Making of MP3 from a video file is usually referred to as 'How-to Geek.' However, the first thing we need to ask ourselves is, what is an audio file? Before answering this question, there is a need to differentiate between an audio file with a video. MP3, which is the short name for MPEG-1 Audio Layer 3, is one of the two early 1990s format standards considered for MPEG audio. The particular format was given this accolade by Germany's Institute for Broadcast Technology, French research Institute CCETT, and the electronic firm Philips because of their simplicity, computational efficiency besides being error-free.

MPEG-4 Part 14, easily abbreviated as MP4, is an Apple's QuickTime (MOV) format technology, which has added support for other MPEG features. It is crucial to note that MP4 and MP3 fundamentally differ in the types of data the two formats store. Notably, MP4 files can store video, text, subtitles, still images, and audio, whereas MP3 files only store audio. This phenomenon can be referenced merely as, audio coding format for MP3 while MP4 is a digital multimedia container format. MP4 is essentially a file format containing a collection of compressed data. The details of how data is encoded are not the business of MP4 but how to store data in the container itself is the primary interest. Though the MP3 format may sound inferior, it is a technology that is likely to last long as it is considered the de facto standard for music streaming platforms, digital audio players, and music software. Interestingly, regardless of the device or the operating software you have, the MP3 format will most likely work for you.

As mentioned earlier, MP4 videos use high compression, making their file sizes much smaller than other video formats. This compression does not affect the quality of the video file. Since compression ensures the preservation of original quality, MP4s are usually network-friendly and also portable. Below are some of the ways to make Audio Files from Videos.

1. Extraction using the Audio Extractor

This is the best way to extract an audio clip from a video. It’s not only a fast way of extraction but also accurate and efficient. It is easy to extract audio from a video. This extraction has been made even easier by using free software, which strips the audio and then converts it to a choice format in seconds. Technically, video files consist of three parts: the audio, the wrapper, and the video. Most people or users are only aware of or familiar with the wrapper segment of the video file. The wrapper part of the file takes the format .MP4, MKV, .AVI, among other expressions.

2. Use of the QuickTime for Mac Users

Another great way of extracting an audio file from a video is using the quicktime for Mack users. It's as simple as clicking the video file in Quick Time, exporting it, and saving it as an audio file in a matter of minutes.

3. Conversion by use of a VLC Media Player

The media player conversion is not as fast and straightforward as the Quicktime for Mac Users and the audio extractor. It works well with Windows users because it has built-in software that allows the separation of audio from the video file. It has a longer process as below;

  • i. Go to Media and click Convert.
  • ii. Once the dialog box appears, add the video you wish to convert-you can show more options to select the timeline of choice for the audio file and save the changes.
  • iii. Select the conversion options, which could be OGG or Mp3, which is the expected output.
  • iv. Click the wrench icon and name the new audio file and click save note that this is an essential procedure that should not be missed.
  • v. Save the produced file to a destination of choice.

Alternatively, use an online converter to convert MP4 to Mp3 using Windows or other OS. This will extract audio files that are of high quality and it is absolutely free to download it online, and produce original quality. It’s as simple as that. The audio can be used on phones, car sound systems, music player among others. It has the capability of converting thousands of Mp4 files in a matter of minutes.

In simple terms, a binary system is an alternative system from the numerical mathematical counts that represent a combination of counting two numerals, for instance, (0) and (1). It represents the numbers 1 to 9.

When it comes to the computer system, the binary system's use easily manipulates all data and helps in effectively storing the same. The data can be informed of graphics, numbers, videos, and music, and words altogether.

When using the binary system, it becomes easy to use them in comparison to the decimal system. As such, computers can manipulate the information that has been fed to make it have an easy definition.

As we get on board in understanding the importance of the binary system in Computing, it’s important to understand how it works.

Since the numbers 0 and 1 do not have any symbols and, as such, represented by ten (10) you only have the option to count ONLY 0 and 1. This trend continues to units such as fours, eights, sixteens, thirty-twos, and the list continues. The number 0s and 1s in the binary system will, in this instance, is represented by Off and On. This can also be explained as the process by which the electrical signal is turned off and on again, but the fact remains that there must be base 2 exponents.

With this explanation, it’s now easy to get to understand the importance of using the binary system in Computing;

  1. Computer systems are not able to use the decimal numbers in their operations. In human beings' daily lives, we can use decimal number systems to manipulate figures and store any information. This is not so for computers. They represent the numbers by use of the lowest base number that we use manually. This number is two and hence use of) and 1, and 0, and the binary system is formed. On the other hand, computers use voltages, and the voltages are measures as a two-state system that we have previously described as electrical signals that is either on or off. Since computing operations cannot manipulate decimals, then using a binary system is easier and effective.
  2. As said, computers use a binary system, which is a two-state system. This is a system that has suited well in optical and magnetic storage components in the computers. The current world demands that all information is stored for future use or reference, and if decimal numbers were used, then there would be thousands of rules that would be put in place for the computers to work effectively. But with the binary system, all this is sorted within a fraction of a minute. Again the maximum rules required for a binary system to operate and carry out the calculations are only four; this is awesome in the digital world.

This leaves us with a question, how to convert Binary to decimal Numbers;

With a Binary system, the two different digits, 0 and 1, can store any of the two levels of information depending on the control signal. Usually, the higher level takes charge of value 1, and the lower level takes up the value 0. This gives the binary system process.

Below is a step by step process by which a Decimal is converted to Binary

  • Step1: Dividing the decimal number by 2. After dividing, assig a value R1=remainder and Q1= the amount obtained from dividing the decimal.
  • Step2: Divide Q1 with 2 and take note of the remainder. Allocate the remainder value to R2 and the value of the amount obtained to Q1.
  • Step 3: Repeat the sequence until you get to such a time that the final amount will be equal to 0. Step 4: The answer to the Binary number will have the formula R (n) (n-1)….. R3, R2, R1

When converting the value to the binary system, the only difference is the sequential arrangement, and therefore the need to understand how the binary system works.

How to Speed up your Website with next-generation Image Formats

Images form a larger part of information communication to the readers. But if not well managed, they could use the entire space available for storage and cause endless user experience challenges. To make them more presentable, they need to be resized for proper optimization. While this posed a big challenge to store such information, google came up with exceptional next generation image formats. The most popular ones are the Webp and the JPG2 formats. Webp and JPG2 are both modern image formats that can provide compressed images that are superior, smaller, and rich. They are 26% smaller in size in comparison to the PNGs

Web designers who have adopted these formats have found it easy to store thousands of compressed images in tiny storage space. Since images form an integral part of web design, it is important to look for a way to ensure that they are fully optimized. The website speed will as well improve without compromising quality altogether. Google has come up with some important suggestions to improve the speed, and below are some of the suggestions.

1. Automation of Image compression There are two major ways by which images can be optimized for speed. These include compressing the files and reducing their size. Compression is one of the easiest ways when the right tools are available. For instance, with a WordPress, its easy to install Imagify, and this will help in compression of the best part of the images at hand. This becomes an automatic compression tool even for future images that one would wish to add in the library.

2. Serve Images in Next-Gen Formats While the traditional methods of generating image formats could lose high quality, which relied on JPEG (lossy) and PNG (lossless compression), the current formats can create fast load speeds, and the files can retain the metadata. On the same note, quality is maintained as the original in comparison to the traditional formats. Some of the recommended next-generation image formats to give such solutions include the JPEG 2000, JPEG XR, and the Webp. 3. Responsible use of Images Among the essential tips that every designer ought to adopt is to use minimalistic design, and it will provide greater user performance. Photographers can use several leverage alternatives for greater user experience. Among them include;

  • Using embedded videos rather than the bulky GIFs.
  • Use CSS3 to generate alternative image elements.
  • By using scalable graphics that use simple designs and logos.

While these methods can be applied, critical path rendering such as caching, minifying, and compressing all the page resources will optimize the images from back to back. With these amazing tips, it's important to remember that images are first collected from a JPG and later converted to Webp to ensure proper optimization. For excellent results, there is a step-by-step instruction used to convert JPG to Webp.

Steps to convert JPG to Webp

  • Step 1: Use the free JPG to Webp Image Converter and convert any JPG image to Webp by clicking the submit button available
  • Step 2: As soon as the conversion is complete, you will be redirected to the download page.
  • Step 3: A download button will appear. Click the button, and the uploaded files will be downloaded while already converted into the Webp format.

Some of the benefits of converting to Webp images include;

  • High-quality images- Since this format uses the latest programs, the results achieved will be of high quality.
  • This is a format that has a unique collection of files and images.
  • It's highly confidential that all converted files are deleted from the server as soon as the conversion is done.
