How many KB is the best sound quality for mp3? Part 2

Mp3 Quality
Mp3 Quality

The most widely used decoder chip on the market today is, of course, the well-known STMP3410 from Sigmatel.

Mp3 Quality

Whenever you disassemble your mp3, you will find that your mp3 uses STMP3410 decoder chip. The decoder chip is highly integrated and has concentrated functions. It is easy for manufacturers to develop or add new features such as letter display and electronic dictionary. The relative cost is relatively low. It ranges from high-end brands like Samsung, MSC, and Giving to some misc and even names All brands that cannot be called are used, the sound quality is quite satisfactory, the low frequency is a bit weak, the voices and the musical instruments are not bad. Of course, the sound quality performance of mp3 using STMP3410 decoder chip is not the same and sometimes even very different. The reason lies in the internal circuit design of the mp3, the soldering process, the material of the circuit board, and the difference between various manufacturers, especially There is a big difference between the big manufacturers and some non-brand manufacturers. These are also the key factors that affect the work of the decoding chip and the sound quality output. Take two high-end machines that also use the STMP3410 chip and compare the unbranded machines to understand. Therefore, due to many factors within the mp3, the price of the mp3 that also uses the STMP3410 chip varies.
What’s more, there are some unscrupulous manufacturers on the market who use discarded or recycled second-hand FLASH chips, along with inferior circuit design, quickly made an mp3 and sold it to the market. Usually the price of this kind of mp3 is very low, and the 128m memory is sometimes cheaper than the same capacity U disk, and the sound quality can be described as rubbish. Come to think of it, we all know that manufacturers have to survive on such a small profit, unless there is something in the mp3, who will make it for free? So when you come across this kind of mp3, you should pay more attention, no matter how good the sound quality is, it can’t be better. Other decoder chips such as Sigmatel’s STMP1342, Telechip’s TCC730, Samsung’s S3C2410, etc. will not be discussed in detail due to their similar performance.
With the deepening of the market, some powerful manufacturers are also constantly exploring to dedicate the best sound quality to consumers. JNC’s new SSF-800 machine uses the SIGMATEL3420 chip, and the sound quality is very impressive. The next new mp3 just released by iriver uses the most powerful SIGMATEL3520, which is worth waiting for. The good news is that the Meizu me released by the national brand Meizu also uses the SIGMATEL3520 decoder chip, which is the first time for a national brand. It appears that the national brand is slowly creeping into the ranks of premium sound effects as well.
Second, the quality of music playback files The
decoding chip is important, but in order to enjoy high-quality music, the factor that affects the sound source itself is very large. In turn, the quality of the audio source depends on the music file format and compression ratio. Nowadays, the most popular music formats are of course mp3 and wma, almost all mp3 players support these two formats. MP3 should be considered as the most lossy compressed digital audio format currently used by users. The mp3 files that we usually listen to have a bit compression rate of 128kbps, the compression rate is about 1:10, and the file size is usually only 4m. to a more balanced position. The compression rate of the songs we download from the Internet is usually relatively low, often only 96kbps or even less, and the effect is not very ideal. This is a practice where websites deliberately lower the compression rate due to download speed and copyright issues. To enjoy real sound quality, the best way is to find a better quality CD disc and compress it yourself. Generally speaking, the sound quality of mp3 files with a compression ratio of 192 kbps is relatively good. When played with a good mp3 player, the effect is very similar to md. If compressed to 320 kbps, the sound quality is very similar. to the CD player It’s hard to tell the difference. (Of course, those with golden ears are excluded)

Four Factors That Determine MP3 Sound Quality

Mp3 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.

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)

MP3 Bitrate
MP3 Bitrate

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?

MP3 Bitrate
MP3 Bitrate

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.

What is Hi-Res sound and how it differs from normal audio

In recent times, many manufacturers of audio products have begun to add Hi-Res products to their catalogs, an acronym that comes from the English «High-Resolution», and indicates that the device is ready to play the audio with it quality that has been recorded, which is synonymous with maximum fidelity. But what features does Hi-Res sound have and why is it different from normal audio?

 

What is the Hi-Res sound?

The sound that is recorded in the studios – whether music, cinema, dubbing or whatever – is raw audio, without compression, and the recording is done in an analog way, because as you know the sound is formed by waves . Logically, for this audio to be heard on our televisions, smartphones, consoles and others, it is necessary to convert it to digital, and for that to be possible we must first be able to measure the waves so that they can then be recreated in the device that is going To emit the sound.

To measure these waves, a series of periodic samples are taken, and this is what is called the sampling rate. This sampling rate cannot be infinitely, logically, but the higher, the greater the fidelity of the audio we are converting to digital, and that is why we set some scales or minimums for each quality.

Thus, for example, the audio sampling frequency of a normal music CD is 44.1 Khz, which means 44,100 samples are taken from the waves per second. For Hi-Res sound, the standard is set at 96 Khz, or 96,000 wave samples per second, so you will be collecting many more nuances of the original sound, being much more faithful to it.

Hi-Res sampling rate comparison

 

As for the sound we reproduce in our equipment, there is another factor to consider: compression.

The normal sound, when recorded, is done in a pure format and without compressing anything. But this type of sound has the disadvantage that the size of the files is very large, so it becomes complicated to store them in multimedia playback devices. This is especially true if we think that most users use our mobile or tablet to play audio files.

To reduce the size of these files, sound file compressors were created, such as the MP3 format, which try to give a more or less authentic approximation to the original sound source, but with a considerably smaller file size. For example, if an MP3 file with a compression of 256 kbps has a size of about 3 megabytes, that same file, without compressing, can have more than 30 MB.

What does Hi-Res sound bring to normal audio?

When the sound is compressed, or as we have seen when it is converted from analog to digital, many audio frequencies are lost, among which are many subtle details of the sound, which give it much more body. As we explained before, Hi-Res sound tries to get closer to the original audio, setting its quality standard with a sampling frequency and bit depth much higher than normal audio.

Currently, the Hi-Res sound formats that exist are: WAV, FLAC, ALAC, DSD and MQA. Of all of them, probably the best known for PC are the WAV format and the FLAC. The WAV format is usually used to record the original audios, but their files take up a lot of space because it is still uncompressed audio. The FLAC format is a type of compression that also falls within the Hi-Res sound quality and sufficiently compresses the sound source so that the loss of quality is absolutely minimized.

What do we need to hear Hi-Res sound?

Since the audio we will have in hand has certain special characteristics in terms of frequencies and formats, we will need an audio player that is capable of dealing with these compression formats, since not all players are capable of doing so. However, virtually any modern PC sound card, including those integrated into the boards, as well as many smartphones on the market (not televisions), are already capable of handling Hi-Res sound. According to the Japanese Audio Society, who created the Hi-Res audio standard, the DAC (the analog-to-digital converter) must be able to process audio at 96 KHz and 24 bit.

What is the HI RES AUDIO

Everything you wanted to know about Hi-res and didn’t dare to ask.

With the Walkman’s return to our lives, we saw that a trend that had sounded since 2012 made another call to consumers: Hi-Res Audio. High-definition sound will be one of the striking themes that, like UHD on television, could change the demands that consumers want in their products.

However, many only know this type of audio by some yellow sticker attached to a device. But what is Hi-res Audio? Is it as good as they say? Here we tell you.

To clean your ears well

Since the arrival of digital formats, audio recordings have maintained a quality standard whose measurement point is an audio CD. The quality of this format is 16-bit / 44.1 kHz.

To understand these two measurements you have to understand how music is digitized from similar sources. The scanning programs convert the sound waves into bits, and for that they must take a limited number of audio samples and convert them into information. The second number (44.1 kHz) indicates the number of samples per second that are taken to make the conversion, and is called the sampling rate. The first number (16-bit) indicates how much information is captured from each sample. Simplifying a bit, the more bits an audio file has, the more information it receives, the more faithful it is to the original analogue and the better quality it has.

However, files of this quality are very heavy for a computer and other devices that served as audio players from past decades, so .MP3 was born as a format that compresses information and offers sufficient audio quality for most of consumers.

But with the advent of new technologies, and the revival of some old ones, consumers began to worry again about audio. Now we buy the soundbar because we want to hear our Spotify stream perfectly, or we look for the best home theater to feel like in a movie theater. And that we have created those needs are driving new formats (which have been around for a long time, but were recently popularized) But, to validate these new formats, a standard was needed, and thus the definition of Hi-res Audio was born:

“Audio without loss of quality that is capable of reproducing the total sound range of recordings that have been finalized from better quality music sources than a CD.”

As WhatHiFi reports, this definition was given by the Digital Entertainment Group (DEG) together with the Consumer Electronics Association (CEA) and the Recording Academy. This group was joined by companies such as Sony Music Entertainment and Universal Music Group. And by the way, they defined the formats of high resolution audio sources:

MQ-A: That comes from an analog source.

MQ-P: That comes from a PCM master source (48kHz / 20-bit or greater, such as 96/24 or 192/24)

MQ-D: That comes from a DSD / DSF master source, which are formats used in studio audio editing.

MQ-C: That comes from a CD.

And under a more popular definition, high-resolution audio is the one that can make you feel your hair bristling when the ‘Stairway to Heaven’ solo sounds, or the solo La rebellion ’piano solo by Joe Arroyo. A feeling that is not achieved when the format is not able to reproduce the entire sound spectrum that moves our guts.

So if you want to have songs of good quality, the first thing that should be fixed is that the store that sells them offers Hi-Res formats (the Sony music store, HD Tracks, PonoMusic, Gimell, etc …), and usually what they will download will be a file type .FLAC, .DSD, .AIFF, .WAV or .ALAC. In terms of image, they would be like the RAW of the audio. These types of files take up much (much) more space than a .MP3, so be prepared in case the flies.

Great sound requires great machinery

In order not to lose money or effort, it is necessary to have a good team that is capable of reproducing high quality audio. At home we must have a sound system with high quality speakers. Some cell phones such as the LG G3, the Sony Xperia Z3 and the Samsung Galaxy Note 4 have the power to play Hi-Res audio without buying headphone amplifiers. Other cell phones such as the iPhone 6 need an amplifier to give the headphones enough power to reproduce the high resolution audio. And, precisely, to be able to hear these files it is necessary that the player and the speakers that emit the sound are of high quality and can reproduce the entire spectrum.
