Part 4: Brief Introduction to Common-used Audio Formats

Generally speaking, there are two main types of audio file formats, namely, lossy formats such as MP3, AAC, Opus, etc. and lossless formats such as WAV, FLAC, APE, etc. In simple terms, lossy compression is to achieve compression by removing some existing data in the high-frequency part of the data that has less impact on the human ear and lossless compression is achieved by optimizing the arrangement. Since there are so many kinds of audio formats, how should you decide when converting a video into an audio file? Here is a brief introduction to some common-used audio formats.

MP3: Among all audio formats, MP3 is the absolute mainstream. Audio files stored in this format can greatly reduce the amount of audio data and provide better sound quality. It is widely used, and convenient to store, carry and spread, especially for network listening, or stored in mobile phones to play MP3 music.

AAC: The full name of AAC file is Advanced Audio Coding. AAC file is also a lossy compression format, which uses a new algorithm for encoding that allows for a smaller file size without a significant reduction in sound quality. In terms of adoption, the biggest supporter of ACA encoding is Apple, with devices such as iPhones, iPads and AirPods, and much of the music in iTunes stored in this format. Although it is a great improvement over MP3, its application range is not as wide as MP3.

M4A: This format is most commonly used in Apple devices such as iPhone, iPad, etc. Although M4A is a compressed format, there is no loss of audio quality. In addition, it is not protected by digital rights management, so you have the flexibility to re-edit and transfer them. M4A files can be read perfectly in iTunes, iPod and other Apple devices. However, it is less compatible with other brands than MP3 format.

FLAC: FLAC is called Free Lossless Audio Codec, which is a lossless compression format. There is almost no loss of information in the audio data using this codec. Use a relatively high-end earphone and sound card to play it, you can hear very realistic and vivid music, but the file occupies a large space, so it is only suitable for storage in a computer or a large-capacity mobile phone.

Final Words

This passage has introduced you six methods to convert video files to audio, each with their own characteristics. The advantage of online converters lies in their convenience, but they can be annoyed by various ads, file size limits, etc. The last two YouTube video downloaders have the advantage of downloading and converting directly to the desired format, but they have a single function and the downloadable platform is limited to YouTube only. Any Video Converter seems to be a better choice. Although it needs to be downloaded to the desktop to work, the process is very fast and doesn't take much time. From a functional point of view, it is feature-rich and offers arguably the most diverse range of convertible formats. In addition, it supports adding not only local videos but also online videos, and it supports more platforms than just YouTube. The most important thing is that it is completely free. So, what are you waiting for, just download it and try it out!
