MP3 refers to a coding format, which is formally known as MPEG-1 Audio Layer III, for digital audio. MP3 or mp3 designated files that contain a basic stream of MPEG-2 Audio or MPEG-1 Audio data, which is encoded. They don't have other complexities of the format. Let's find out more about MP3 file format and the advantages it offers.
As far as audio compression is concerned, MP3 is a lossy compression type for encoding data with the help of partial discarding and inexact approximations of data. And this results in a great reduction in the file size unlike uncompressed audio.
The small size and great audio quality resulted in an incredible spread of music files on the Internet in the 90s. MP3 served as a great technology as storage and bandwidth were quite expensive in those days.
In a few years, MP3 format faced controversies regarding music piracy and copyright infringement. Aside from this, the introduction of portable media players, including smartphones, this file format became universal.
So, how does this compression work? This compression reduces the accuracy of specific parts of sound that humans are not capable of hearing. Typically, this method is called perceptual coding or psychoacoustic modeling.
Then the rest of audio information is recorded with the purpose of saving space. This is done using FFT and MDCT algorithms. Unlike CD-quality audio, this type of audio compression can help reduce the size of the file by up to 95%. For instance, if you record a conversion at a fixed bit rate of 128kb/s, the file size will be only 9% of the original CD audio.
Advantages of MP3
Now, let's take a look at some of the advantages offered by the MP3 audio file format. Based on these advantages, you can decide if you should go with this format or opt for a lossless option.
One of the primary advantages of this file format is that it allows you to record songs, speeches or conversations for hours without compromising on a lot of storage space. Often, you can save up to 95% of storage space. And the great thing is that the audio quality is comparable to other formats that take up a lot of space.
The small size of these audio files allows you to save hundreds of thousands of files on a small memory card or memory stick. In other words, you can store more than 170 songs on a compact disk that has a storage capacity of 700MB. On the other hand, the CDDA option doesn't allow you to store more than 15 songs.
Aside from this, since the file size is quite small, you don't need to spend a lot of bandwidth even if you download hundreds of songs. Therefore, MP3 is a great choice for all types of users.
The beauty of MP3 is that it allows you to adjust the level of audio quality you need based on the available storage space. You can choose between 32kbps and 320kbps. However, keep in mind that the higher the bit rate, the higher the file size.
So, this was an introduction to MP3 file format and the advantages it offers.
