In recent years, the demand for dual audio releases has increased significantly, particularly in regions where English is not the primary language. Dual audio releases allow viewers to watch movies with subtitles or a secondary audio track in their native language.

Dual audio files contain multiple selectable audio tracks multiplexed into a single video container, typically an MKV (Matroska) file.

Specialized encoders use advanced video codecs to significantly shrink the file size while preserving as much visual and auditory detail as possible. Why Dual Audio Repacks Are Popular
