<![CDATA[The increasing availability of podcasts, video platforms, and digital media environments has transformed how learners encounter authentic linguistic input beyond traditional classroom settings. The study aims to explore how digital authentic materials function as an ecological system that supports listening comprehension, vocabulary development, and multimodal language learning. Using a systematic literature review, this research synthesizes approximately forty peer-reviewed studies retrieved from major academic databases, including Scopus, Web of Science, and ERIC, published between 2015 and 2026. The analysis employs thematic coding to identify patterns in the use of podcasts, video-based learning, and extramural digital exposure in SLA research. The findings reveal three dominant clusters: podcast-based listening exposure, video-mediated multimodal learning, and extramural digital engagement. These clusters collectively create an ecosystem of authentic language input that enhances vocabulary acquisition, listening proficiency, and communicative competence. The study proposes the Digital Authentic Materials Ecology (DAME) model, which conceptualizes digital learning environments as interconnected networks of authentic input. The findings suggest that integrating podcasts, online videos, and extramural digital resources can significantly enrich Arabic language learning by providing learners with sustained exposure to authentic linguistic and cultural discourse.]]>
