Lets try to read about the differences:

 

what is the difference between mp3 and mp4In our ever-modernizing age, things are constantly changing and being updated. What the standard was yesterday may not necessarily still be the standard today. All of these quick changes creates a market with tons and tons of options when it comes to every aspect of our lives.

Music is no exception. For years, MP3?s were the standard for music files. Then that all changed as more extensions were developed and released. Suddenly MP3?s werent the only things available. One of the extensions that came around was MP4.

MP3 and MP4 sure sound similar, one might just assume MP4 is the next step for MP3, but that is not the case. In fact, they are rather different, with distinct histories and uses.

Lets examine the difference between mp3 and mp4 by looking at what each file extension is individually.

 

MP3

what is the difference between mp3 and mp4MP3 is short for MPEG-1 Audio Layer 3. It is used for audio and uses a compression algorithm that introduces loss, meaning it is a lossy compression format. It is one of the most commonly used audio formats available and has been the standard for quite some time.

Uncompressed audio files are rather large, just look at any WAV file. This is because sound is very complex and the translation of it into a digital format that a computer can understand takes a lot of data.

 

MP3 works to make file sizes smaller by using what is called psychoacoustic models. They get rid of data that most people would not hear because it is too low or high. By doing this, files sizes can be greatly reduced. A 128 kbit/s MP3 file is about 1/11ththe size of the corresponding file on an uncompressed CD.

MP4

what is the difference between mp3 and mp4MP4 is short for MPEG-4 Part 14. MP4 is based on MPEG-4 Part 12 which was in turn based on Apples MOV file type. MP4 is a container format, meaning it is used to store audio and/or video data, rather than to code the information. MP4 video and audio can also be streamed over the internet. This is also true of most other modern container formats.

Because MP4 is a container format, it does not have a standard method of coding the audio or video information. Instead, codecs dictate how the audio or video will be coded and possibly compressed. For audio, Advanced Audio Coding, or AAC, is the most popular codec for compressing audio for transfer on the internet.

So Whats the Difference Then?

From these two descriptions, we can note a few major differences. First, MP3 is an audio compression format used to compress and store audio on a computer. MP4 is a media container format used to store media of many possible types on a computer.

Therefore, an MP3 file is limited with regard to the method of compression and can only store audio. MP4 on the other hand, can store video as well as audio. It can even store subtitles for a video file. Also, since MP4 is a container, it can store audio and video that have been compressed in different fashions. In fact, an MP4 file could be audio that has been compressed as an MP3.

These differences make it so that a program that plays an MP3 cannot necessarily play an MP4 and vice versa. The same goes for portable music players, though there are plenty of software options and portable players out there that can play both, for example Winamp.

Both formats have their uses and things that they are better at than the other. Do you have any opinions on what each format does better? Let us know in the comments below.

The main idea is to let you extract mp3 files from mp4 files, extract mp3 audio from mp4 videos.

Mp4 to Mp3 converter, how to extract mp3 from Mp4?

Its possible to extract mp3 files from mp4 video files?

Yes, it is possible to convert mp4 to mp3.

You can take any mp4 video file and extract the audio into an mp3 file.

In fact you can do the same from a flv file or from most video files. (flv to mp3 converter, avi to mp3 converter, mpeg to mp3 converter, etc)

So the situation will be video to mp3 converter.

But very soon you will be able, not only to have an mp4 to mp3 converter, but to normalize, equalize, etc. the mp4 video file itself. Correct or normalize the mp4 or even to normalize a flv file, nolize avi, normalize mpeg, normalize video file.

Just keep in touch and very soon we will release the Mp3Doctor PRO plugin to achieve all that!

Volume Boost – Volume Booster

Volume Boost.

Without any question, one of the hottest needs of the mp3 users are to find a way to Boost the Volume level of any mp3 file.

The situation is very common and well known: When you listen to your mp3 files, you find that the volume levels are quite uneven. Then you discover that you need to boost the volume level.

…After some time, and some pain (trying different solutions), you learn that its not only a matter of boost the volume level, but that you need to normalize it, optimize it.

Then, finally you get into Mp3Doctor PRO and find that its exactly what you was looking for, because it standardize the volume level of all your mp3 collection, and at the same time, let you equalize it and maybe even change the pitch or change the tempo.

Volume Boost – Volume Booster

No matter if you plan to listen your music on your PC or using headphones, or maybe in a portable device, on your car audio system or by any other way, it will sound great,

Mp3Normalize – a perfect example of a good mp3 normalize

Just watch the video and listen to it.

Yes, it was normalized usign Mp3Doctor PRO (yes, it was normalized > mp4 normalizing).

The original sound was low (as many mp3 and mp4 files) at least in some parts of the music. So we normalize it and made this cideo to show it to you.

The benefit is so obvios, no need to comment anything else.

Mp3 Normalize example of non linear normalization

Good mp3 normalize example, with non-linear normalization.

Thats right. This mp4 video is a good example on how Mp3Doctor PRO does a non-linear normalization. In this case, we use non-linear as the mathematical approach, meaning “a system whose output is not proportional to its input”.

But lets go less technical and pay attention to the mp4 video (yes, we normalize the mp4 file using the alpha version of Mp3Doctor PRO, whic will be available very soon!).

The important thing to notice is that lower parts raises more the volume level than higher parts of the original. Another thing to notice is that the bass and the guitar get pushed too (bass boost and guitar boost).

Pay attention to the mp4 video:

This next mp4 video, show some mp3 normalize very similar:

The volume increase is more powerfull on low volume parts of the song, and software in higher parts. However, even in the higher parts, some instruments get a volume increase bigger than the vocals, per example.

Mp3 Normalize, a perfect example of a good mp3 normalizing

Mp3 Normalize, listen this example.

Often in this blog we discuss aboutMp3 Normalize methods and their theory.
But its time to watch and listen some good examples of mp3 normalizing in action.

This first video will be a perfect example on how the Mp3Doctor PROmp3 normalize works. Because it does not only raise or amplify the volume level. It also boost the bass and “define” better other instruments.

We choose some jazz file because its a nice and clean example of the possibilities of a good mp3 normalization (volume normalization, equalizing, etc)

If you listen carefully (and maybe even if not) you will notice, in first place that the volume level was normalized and optimized, not only amplified. It was normalized at different values each milisecond, to make it as best as possible.

Also you may notice the bass boost, the great bass boost i could say. The other instruments also improve their sound and presence. Listen it again and pay attention.

You may also had noticed that we was normalizing a mp4 video file too (maybe next Mp3Doctor PRO version will have that feature, and if you purchase your copy today, you will have full rights to upgrade when its released!).

In a next post we will share more great examples of mp3 normalize feature.

Mp4 audio normalizing

Mp3Doctor will add Mp4 audio normalizing in a future?

Well, this is not an official announcement, we are just giving you a shot of what we are doing in the codebox of Mp3Doctor PRO.
But yes, we are testing an alpha version that allows to normalize and tweak the audio of any mp4 video file (in fact, of almost any video format file).

Normalize, equalize, modify tempo and pitch of any mp4 video file

This mp4 video (used to demonstrate the usage of Mp3Doctor PRO) allow you to see how we can normalize the volume level of any mp4 video file.

This other mp4 video (used to demonstrate some Mp3Doctor PRO features) can show you some of the things we can do in mp4 videos using Mp3Doctor PRO new version (not available yet).

Mp4 audio normalizing, mp4 audio tempo change, mp4 audio pitch change, mp4 audio equalizing (yes, this is fantastic to improve the sound quality of any mp4 video file!).

Just keep in touch!
