is lost due to compression, why don’t the ears seem to change the sound? This involves psychoacoustics, a fringe discipline that studies the relationship between sound and the hearing it provokes. Psychoacoustics refers to “the way the human brain interprets sound.” Compressed audio is the use of powerful algorithms to convert audio messages that we cannot hear. remote.

So even though the bitrate of a lossy file like MP3 is much lower than that of a lossless file, it doesn’t sound like that. Even with just 320kbps MP3, the listening experience is not 4.5 times worse than music on CD.

Of course, the compression is not unlimited, when the bit rate drops below 128kbps, the sound quality will be degraded, and the lower it is, the more obvious it will be. On the contrary, the higher the bitrate, the higher the quality of the music.

Mp3 ape flac What is the difference between the three music formats?

When we often download songs, we want to download some of the best sound quality, and we are also confused about which sound quality is the best.

If you ask the friends around you, they will definitely all say that you want to download lossless files, but how good is the sound quality of lossless files?

First of all, the first impression is that the volume of lossless files is obviously different from normal MP3 files. Normally, the size of normal MP3 music file is only 2-5M, but the volume of lossless APE files of the same version is about 30M, a difference of 10M times more.

In the case of the same playback time, why is there such a big volume difference?

Here to talk about a term – bitrate It is a data factor that determines whether the quality of a song file is good or bad, bitrate refers to the number of bits transmitted per second (bit). The unit is bps (bits per second). The higher the bit rate, the higher the data transmission speed. The bit rate in sound refers to the amount of binary data per unit of time after converting an analog sound signal (a signal with sound properties such as amplitude and frequency) into a digital sound signal (i.e., a binary signal such as 010101 stored on a computer’s hard drive) is an indirect measure of audio quality. The principle of bit rate (bit rate) in video is the same as in sound, which refers to the amount of binary data per unit of time after the analog signal is converted to a digital signal.

Bitrate Property for Lossless Files

Bitrate Properties for High Quality MP3

The bit rate of MP3 files with ordinary sound quality is generally 128 kbps, the bit rate of high-quality MP3 files is generally 320 kbps, and the bit rate of lossless files is generally 960 kbps. kbps or even more. The difference in bit rate can be understood as the vibration frequency of the sound decoded by the decoder at the same time. The higher the bit rate, the higher the vibration frequency and the better the corresponding sound. Good timbre means that the restoration of sound details is relatively complete, that is, the sound quality is good. However, this is also the reason for the large size of the lossless files.
