Audio metadata refers to the information embedded within an audio file that describes its content. This can include details such as the title, artist, album, genre, and track number. Metadata helps organize and identify audio files, making it easier for users to manage their music libraries and for software to display relevant information. In addition to basic details, audio metadata can also include technical information like bitrate, sample rate, and file format. This data is crucial for applications like music players and streaming services, as it enhances user experience by providing context and improving searchability of audio content.
