The AAC to M4A Converter Tool is a simple utility for packaging a raw AAC audio stream into a standard M4A container. While a `.aac` file contains only the audio data, an `.m4a` file is a proper container that includes metadata and is recognized by all modern players, especially Apple devices. This conversion ensures your AAC audio is playable everywhere.

• Ensure Playback Compatibility: Convert a raw `.aac` stream into a playable `.m4a` file.
• No Quality Loss: The process simply wraps the existing audio in a new container without re-compressing it (unless filters are applied).
