The 18 Best Tools to Convert AAC to MP3 and MP3 to AAC

AAC is an audio file format, just like mp3. AAC is much better than mp3 in size and quality. It is excellent for audio output and can incorporate more data clearly than mp3. It is better to store your audio data in AAC format rather than mp3. This article will explain everything to know about the AAC file format, convert it from mp3, convert AAC to mp3, and other essential bits. So let us get started.

What is MP3?

MP3, which is formally known as MPEG-1 Audio Layer III or MPEG-2 Audio Layer III, is a digital audio format coding. MP3 or mp3 is commonly used in various media and is one of the most popular audio formats. This audio codec was released in 1993. It is ISO and IEC certified file format and is an open file format. So, it is free to use and is not patented by anyone particular.

MP3 is the most popular for its use in music. It is supported by almost every device, and it holds lossy audio in small file size compared to some other audio formats.

What is AAC?

Before anything, let us learn what is AAC? AAC stands for Advanced Audio Coding. Well, AAC is an audio coding standard for lossy audio compression. It was introduced as the successor of the mp3 file format. AAc was first available for public use in 1997. This file format has been standardized by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) as part of the MPEG-2 and MPEG-4. AAC file supports up to 96 kHz audio channel data in one stream.

AAC is used in many devices and media. iTunes and the iPod have been using AAC since 2003. Some devices that use AAC are, Nintendo DSi, Walkman, Samsung YEPP, Philips GoGear Muse, etc. many of the Apple, Sony, and Blackberry mobiles also use AAC for their device audio output.

How to Open an AAC File?

Nowadays, almost every media player can open and run AAC files. But if you are having problems with opening an AAC file, then try using the VLC player. VLC players can run AAC files smoothly.

One more thing you can try is to open it on a gaming console. As AAC is mainly a gaming audio file, it will run on Playstation or Nintendo Wii.

Difference Between AAC and MP3

  • The AAC (Advanced Audio Coding) was designed to be better than the MP3 (MPEG – 1 Audio Layer 3) file format. AAC (from 8 kHz to 96 kHz) supports more sample frequencies than MP3 (16 kHz to 48 kHz).
  • AAC is much better in handling audio frequencies that are above 16 kHz.
  • MP3 supports up to 2 channels in MPEG-1 and 5.1 channels in MPEG-2 whereas, AAC supports 48 channels.
  • AAC uses a pure MDCT, which in result produces a highly efficient and more simple filter bank.
  • AAC has a more flexible joint stereo sound output than mp3.
  • There is no licensing requirement or patenting the AAC file format when you use it for stream or distribution content. On the other hand, Sisvel, Texas MP3 Technologies, Fraunhofer IIS, Alcatel-Lucent, and Thomson have claimed legal control of relevant mp3 patents.
  • And finally, AAC offers better and more refined audio quality than an MP3 file format.
