Understanding Codecs:
To comprehend LDAC better, let's delve into what codecs are. Codecs are compression technologies designed to reduce the size of large files, comprising an encoder to compress files and a decoder to decompress them. Codecs can compress data (PKZIP), static images (JPEG, GIF, PNG), audio (MP3, AAC), and video (Cinepak, MPEG-2, H.264, VP8).
