AAC

AAC (Advanced Audio Codec) is a lossy digital audio compression format that offers better sound quality than MP3 at similar bit rates. Widely used for music streaming and storage, AAC is supported by most devices and platforms, including iTunes and YouTube. Its efficiency makes it a preferred choice for audio encoding, delivering high-fidelity sound in smaller file sizes, perfect for audiophiles and casual listeners alike.

GSM

GSM files are used primarily for audio compression in mobile devices, specifically for storing voice data with high efficiency. This lossy compression format offers a reduced file size while maintaining reasonable audio quality, making it ideal for telecommunication applications. Understanding GSM can aid in audio encoding for voice recording and communication tasks.
