Audio File Formats - INI
Audio file formats are standard specifications for storing, compressing, and playing digital audio data. They are classified into three main categories: uncompressed formats (such as WAV), lossless compression formats (such as FLAC), and lossy compression formats (such as MP3 and AAC), each with trade-offs between sound quality, file size, and compatibility. Appropriate formats are selected depending on the application, such as music distribution, professional recording and editing, and game audio.
