1. Chapter One - Why to convert YouTube to MP3? 

Music warms our life. Every song tells a story.

1.1. A popular song

Type “Look What You Made Me Do” in Google, and you will see the first search result page is a music video from YouTube with an extraordinary views, exceeding 1 billion.

This song is recorded by a brilliant singer-songwriter Taylor Swift, released in 2017 as the lead single from her 6th album Reputation.  

“Look What You Made Me Do” is about struggle against the past rough and glossy times Taylor had gone through and her critical attitude towards those times. In the end, Taylor is standing up and defending herself even if it means that she has to stand alone against the world just as the lyric says “I’m sorry the old Taylor can’t come to the phone right now - Why - Oh ‘cause she’s dead”. It’s about recreating yourself and becoming who you really want to be even after the darkest moments. It’s the song to listen to when you are in dark days.

It’s not hard to find out that you can only watch MV on YouTube and there’s no MP3 track to play. Even on Spotify and other music and podcast streaming platforms, MP3 audio track for “Look What You Made Me Do” can’t play. Of course, it can play if you subscribe a membership. A question arises whether it is possible to extract MP3 from YouTube MV and how. The answer is yes and the details will be shown in Chapter Two.

1.2. More popular songs

“Baby I’m dancing in the dark with you between my arms” spiraling in the air, the lovely song dances out of an official MV for a single “Perfect” posted by Ed Sheeran on YouTube in 2017.

“Those were the worst years of my life as I went through both physical and emotional battles. I was able to turn that fight into music I’m really proud of. I wrote songs in my bed and on the couch and recorded there mostly as well. Words and lyrics that were so true to my experience came pouring out of me effortlessly.”

Avril Lavigne said on releasing "Head Above Water" as lead single in September 2018, in which Avril shouts out “I’m too young to fall asleep”. In 2015, Avril told to a magazine that she had been diagnosed with Lyme disease.

On May 17, 2018, YouTube announced a new version of the YouTube Music service, including a desktop product and redesigned mobile app, providing all sorts of official albums, playlists, singles, music videos and more. It’s a must to subscribe Music Premium membership if you prefer an ad-free and background streaming and downloading for offline playback. It’s a monthly subscription.

You may ask whether there is a way to download music from YouTube to desktop or portable devices or how to download YouTube Music to MP3 to enjoy anytime and anywhere without subscription. The answer is yes and the detailed information will be described in Chapter Two.

1.3. Original instrumental music

Musical instrument often creates magic moments when you are fully diving in your own feeling alongside each musical notation.

Uncountable creators around the world update their original music videos on YouTube to show their feeling and attitude to the world they sometimes like or sometimes hate. Viewers are looking for emotional connection with them to find a place and period that is able to calm them down or pour out their deep feelings. Then it’s possible to think of using self musical instrument to play the impressing one.

“No instrument is easier than another, any instrument takes a lifetime to master”. That is what we are often told.

You are able to play 10 popular songs in the first month if you can bear your finger hurt. If that is true to you, guitar is your cake. The piano, similar to guitar, is mechanically easier to play than the violin. To play a piano, you can get the right note when you hit the right key. With the violin, it requires a blend of muscle memory to get the right spot on the fingerboard and ear to make a quick correction if you are off a wee bit. Of course, your preference holds the final decision.

Type “violin” and search. Find the music video you prefer, and play one time, two times, three ... Open YouTube App on mobile phone, the searched video keeps playing given the mobile screen keeps bright and click the PLAY button each time. You may ask whether there is a means to convert YouTube video to MP3 to play freely on potable devices. The answer is yes and details lie in Chapter Two.

1.4. Why to choose MP3 format? 

MP3 support remains almost universal, including all popular media players, portable media players, smartphones and tablets.

What’s MP3? MP3 is a coding format for digital audio. MP3 uses lossy data-compression to encode data, a technology method applying inexact approximations and partial discarding of data. This allows a large reduction in file sizes when compared with original audios. Small size and acceptable fidelity have given rise to several booms in the distribution of music over the internet.

How MP3 compression works? It works by reducing the accuracy of certain components of sound that are considered to be hard to distinguish by most humans. The remaining audio information is then recorded according to different file sizes.

What’s the relationship between the amount of data and the sound quality? When creating an MP3 data stream, there is a balance to be decided between the amount of data to be generated and the sound quality of the results. The person producing an MP3 selects a bit rate, which sets how many Kbits per second of audio is desired. The higher the bit rate is, the larger the MP3 data stream will be, and, generally, the closer it will sound to the original recording. With a too low bit rate, the resulting sounds won’t be quite true to the original recording.

How does encoder affect the quality of MP3 audio? Besides the bit rate of an encoded piece of audio, the quality of MP3 audio also depends on the quality of encoder algorithm as well as the complexity of the signal being encoded. As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders do feature quite different quality, even with identical bit rates. Quality is dependent on the choice of encoder and encoding parameters.

What else can affect the quality of MP3 audio? Perceived quality can be affected by listening environment, listener’s attention, and in most cases by listener’s audio equipment (such as speakers and headphones).

Therefore, MP3 format is one of best choices for audio track to be extracted from YouTube videos or downloaded from YouTube playlist and albums.

Let’s dive into the following part, Chapter Two: How to convert YouTube files to MP3?

2. Chapter Two - How to convert YouTube to MP3?

This Chapter intends to give you a detail description of the tools to convert YouTube to MP3. Those tools are divided into three categories: online converter, desktop software and mobile app. The following will go on from the similarity and difference among these three categories.

2.1. YouTube to MP3 Converter online

2.1.1. Similarity

The similarity is described as follows. Payment: free of charge

A music buff who is crazy about YouTube original songs may need an online tool to download them to his/her portable devices to play back anytime and anywhere. If free of charge to use, it would be even better. Those online YouTube video to MP3 converters are generally free of charge.

A buff is someone who has a strong, special interest in something. Someone who loves R&B music is a R&B buff. Someone who is deeply interested in cartoon is a cartoon buff. Input source: link or URL

YouTube MP3 converter online often analyzes links or URLs of videos and audios from different source websites to extract data you desire to output in different formats, for example, YouTube link to MP3. URL, also known as a Uniform Resource Locator or web address, is the address of a resource on the Internet. A URL indicates the location of a resource as well as the protocol used to access it. Output formats: MP3, MP4, MKV, and more

Each online converter tool is capable to support no less than two popular audiovisual formats, MP3 & MP4, for example. As discussed above, MP3 support remains near-universal, including almost all media players, portable media players, smartphones and tablets. If you intend to keep music with smaller file size, use YouTube Video Converter to MP3 music. If you have sufficient space on your devices, you can try MP4 because you can not only enjoy music, but also watch videos. The remaining needs can be met, with other supported formats MKV, WMV, AVI, FLV, etc. Acceptable speed: the same impact factors

Each of them provides an acceptable converting speed. It’s impossible to always retain the same converting speed, as fast as several seconds, for example. It varies according to the length of files you are to download. To be specific, when changing YouTube to MP3, it takes a minute, more or less, to detect a four-minute music video link. The additional delay might or might not be needed, depending on your network speed and whether your internet connection is stable. Besides, different formats or resolutions you choose to download will also affect the time you spend. The time to download a 2160P video is definitely longer than a 720P video. Simple steps: three or four

How to download YouTube videos to MP3?

Step 1: Paste a link/URL into a text box

Step 2: Choose a video or audio format to convert

Step 3: Hit the DOWNLOAD or CONVERT button

Step 4: Choose a dictionary to save

An exchange may come up between Step 2 and Step 3 for some free YouTube to MP3 Converters. Such friendly operation steps make it easy to turn to another one when the format or resolution you desire isn’t supported. Output quality: no apparent difference

There exists no apparent difference in quality to output unless you are an audiophile or videophile who may find slight distinction among them. If you judge the quality by definition, some online YouTube MP3 converters stand out from a crowd that support to choose different resolutions for each format. Any dictionary to save

It doesn’t matter which website you choose to use. You can save the output to any dictionary you want.

It doesn’t matter which format you pick. You can save the output to any dictionary you want.

It doesn’t matter which resolution you select. You can save the output to any dictionary you want.

It doesn’t matter which device is handy. You can save the output to any dictionary you want.

2.1.2. Difference

The difference of online converters is described as follows. Source websites to support

Focus on just one thing at a time, which is a shortest way to arrive at a destination and then keep going. YouTuFab is presently targeted to extract audios and videos from YouTube files. It means now this website focuses on providing tailored solutions for YouTube fans.

Plant seeds in several places in the meantime, a colorful world waiting in a day which is not too long to come. Many websites intend to provide a key to users who need to open a door behind which crowd all sorts of audios and videos. You may count, a digital music service - Spotify, a social media giant - Facebook, a movies & TV shows provider - Netflix and other popular platforms. Formats to support actually

I have tested many websites in a row of Google search result pages and find a common problem. Although plenty of formats are listed clearly in a drop-down menu, this isn’t the essential and necessary condition enabling you to finish the last step of conversion to those formats. Maybe You will be shown in the last step a cool sentence: An error has occurred. Please try again. Eh... The best way to judge which formats online converters support is to try, and try again. Resolutions to choose

Not all online converters provide different resolutions for users to choose. YouTuFab is an exception. Although, at present, it doesn’t provide so many formats to convert, varied resolutions are still provided for each supported format to meet users’ needs to enjoy different watching and listening experience. Please be informed that the higher the resolution you choose, the larger the file size is to output. Plugin or software involved

It’s disturbing to find, at the key step or the final step, you are shown a picture or sentence expressing you need to load some tool in order to finish your conversion process. YouTuFab is independently developed and updated to convert YouTube to MP3 without any java, any 3rd party plugin, or extension. It’s definitely true that no software needs to be installed during the whole process of converting YouTube to MP3 online.

2.1.3. Top Three online converter website in 2019

2.2. Desktop YouTube to MP3 converter program

Compared with online converter website, the desktop converter program is more stable and updated continually, which makes sense to some extent. In order to give you a clear picture how to classify those programs, we invite a monkey called Tom to tell a story.

2.2.1. A story: Tom has a sailing dream

In a colorful village lives a monkey. Villages call him Tom. When he was a child, he had a dream of sailing across an ocean. Tom said it’s a small dream, with a smile from ear to ear. He told himself the first step was to earn enough money to buy a sturdy sail from a famous brand whose boss used to be a veteran sailor. Two branch roads

Now, we arrange two roads for Tom.

Years later, Tom was 20 years old. One of his kind relatives gave him a sail as a birthday gift. He was so pleased to accept the gift and devoted himself in practicing day and night. This gift equals to a category of free desktop YouTube to MP3 converters, single requirement-oriented and without payment.

Turn to the second road. Years later, Tom was 20 years old. He was surprised to find the amount was sufficient to buy a sail from that veteran sailor. He bought it and then devoted himself in practicing day and night. The sail of this time represents a category of paid desktop YouTube to MP3 converters, single requirement-oriented and with a payment. Prepare itself well

Before starting off, Tom should equip the beautiful sail with an alternative engine, life raft, water, food and other necessities to meet his different needs. Video converters intend to provide solutions to convert videos to a variety of formats. The source is a real video not a URL. In general, the loading speed and converting speed of desktop program is faster than online converter tool. If you want to convert YouTube to MP3, you need to download YouTube videos and then drag the source to the video converter before starting conversion. This kind of products is multiple requirements-oriented and needs to be paid. Sail across an ocean

On a sunny day, Tom wore a handsome sailing suite and set out to realize his small dream. On the sailing road, he was preparing to fight against storms, hurricanes, pirates and fear of the dark night. Tom became much stronger and tougher. The same case occurs to YouTube to MP3 converters and video converters, amongst which a difference in performance will be come out after continuous tech upgrading and individual solution to various requirements. For instance, DVDFab YouTube to MP3 is a well-designed tool to assist you to download a YouTube playlist with a VIP download speed.

A month later, Tom returned to the colorful village, villagers crowding on the wharf and greeting him warmly.

2.3. Is it legal to use YouTube to MP3 Converter?

YouTube to MP3 converters are merely technology, and technology is neutral itself in law; It’s what people do with that technology that makes it legal or illegal.

It’s not illegal to download a movie or a song; it’s illegal to upload it to become a publicly-available file without permission of copyright owners. You may find that people get sued for spreading unauthorized works to others or reselling them to make a profit, but are never sued for downloading. They are sued for sharing.

Therefore, the illegal cases may hide in how you do with the files that you have downloaded from YouTube with YouTube to MP3 converters.

After you finish downloading a MP3 audio track, you keep it personally, then it should be safe for you, but not if you share it with someone else, even for free. You don’t own the original contents, therefore, you have no right to redistribute to anyone, unless you are permitted.

3. Chapter Three - Where to find and how to download those online and desktop YouTube to MP3 products?

Online YouTube to MP3 converters are more suitable for occasional use to convert YouTube videos to MP3s for offline enjoyment.

Desktop YouTube to MP3 programs offers better speeds and the ability to convert even a playlist at a time, so if you regularly convert YouTube videos to MP3 or convert a large number of YouTube videos at once, desktop YouTube to MP3 converters are the best option.

4. Chapter Four - Others

Technology goes beyond your imagination.

4.1. YouTube Copyright

Virtually everything of interest on YouTube is copyrighted content, although creators edit content in many unimaginable ways to deceive YouTube into thinking it is original.

For a long time, YouTube turns a blind eye to contents uploaded for public viewing without permission from copyright owners while announces an official hard-position on copyright. That’s easier said than done. The reality may be 90% of the content on this video-sharing platform is clearly copyrighted and clearly used without permission. It seams they make no practical effort to evaluate whether the uploaded content is original, duplicate or fair use. The duplicate content stays up until the copyright owner complains. Then, it is removed. By YouTube's own rules, YouTube cannot exist. And yet it does.

Over years, YouTube has been suffering from lawsuits and disputes regarding its too small number of actions and measures taken to prevent the uploading of copyrighted material.

It seams YouTube repairs its image to some extent after Content ID system takes effect.

Content ID is a digital fingerprinting system used to identify and manage copyrighted content on YouTube. This system creates an ID File for copyrighted audio and video material and stores it in a database. When you upload a video to YouTube, it will be compared against the database, looking for any matches. When this occurs, the content owner can choose to block the video to make it unviewable, tracking the viewing statistics of the video, or adding ads to the infringing video and the ads money automatically going to the content owner.

Please note YouTube isn’t able to mediate rights ownership disputes. The platform only do remove the content as required by the law when receiving a complete and valid takedown notice. It’s up to the parties involved to resolve the issue.

On the other hand, It is frustrating to come upon that your content is uploaded to other channels without your permission and it’s time-consuming to manually search for these re-uploads.

On July 11, 2018, YouTube announces to introduce a new Copyright Match tool to help creators sniff out re-uploads of their contents on other channels. To start with, the tool will be made available to creators with a large number of subscribers (over 100,000).

Here’s how it works: when creators upload an original video to YouTube, the tool will begin scanning all the videos that are uploaded after it to find any are identical or nearly identical and surface them to you for review. Cases are included where the audio may be replaced or dubbed. Please make sure you are the first to upload the content to YouTube as a public video, as the time of upload is the deciding factor YouTube use to judge who should see match results.

Those match results will appear under a match tab, and creators are provided three choice: neglect and take no action, contact the creators who uploaded the duplicate videos or use YouTube’s copyright webform to send a video removal request. Before taking action, you’d better carefully evaluate each match to confirm that you own the rights to the matched content and ensure that you believe it infringes on your copyright. You should also consider whether the duplicate is classified to fair use or could be subject to some other exception to copyright and hence not require permission for reuse.

Please take note this tool only able to tell who uploaded a video first, not who owns it or has permission to upload it.
