Convert AAC to WMA
About AAC
Advanced Audio Coding (AAC) was designed to be the successor to the MP3 format. It generally delivers higher-quality audio than MP3 at the same bitrate, especially at lower bitrates. AAC is the standard audio format for YouTube, Apple's iTunes, and is widely used on mobile devices and digital video broadcasting. It's a very efficient codec, but it is a patented technology, which has implications for its use in some open-source projects.
About WMA
Windows Media Audio (WMA) is a proprietary audio format developed by Microsoft. It was created to compete with the MP3 format and includes support for Digital Rights Management (DRM) to protect content from piracy. While it offers good compression and was once common, its popularity has significantly declined due to its proprietary nature and limited support outside of the Windows ecosystem. There are both lossy and lossless versions of WMA.

Frequently Asked Questions
Is AAC the same as M4A?
Not exactly. AAC is the audio encoding standard (the codec). M4A is a file extension for an audio file that is encoded with AAC. So, an .m4a file is a container, and the audio inside is typically AAC-encoded. Think of AAC as the engine and M4A as the car.
Which is better, AAC or MP3?
Most listening tests conclude that AAC produces better audio quality than MP3 at the same bitrate. This advantage is more pronounced at lower bitrates (e.g., 128kbps and below). For this reason, many streaming services have adopted AAC.
Should I still use WMA?
Generally, it is not recommended to use WMA for new audio files unless you have a specific need within the Windows ecosystem. Formats like MP3, AAC, and FLAC offer much broader compatibility across different devices and platforms.
How can I play WMA files on a Mac?
Mac computers do not natively support WMA files. To play them, you will need to use a third-party media player like VLC Media Player, which includes its own codecs for a wide variety of formats, including WMA.
