AAC (Advanced Audio Coding)
AAC (Advanced Audio Coding) is a lossy digital audio compression standard that offers higher sound quality than MP3 at the same bit rate. This means that for the same file size, an AAC file can sound clearer and more detailed than an MP3 file. It’s standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications. AAC is widely used for streaming, digital radio, and on devices like smartphones and tablets.
Example:
AAC is the default audio format for Apple’s iTunes and iOS devices, ensuring high-quality playback while conserving bandwidth.
Key Features:
High Efficiency: Superior sound quality at lower bitrates compared to MP3 (e.g., 128 kbps AAC ≈ 192 kbps MP3).

Sampling Rates: 8 kHz to 96 kHz.
Bitrate Range: 8 kbps (low quality) to 320 kbps (high quality).
