What is the difference between MP3 and MP4? Part 2

At present, MP3 has entered a period of rapid growth and is slowly moving into a period of maturity, and the market has been formed on a large scale.

MP4 is in the market introduction period. Since ARCHOS released the first MP4 portable theater in 2002, many companies are optimistic about the development trend of MP4. The development momentum has become the latest growth point of mobile digital technology, and its development potential is even greater. than that of MP3 In about 3-5 years, it will form a huge market of nearly 10 billion in China. MP3 and MP4 will coexist and develop together for a long time. Ever since Sony invented the Walkman in 1978, portable music has reached people. Until 2004, the Walkman went through the Walkman-type tape, CD, and MD process. Today, it has become a digital MP3 Walkman, and Walkman music has become more portable and fashionable. In fact, as far as MP3 is concerned, with the further improvement of sound quality, the sound quality has approached CD quality, and the “listen” function of the Walkman has reached its peak. Many manufacturers began to consider the needs of consumers from other aspects, so a large number of multifunctional MP3 players began to appear on the market, and the Gmini400 of the French company ARCHOS even appeared in the MP3 player that can watch movies and play games. games. . So, in terms of technology development and trends, the integration of multifunction will be the final direction of MP3. However, although the growth of the MP3 market is amazing, MP3 can only be limited to the world of “listening”. To meet people’s need to “watch” with other people, ARCHOS, a famous French mobile digital manufacturer, proposed the concept of MP4 portable theater in 2002. And launched the world’s first MP 4 player, MP4 sounds very similar to MP3 in name, however, the functions between the two are very different. The main advantage of MP4 lies in the video aspect, and the perfect video function can make the dream of people who watch movies wherever they go come true. We know that the biggest shortcoming of MP3 players is that they can only hear your voices and not see your people. Although there are many large-capacity color-screen MP3 players on the market, they generally fall short of seeing pictures. and cannot enjoy video files. , what must be said is a pity. And MP4 is different. You can listen and watch, and it has rich entertainment functions. It is an entertainment novice in the digital age, and it is a big step forward than MP3. At present, most of the international manufacturers consider MP4 as their flagship product and add many popular features to MP4. Among them are complete portable theaters like the ARCHOS AV400. AV400 is based on video playback, audio playback, video recording, voice recorder, nearly 10 functions such as video output, mobile hard drive, digital camera add-on function have won the title of “Almighty King of Digital Entertainment” from just one time. At the same time, other MP4 functions on the market are also very rich. Entertainment pioneer. Take ARHCOS AV420 as an example, equipped with a 20GB hard drive, it can store more than 30 movies in MPEG-4 format, record and play 5000 pieces of music, and store tens of thousands of digital photos for up to 40 hours of TV. shows 3.5-inch TFT color LCD screen can play digital movies, recorded TV and digital photos in DVD quality, as well as excellent video playback and video output; support MP3 digital music playback, 30-320 kbit/s stereo MP3 music decoding, almost CD quality, support CBR, WMA, AAC format music; support CF card slot, can be used as a digital companion, using USB2. 0 fast transmission interface, can be used as a mobile hard disk. The industry believes that this kind of pocket-size digital entertainment product, which is compatible with MP3 and is based on “MEGP-4 dynamic picture decoding technology, can perform” move with you “(movies) on the TFT screen at high-definition color, you are taking with powerful audiovisual functions.”The magic wand of MP3 guides the development of digital mobile technology. However, although MP3 and MP4 have similar names, they are not completely substitutes. The appearance of MP4 is not to kill off MP3. The relationship between MP3 and MP4 is like the relationship between CD and DVD.

What is the difference between MP3 and MP4?

MP3 technology has been around for a few years.

On an ordinary music CD, it can only contain 60 to 90 minutes of music (about 15 songs), but if MP3 technology is used, the number of songs that can be stored on a CD of the same capacity will be ten times elderly. from a normal CD! —- MP3 uses MPEG Audio Layer 3 technology to compress ordinary sound information with a compression ratio of 1:10 or even 1:12, but it does not sound distorted to the human ear. —- There are many programs that can play MP3 files on the Internet, such as winamp, which is good. If your sound card also supports SRS technology (introduced in the previous issue of this edition), you will definitely enjoy more beautiful MP3 sound. glad. If you mean media format: MP3 music compression format encoding algorithm is taken from MPEG-1AudioLayer3, that is, it is part of MPEG-1 audio encoding algorithm. MP3 not only has a high compression rate, but also has a high fidelity of compressed music, so it is very popular with Internet users. On the other hand, MP3 also brings copyright protection issues. For this reason, many companies are researching new music compression formats that can effectively protect copyrights. MP4 is a format designed by GlobalMusicOutlet. Although MPEG4 is also often used by simply called MP4, but there is no relationship between the two. Compared to MP3, MP4 has a higher compression rate and fidelity. MP4 files are executable files with built-in players and carry the original copyright owner’s web address and copyright notice. In addition, MP4 also uses a special digital watermark technology, which can detect the music source even when MP4 music is played via FM/AM radio. MP4 has made many new attempts at copyright protection, and is expected to be welcomed by publishers, but certainly not as popular as MP3 by most Internet users. If you mean the player: We know that the biggest drawback of MP3 players is that they can only hear your voices and not see your people. Although there are many large-capacity color screen MP3 players on the market, they generally remain at the image display level It’s a pity that you can’t enjoy video files. And MP4 is different. You can listen and watch, and it has rich entertainment functions. It is an entertainment novice in the digital age, and it is a big step forward than MP3. At present, most of the international manufacturers consider MP4 as their flagship product and add many popular features to MP4. Among them are complete portable theaters like the ARCHOS AV400.

The relationship between MP3 and MP4 is like the relationship between CD and DVD. Although they are aimed at partially overlapping consumers, they are not the same. MP3 is mainly for music lovers. In terms of MP3 music playback, MP3 works well and MP3 offers lower price and has spread very quickly in recent years. And MP4 pays more attention to video features and future digital entertainment features, focusing on the digital entertainment era, and its positioning is quite different.

Can you improve the audio of an mp4 or normalize its volume?

Boost the loudness of an mp4

We all know that for years it has been possible to normalize an mp3. The algorithm has been improving and modernizing, but it was already possible to achieve it decades ago.

However with video files, for example mp4, there is always the question whether it is possible to achieve the same result as with an mp3.

There are people who are even fond of downloading mp4 files and want to convert them to an mp3,

Mp4Gain is capable of performing all these actions, with great quality and power.

Finally, a video co-container is just that, a container that has several files inside it, including audio ones.

Beyond technicalities, it is possible to improve the audio quality and volume of an mp4 or any other popular video format using Mp4Gain.

As we mentioned, it is possible to convert between different video formats or extract the audio from a video format and leave it as an audio format, that is something very current.

Well nowadays it is very easy to get the video of a song and Mp4Gain can extract the audio from any video.

What does normalize audio mean?

Audio normalize

The volume of sound is measured in decibels and a video or a song, that is, the audio can have more or less volume.

On the one hand we have that the audio or video file already has a “quantity” or a volume gain. That is, there is an initial volume level.

On the other hand, we would have the volume that we would assign to the amplification of our audio player.

In this case, for audio normalization we will refer to the input volume level or gain.

What happens if an audio file has noticeably lower gain? Well, it will sound at a lower loudness unless we manually modify the volume knob, which is annoying and inconvenient.

That is why the idea is that the volume input gain is optimal. Without distortion, but at a good volume.

Mp4Gain is the best software to perform this function, it is not limited to mp3s and even performs it on video files. Additionally, it can be used as a converter since regardless of the format of the input file, we can choose the format we want the output file to have.

For example if our input file is an mp4 video, we can choose to get an mp3. Thus we will have extracted the music, we normalize it and we obtain only the audio in an mp3.

Mp4Gain has many very useful functions to improve the audio quality of your songs or videos.

The audio compressor or normalizer

Adjust volume level

Many instruments tend to be very dynamic, and when recorded can result in large note amplitudes, some very strong and some very weak. We could imagine following the volume of each of these tracks through the fader race of our console, but even with a very good automation system, this task could be very long and very complicated.
This is where the compressor or normalizer comes in. It is used to restrict the dynamics of an audio signal, making it easier to find a more stable level in the mix and to have an optimal volume level.

Here is the diagram of a sound wave recorded without compression and with compression:

How to adjust a compressor?

As you can see, when applying compression, the dynamic range of this wave has been reduced. In the original wave, the difference between the lowest amplitude and the highest amplitude is around 15 dB. After applying compression, the dynamics are only 5 dB. What happens is that the compressor detects and compresses the loudest sounds in the wave. After compressing these louder sounds, I can raise the entire level of the wave, so that the weak and strong notes are leveled out in the rest of the mix.

Threshold :

Compressors, like all dynamic processors, including the normalizer, work by measuring the amplitude of an incoming signal relative to a reaction point that must be configured to tell the compressor when to start operating. This reaction point is called the threshold.

Consider our example of watching TV and turning the volume down when advertising. We all have our own threshold that tells us when a sound is too loud and that will force us to take the remote control to lower the volume. This volume level is our threshold. The threshold that is, in fact, the most important component of any dynamic processor.

How to adjust a compressor?

In a compressor, a signal level above the threshold will activate the compressor, while a lower signal level remains unchanged

Normalize the volume of an mp3

For several decades, with the appearance of MP3, it has become a customary practice that people accumulate a large number of music files, mainly in MP3 format.
Some people get to accumulate thousands of songs in the MP3 format. which are easily transported with a pendrive using any other device, to be able to listen to them anywhere, and at any time.

This is very comfortable because one does not need to load any hard disk and much less large numbers of CDs or cassettes.
but it has the disadvantage here when mixing the songs that comes from very different recordings, times, etc. It occurs very frequently in volume level differences.
It is a typical problem today, want to Play favorite songs meets the fact that some sound much louder than others. And this eventually becomes a problem.

for this the volume normalizers have been created. The volume means all the songs have a volume as optimized as possible every possible level that each of them can play.
Volume normalizers have also existed for decades, and their algorithms to achieve amazing results. today download Mp4 Gain and check results no other software can offer. Russian other options How to change the pitch of a song Without altering its speed on the contrary modify the speed without affecting the Pitch. You can also equalize it and perform various functions that will be very useful.
