What is an AAC file?

AAC (Advanced Audio Codec) is a more efficient audio compression format than MP3, offering better sound quality while taking up less storage. It is widely used in streaming, Apple devices, and mobile platforms. AAC supports multiple profiles, making it suitable for various applications, including low-bitrate audio transmission and high-fidelity audio playback.

How to open and play an AAC file?

AAC files can be opened and played using various tools. The most popular choices include [iTunes](https://www.apple.com/itunes/), [VLC](https://www.videolan.org/), [Winamp](https://www.winamp.com/), and [Foobar2000](https://www.foobar2000.org/). These tools support not only AAC files but also a wide range of other audio formats. Most modern media players also have built-in support for AAC files. On Windows and macOS systems, you can also use built-in media players to play AAC files. On Linux systems, the `ffplay` command-line tool (part of FFmpeg) can be used to play AAC files. Regardless of the tool you choose, the process is straightforward: simply double-click the file or right-click and select 'Open'. If you need to convert an AAC file to another format, FFmpeg provides powerful command-line tools, such as `ffmpeg -i input.aac output.mp3`.
