- Description
- An M4A file is an audio file created in the MPEG-4 format, a multimedia container format used to store compressed audio and video data. It contains audio encoded with either the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC).
- ICML (Adobe InCopy Markup Language) is an XML-based file format used to exchange document content and formatting between Adobe InDesign and InCopy. It preserves text, styles, and layout information so that writers and editors using InCopy can work on content linked to an InDesign layout. It is commonly used in publishing workflows for collaborative editing of page layouts.
