Teknik Detaylar

M4A files use the ISO Base Media File Format (ISOBMFF / MP4) container. Audio is typically AAC-LC encoded. ALAC variants provide lossless compression. The container supports chapters, metadata, and album artwork.

Gecmis

Apple adopted the .m4a extension to distinguish audio-only MPEG-4 files from video .mp4 files. iTunes Store launched with DRM-protected .m4p files in 2003 and shifted to DRM-free .m4a in 2009.
