What Is an AAC Format-Things You Definitely Shouldn't Miss

by Kayla Morrison • 2024-01-11 10:27:09 • Proven solutions

Gone are the old days when MP3 was the widely used audio format. Today, many multimedia players support standard audio formats like AAC, AU, FLAC, M4A, and more. In fact, Apple uses AAC as its default audio format for streaming and downloading music from iTunes and Apple Music. So this article wants us to learn what is AAC format and how to convert it to any audio format.

Part 1. What Is an AAC Format-Basic General Knowledge Questions 2022

AAC (Advanced Audio Coding) is a lossy audio format that was designed by Sony, Nokia, Panasonic, LG, NEC, Dolby, and Bell in 1997. It was initially intended to be a successor to the accessible MP3 format. AAC includes at least 48 full-bandwidth (up to 96kHz) channels in a single stream and another 15+ low-frequency effects.

Currently, you can open AAC files on Nokia devices, Android, BlackBerry, iPod, iPad, iPhone, iTunes, Wii, PSP, and more. At a similar bitrate, you're likely to get better audio quality with AAC than on MP3. However, some media players such as the Windows Media Player and PS3 don't support AAC format. In simple terms, AAC has limited hardware support. So, converting AAC to another universal audio format like MP3 is the best solution.

Part 2. Best Way to Convert AAC with UniConverter

It's an open secret that Wondershare UniConverter is the best file converter currently. It is lightweight, super-fast, and easy to use, unlike most desktop converters with complicated user interfaces. Here, you can encode AAC to popular audio formats such as MP3, FLAC, WAV, WMA, more. It can also edit the audio channel, bitrate, sample rate, and encoder. And yes, the UniConverter can convert between videos as well.
