WAV files deliver uncompressed, lossless audio quality, making them ideal for professional editing and archiving. However, their large size makes them impractical for everyday use, streaming, or sharing. AAC (Advanced Audio Coding) solves this by offering smaller file sizes with near-lossless quality, perfect for mobile devices, online platforms, and storage efficiency.
