An AAC file is a highly efficient and modern format for storing audio data. Its intention is to improve on existing formats such as MP3 by introducing a more effective compression algorithm while at the same time preserving the quality of the original audio data.

This improved efficiency has meant the AAC format has become widely adopted within the fields of digital music, audio books, and other online audio services. The compression outperforms other comparable audio formats while providing similar quality at reduced bit rates.

The emergence of AAC as an alternative audio file format, along with its adoption by many big names in the industry, has meant support for the format in both the audio editing and playback arenas has gained significant traction.

MP3 files are a well-known file format for the storage and playback of music and digital audio. The MP3 format has been around for a long time and has become a standard format for music. Despite newer formats arriving, such as AAC, MP3 still remains the primary choice for digital music playback.

It's highly efficient compression methods allow what would otherwise be very large audio data to be compressed down to a fraction of its size with little noticeable difference in quality. The quality, or bit rate, can be specified from 96KB/s (low quality) to 320KB/s (high quality). Naturally, the higher the bit rate, the larger the final MP3 file.

MP3 files are synonymous with digital music and are therefore supported by all major audio and music editing and playback software. Major operating systems and platforms often have built-in support for the playback of MP3 files.
