What Is MP3

MP3, previously known as MPEG-1 Audio Layer 3 or MPEG-2 Audio Layer 3, is one of the most popular coding formats for digital audio. You can find MP3 files everywhere nowadays.

  • MP3 was created by the Moving Pictures Experts Group (MPEG) and was first defined as the third audio format of the MPEG-1 standard.
  • Then, MP3 was kept and been extended further to be the third audio format of the MPEG-2 standard: it defines the additional bit-rates and gives support for more audio channels.
  • The third version is known as MPEG 2.5; it can support lower bit rates in a better way. But this is not a world-recognized standard.

MP3

MP3 uses a lossy data-compression algorithm to encode data. You can find a large reduction in file sizes when compared to other uncompressed audio formats due to the using of inexact approximations and the partial discarding of data. Though the file size is reduced a lot, the fidelity of MP3 files is still acceptable. That finally contributes to a boom in the distribution of music over the Internet in the mid-to-late-1990s. Later, with the fast development of portable media players and smartphones, MP3 is at the height of its popularity.

The extension of an MP3 file is .mp3; you can change it to another audio format like AAC and WAV easily. Besides, you can also convert MP3 to a video format like AVI if you need it.

Advantages of MP3 Format

  • Reduced file size: small size is one of the most outstanding features of MP3. The size of a 3-minute lossless audio file (like WAV) can be up to 30 MB, while the size of a 3-minute MP3 file maybe around 3 MB, only one-tenth of the uncompressed audio. This allows users to rip a large number of music files on one disc. (How to recover lost music files?)
  • Acceptable quality: though the MP3 file size is greatly reduced compared to the uncompressed formats, there isn't a noticeable loss in its quality. It only removes the parts of the audio file that human ears can barely hear - the highest and lowest ends.
  • Not fixed compression ratio & bit rate: users can compress the audio file to the desired size by choosing a preferred compression ratio or bit rate.
  • Strong compatibility: the MP3 file format is supported by most platforms, systems, and applications, and it can be shared easily & upload/download quickly due to the small size.

Limitations of MP3 Format

  • Quality loss: though the loss of quality in MP3 audio is not noticeable to common users, you still can’t ignore it in some special cases. Besides, it includes the compression artifacts or noises that are not present in the original audio recording.
  • Copyright: the popularity of the MP3 format boosts both virtual and physical piracy. Cheaper or even free duplicate versions of MP3 music files can be purchased or downloaded easily from the internet. This does bring bad effects on copyright.
  • Data loss: MP3 files can be easily attacked by viruses or malware during the uploading, downloading, or file sharing process. (What are the best file hosting services?)
  • AAC successor: MP3 can be replaced by the Advanced Audio Coding (AAC) format, which achieves better sound quality at the same bit rate.

What Is AVI

The full name of AVI is Audio Video Interleaved; it is a multimedia container format introduced by Microsoft in November 1992 as a standard video format for Windows software. AVI supports synchronous audio-with-video playback since it can contain both audio data and video data. AVI is developed on the basis of Resource Interchange File Format (RIFF), which divides file data into blocks/chunks and is used as a container format for storing multimedia data.

  • In February 1996, Matrox OpenDML group developed some file format extensions and many AVI files used them. Microsoft gave support to those AVI files and called them AVI 2.0, unofficially.
  • Later in 2010, AVI was considered as the official wrapper by the US government's National Archives and Records Administration for keeping digital video.
