The relationship between MP3 frequency, bit rate, bit rate and sound quality.

mp3 encoding

Each song is ripped from a CD, converted to a WAV file, and then converted to MP3 using encoding software.

mp3 encoding lossy compression

So it should be a sample rate of 44100 KHz. Unless yours isn’t a song, but you record it as a WAV file and choose another sample rate when recording.
The main factor that affects the sound quality of MP3 is the bit rate. Now the best is 320K CBR (fixed bit rate) and VBR (variable bit rate), VBR files are a bit smaller than CBR. 192K VBR is the most popular on the Internet, which can meet the requirements of sound quality and file size at the same time, but I usually use CD to rip tracks or download APE (lossless compression, which can be restored to WAV file) and then convert it to 320K VBR.
Final reminder: MP3 transcoding is distorted and this distortion cannot be reversed. That is, if you convert MP3 to WAV sound quality, the file size increases dozen times, but the sound quality remains the same as MP3 sound quality.
If you want to hear low distortion, it’s better to listen to a CD or download APE.
First of all, sound quality is a very subjective thing!
It is often said that the sound quality is good, one refers to the good degree of reproduction, that is, the smaller the difference with the recording, the better; the other refers to the pleasant sound, which is good. As for mp3, mp3 is a compressed format, the higher the bitrate, the less compression and less loss of detail, that is, the higher the bitrate, the closer to the original sound. But sound quality is also related to your output device, such as a good mp3 player and a good pair of headphones, all of which will help your listening quality!
So if you want to improve sound quality, you can also start from the above perspectives and not overemphasize any one of them. When you have higher requirements for sound quality, you can give up mp3 and directly switch to stop CD. The CD carries waveform files, which are completely in lossless sound quality format, which will give better results.
If you want to reduce distortion, the only way is to increase the bitrate. It’s best to use variable bit rate (VBR) compression to produce mp3 files, which can strike a balance between maximum fidelity and minimum file size.
Finally, if you want completely lossless sound quality, you should still use audio files in a lossless compression format or an uncompressed file format. How good is the sound quality in MP3 format? 128/192/256/320 etc What is the difference in MP3 sound quality of various compression ratios/compression modes? What are some basic principles? How about the sound quality of other formats like APE/WMA/etc?

Bit rate – definition

Bitrate

Introduction

BITRATE

The term quality is widely used.
In multimedia technology, quality is often used to judge the effect of audio, and quality here is actually bitrate.
On WINDOWS it is called “bit rate” and on some players it is described as ” bit rate “.
Quality refers to the bit rate at which digital sound is converted from analog to digital format. The higher the bitrate, the better the quality of the restored sound.
sound control edit stream
16 Kbps = phone quality
24 Kbps = increase phone quality, shortwave transmission, longwave transmission, European standard medium wave transmission
40 Kbps = American standard medium wave transmission
56Kbps=Voice
64 Kbps = boost voice (best bitrate setting for cell phone ringtones, best setting for cell phone mono MP3 players)
112 Kbps = FM stereo broadcast FM 128 Kbps = tape (best setting value for mobile phone stereo MP3 player, best setting value for low-end MP3 player)
160 Kbps = HIFI high fidelity (best setting for mid to high end MP3 players)
192Kbps=CD (best setting for high-end MP3 players)
256Kbps=Studio Music Studio (for music enthusiasts)
In fact, with the advancement of technology, the quality of music is also getting higher and higher, the highest quality of MP3 is 320Kbps, but some formats can achieve higher sound quality.
For example, the emerging APE audio format can provide real audiophile-level lossless sound quality and smaller volume than WAV format, and its quality is usually 550kbps-950kbps.
encoding modeedit stream
VBR dynamic bit rate (variable bit rate) means there is no fixed bit rate. The compression software immediately determines which bitrate to use based on the audio data being compressed. This is a method that takes quality as a premise and takes file size into account The recommended encoding mode;
ABR Average Bit Rate (Average Bit Rate) is an interpolation parameter of VBR. LAME created this encoding mode in response to the low file volume ratio of CBR and the variable size of files generated by VBR. Within the specified file size, ABR takes every 50 frames (about 1 second for 30 frames) as a segment. High-frequency and insensitive frequencies use relatively low traffic, and low-frequency and large dynamic performance use high traffic, which can be used as VBR and CBR, a compromise option.
CBR (constant bitrate), constant bitrate means the file has one bitrate from start to finish. Compared to VBR and ABR, the compressed file size is very large and the sound quality will not improve significantly compared to VBR and ABR.

CBR (Constant Bit Rate)

Bitrate is an unavoidable experience in video editing and music production.

VBR

The word bit rate sounds a bit complicated, but of course, video and audio files. It is also often found in various situations, such as mobile phones and internet lines.

What is the bit rate? It’s surprisingly useful to remember it sensually, so remember it.

I think the person who visited this page is a beginner asking “What is bitrate?” , So I would like to explain it in the easiest and simplest way possible.

Bit rate basics
To briefly explain the bit rate, it refers to the amount of data per second for communication, such as video files, music files, and the Internet.

The so-called reproduction and communication are data streams. This stream uses a unit called bps (bit per second) to indicate how many bits flow in one second (per second).

I think it is easy to understand if you can imagine the road that a car passes by. The car is the data and the data stream is the road.

Taking into account that a road with many cars carries many people and luggage, it can be said that a lot of data (information) flows. This is called high bit rate.

On the contrary, if there are few cars in motion, it can be said that little data (information) flows. This is called a low bit rate.

A state in which the amount of data is large and the bit rate of the stream is high

A state in which the amount of data is small and the bit rate is low

Should the bit rate be high?
A high bit rate means a large amount of information. If there is a lot of information, it sounds great, like high image quality for videos and high sound quality for music, but it has a big disadvantage.

The disadvantage of a high bit rate is that it increases the data capacity of a single file. If the data capacity is too large, it can take time to send data to someone or move data between hard drives, making it difficult to manage.

Therefore, the codec was developed to reduce data capacity while maintaining high image quality and high sound quality. I’ll talk about codecs another time, but you need to set the bitrate keeping in mind the balance between image quality, sound quality, and file capacity so that the data capacity is easy to handle.

How to check the bit rate
You can check the bit rate by looking at the detailed information of video files and music files on both Windows and Mac.

How to check bitrate in Windows 10
Click Properties in the context menu of the video or audio file for which you want to check the bit rate.

Variable Bit Rate

The bit rate fluctuates in a video or music data file. More efficient compression is achieved by increasing the bit rate (large amount of data) in the large change part (vigorous movement) and decreasing (decreasing the amount of data) in the small change part. You can expect the effect of reducing the amount of data while maintaining the quality or the effect of improving the quality while maintaining the amount of data, but it is generally used for the first purpose.

Variable bit rate
Bit rate at which the amount of data changes per unit of time. With the variable bit rate, the bit rate per unit of time can be adjusted according to the state of use of the line and the amount of data to be transmitted, so that the data can be transferred efficiently. Also, when compressing video to mpeg, etc., a compression method by changing the bit rate value according to the video.

What is the difference between CBR / VBR / ABR in audio / video conversion?

What is the difference between CBR / VBR / ABR in audio / video conversion?

CBR vs VBR vs ABR

Bit rate is an index that determines the quality of compressed video and audio. Bit rate is the number of bits per second, and generally the higher the bit rate the higher the quality. However, the file size will increase accordingly.

ABR vs CBR vs VBR

The compression method is the behavior of the bit rate at the time of compression, which is the constant bit rate method (CBR), the variable bit rate method (VBR) or the average bit rate method (Averate Bit Rate, ABR). be classified

Constant Bit Rate (CBR) functions

The compression method with a constant bit rate is called the constant bit rate (CBR) method. Since the bit rate is fixed, it is not only easy to predict the file size after compression, but it is also possible to search for the playback position at high speed. However, in the video there are scenes with little movement and scenes with a lot of movement. problems with such as quality change.

WAVE and uncompressed AIFF are also CBR.

advantage
It is possible to predict the size of the file after compression.
You can search the playback position at high speed.
Disadvantage
Quality tends to vary
Variable Bit Rate (VBR) Features
The compression method by changing the bit rate is called the variable bit rate (VBR) method. The VBR scheme places the jitter data with a high intense bit rate, the jitter is compressed by lowering the loose position, in its entirety the quality is kept constant can be compared with the CBR can be compressed with high quality if it is said. However, the size of the compressed file is unpredictable because the bit rate changes from moment to moment. Also, it takes longer to find the playback position than CBR.

advantage
Easy to control quality
High quality

Disadvantage
Difficult to predict compressed file size
It takes time to find the playback position.
Average Bit Rate (ABR) functions
Although the bit rate is variable, the compression method with a constant average bit rate is called the Average Bit Rate (ABR) method. Although the bit rate fluctuates with this method, the size of the final file can be predicted to some extent because it is compressed so that the average bit rate of all data is constant. This allows you to keep the quality as VBR and predict the file size as CBR. However, it takes longer than other methods because the data must be scanned at least once before compression.

advantage
It is possible to maintain quality to a certain extent.
File size can be predicted to some extent
Disadvantage
The compression process takes time

How to get the correct bitrate

How to get the correct bitrate
appropriate

bit rate

Here’s a simple way to get the correct value:

Bit Rate

Don’t increase the frame rate too much
Change the codec type
Check the resolution
If you’re taking up too much CPU on your computer with high-bit video, try the following.

Don’t increase the frame rate too much
Don’t lift too much

Since the frame rate is edited with basically the same settings as the frame rate when recording a movie, if you don’t increase the frame rate too much at the shooting stage, you can naturally keep the bit rate low and reduce the amount of data. may. Even if the resolution is a bit high, if the frame rate is low, like 24fps, there is no problem even if the value is low.

Change the codec type
Change type

By changing the type of program called a codec that compresses and converts audio and video data, it is possible to save high-quality videos even at low values. The codec type can be configured at encoding time, and the recommended codec is determined by the medium the video uses, so try switching to a better performing codec within the recommended encoding and range.

Check the resolution
check

Unless you have a specific purpose, the quickest way to lower the bitrate is not to edit with high image quality, such as 4K video. High-resolution videos have a large amount of information, so it is only natural that the bit rate is high.

So if lowering the resolution doesn’t reduce viewer comfort, try lowering the resolution a bit.

abstract
In this article, I explained the term bitrate, which is a must for anyone editing video. It seems a bit difficult compared to frame rate and resolution, and you should be able to set the proper bit rate by referring to this article.

By setting a suitable bitrate, you can create a video that is easy to handle with a small amount of data while maximizing the quality of the video.

How to make a video with the proper bit rate?
How to create?

I will explain how to create video with proper bitrate when editing video. Since various factors such as resolution, frame rate, computer specifications, and the media to be used determine the appropriate numerical value, it is problematic to think about every time you edit a video, and many people have so decidedly decided. appropriate.

If you refer to the bit rate guide presented above and the “How to set a suitable bit rate” explained below, it is not a difficult setting at all, so try them all.

Disadvantages of too high a bit rate
Demerit

Of course, if the value is set too high, the image quality will be high, but the amount of data will be huge, and the video may be difficult for the viewer to see. Problems such as stalling or getting stuck while playing a video will occur.

Not that there is a problem with the video, but the amount of data is too large, which puts too much pressure on the viewer side. Also, if you don’t have a high-spec PC, you won’t be satisfied with the edit in the first place, and there are downsides that it will take up a lot of storage.

What is the bit rate?

What is the bit rate?

bitrate

Bit rate represents the amount of data per second of video and is expressed as bps.

Bit Rate

Bps is an abbreviation for bits per second and 1 Mbps is 7.5 MB of data per minute. Since this value determines the amount of video data and the image quality of the video, those who edit the video should be aware of the appropriate setting method.

A video with a high bitrate value will have a lot of data and will be a heavy video that will take time to upload and download. High bit rate video has the characteristic of being able to express high quality and delicate images.

Those who edit videos need to acquire the minimum knowledge not only about the size of the video, such as the aspect ratio and resolution, but also about the bitrate that the amount of video data represents.

There are two types of bit rates
There are two kinds

There are two types of bit rates, which can be divided into audio and video. Generally, when editing a video, you should check the oval bitrate, which is the sum of these two types. The video is a complete work that combines audio and video, so there is no problem if you think about it in total.

Video cleanliness is determined by screen resolution x frame rate
Video cleanliness is determined by screen resolution x frame rate

The cleanliness of the edited video is determined by the resolution and the frame rate, and by setting the corresponding bit rate, the viewer can view the video in the highest quality. First, the resolution represents the number of pixels in the video and the upper limit of image quality is set at the recording stage.

Next, the frame rate shows how many images a video makes up per second, which is related to the smoothness of the video. By editing a high-image-quality video shot at the same frame rate as when it was shot, you can create smooth, high-quality video.

And the most important thing is the bitrate, and if this value is low, no matter how good the material is, it cannot be saved as a high-quality video. If you want to produce a beautiful video, you need to set it to a state where you can ensure the amount of data with a corresponding high bit.

What is the proper bit rate?
Suitable

The appropriate value depends on the quality of the video, but it is not always good to produce a video at a high bit rate so as not to reduce the quality. Since the value is the amount of data, the higher the value, the greater the amount of data, causing problems that cannot be processed by a low-spec personal computer.

There is a general recommended guideline based on resolution and frame rate, so it is recommended to configure it by referring to the following. Of course, if you are using a high-spec computer and want to produce a beautiful video with higher image quality, no problem, even if you produce a value slightly higher than recommended.

VBR vs CBR

Often times, you will want to adjust the bitrate when adjusting your video.

CBR & VBR

Many people find it difficult and annoying in technical terms, but if you don’t know it, you won’t be able to set it up correctly and the video quality will eventually deteriorate, so be careful. This article explains the meaning and function of bitrate in an easy-to-understand way, but if you want to understand it in detail, take a look.

Also, it is especially important that the standard bit rate is determined by the resolution and the frame rate, but it is better to change it at the same time as much as possible. This time, I will also introduce the operation procedure with the highly rated “iMyFone Filme” tool that you can set all three at once, but let’s download with the button below and try it together.

Part 1: What is the bit rate?
Bit rate indicates the amount of data that can be sent and received per second, and the unit is bps (bits per second). For example, if the video bit rate is 1 kbps, it means that 1000 bits of data can be transferred per second.

And if you break this down more concretely, there are the following three types.

“Video Bitrate

By analogy with the basic definition, video bit rate refers to the amount of video data per second. This value is calculated based on RGB data, frame rate, and resolution displayed by the color information contained in a pixel.

Bit rate of “speech”

Similarly, the audio bit rate refers to the amount of audio data per second, but the value is calculated using the sample rate (Hz) and the bit depth (bits). The first indicates how many times the sound is divided and recorded, while the second shows the amount of data per recording.

Bit rate “oval”

Speaking of the calculation formula, it is “oval bit rate = video bit rate + audio bit rate”. Also called total bitrate, this is also what commonly used video bitrates mean.

The Truth About High Bitrate Lossy Compression Part 3

The Truth About High Bitrate Lossy Compression Part 3

BITRATE

For most users of the MP3 format, the problem of high quality sound is usually phrased as follows: “256 or 320? Or maybe try VBR?”

Bitrate

And this question haunts them day after day. Not all recordings sound good at 256; there is a strong audible and visible (measured) loss in the high frequency range. When using VBR mode (the so-called variable bit rate stream), it often happens that music sounds better by ear than 256, but this should not be taken as a general rule of thumb. Encode low-value or poor-quality records – you can’t go wrong. I have selected the VBR parameters to get the highest quality for VBR.

For the commercial LQT format, there is only one encoder proprietary to the authors: Liquifier Pro. We push them. Note that the LQT format is originally based on VBR encoding, so there are simply multiple modes for it, such as “bad”, “good”, and “excellent”. Naturally, for our tests we took the “excellent” (audiophile) mode, which results in a stream of 192 to 256, most of the time 200-220 kbps. Let me remind you that the LQT format is based on the MPEG-2 AAC family of algorithms. Also, this is the highest quality AAC implementation to date (tested on analogs).

The OGG format is a relative of the MP3 format, but it contains a different psychoacoustic model and some technical innovations that MP3 does not have. For starters, OGG initially only supports VBR mode. The user sets the approximate bit rate and the encoder tries to compress as closely as possible. The range of variation is extremely wide: 8 to 512 kbps, and it is much more discreet than MP3. The top bar is up to 512 kbit / s, whereas nowadays MP3 encoders really only “pull” up to 320. You may ask “is it possible that even 320 is not enough?” Yes, it happens, but rarely.

Roxette samples
Well, we come to the most interesting part. Let’s start with my auditory sensations.

For MP3 in a 256 kbps stream, noise disturbances at high frequencies are clearly audible. Not only is a considerable part of them absent from the sound, but strong distortion, wheezing, clanging and other “charms” are also mixed in. This is a sign that 256 is clearly not enough, therefore you need to test higher. Let’s take a 320 compressed sample. The sound has changed significantly, this is a completely different matter: the upper part is in place, no differences by ear were found. For the purity of the experiment, let’s see what happens in floating flow mode. We obtain an average bit rate of 290 kbit / s, of which the conclusion suggests that 256 for the sample under study will not be enough. In fact, a sample encoded in VBR mode sounds a little better than 256, but it clearly falls short of 320. In the case of MP3, for high-quality compression, only encoding in 320 kbps mode is adequate, ie , to the maximum of opportunities.

Let’s take OGG as “modified MP3”. There are five approximate bit rates for the encoder: 128, 160, 192, 256 and 350. Well, let’s try 192 and 256. We will not take 350 bit rates, because we already know that MP3 at 320 kbps clearly transmits excellent quality, it seems that better not necessary. For 192 mode, we get an average stream of 226, and for 256 mode, up to 315 kbps. So far the precision. Such a large deviation from the reference point is a signal for sound material that is very difficult to encode; with a sample with a simpler density, the precision will be higher. To be honest, I tried to evaluate 320 MP3 and 315 OGG for a long time and came to the conclusion that they both sound almost identical to the original sound. But they are based on different psychoacoustic models and their sound coloration is different. Personally, I liked the MP3 a bit more. But, this is really a controversial issue; after all, the OGG encoder is just a beta version. When there is a release, I think it should surpass MP3 in quality. Comparing them separately to the original, I was inclined to believe that the OGG has an even closer sound to the original, but there is something wrong with the high frequencies of this encoder. Because of this, MP3 sounds a bit better. I don’t think it is necessary to say that in 350 mode (average bitrate was 365) OGG “perfectly” repeats the original.

Now we are talking about the little-known but widely advertised format as the “highest quality”: the LQT format. And most importantly, it sounds great overall, however after listening to it, I realized that I didn’t like its sound. It doesn’t distort high frequencies, like MP3 256 kbps, but it smears the sound and smears a lot. Loud sounds fade over time.
