What is an MP3

MP3 is one of the most popular audio file formats. This file format was created by Moving Pictures Expert Group, which is widely known as MPEG. In an MP3 file, you can discover a compression algorithm, which is capable of compressing the overall file size. Smaller file size is the main reason that contributed towards the popularity of the MP3 file format.

You can call MP3 a lossy file format. That’s because the compression used to create an MP3 file is irreversible. In other words, some data with related to the original file is lost during the conversion process. However, it is still possible to get decent quality output from MP3 format.

Back in the day, WAV was the most common file format that people used to store music. However, the WAV file format was quickly replaced with an MP3 file format. That’s mainly because of the compact size of the MP3 file format. For example, if you take a 4-minute song, it would be around 40MB in size in WAV format. However, the size would drop up to 4MB when you have it in MP3 format. Therefore, you will be able to experience a 90% reduction in size. Even if you are experiencing a 90% reduction in size, you will not have to worry about a significant reduction in the audio quality. You will still be able to experience near CD quality in an MP3 file.

When you can compress audio files, you will not come across the need to use a lot of storage space for storing the audio files. This is the main reason why people prefer to stick to the MP3 file format, instead of even taking a look at the other file formats available out there.

However, it is important to keep in mind that the bitrate of an MP3 file will be reduced. Bitrate refers to the amount of audio information that is available in the file for every second. This is usually measured in kilobits per second. If the bitrate is high, you can receive a better quality out of the audio files. However, the bitrate of an MP3 is reduced. That’s because the MP3 conversion process would remove some of the audio parts, which human ears cannot hear. In other words, the lowest ends and highest ends will be removed. This is the main reason why an average music listener will not be able to experience a significant change in quality when a WAV file is converted to MP3 format.
