It is supported by media players like VLC, Windows Media Player, and editing tools such as Audacity and Adobe Audition. The format uses perceptual coding to reduce file size while maintaining high-quality audio, supporting up to 5.1-channel surround sound and offering features like dynamic range compression and metadata for playback customization.

It is widely supported by platforms like iTunes, YouTube, and Android devices, and can be created or edited using tools like Audacity, FFmpeg, and Adobe Audition. The format uses advanced compression techniques, such as perceptual noise shaping and temporal noise shaping, to optimize audio quality while maintaining efficient file sizes, and it supports multiple channels for surround sound and metadata for enhanced functionality.
