Frequently asked questions
What audio format will I get from the extracted track?+
Stream-copy extracts the audio exactly as encoded in the source container. An MP4 with AAC audio produces an .aac or .m4a file. An MKV with AC-3 audio produces an .ac3 file. An MP4 with MP3 audio produces an .mp3 file. If you need a specific output format (e.g. WAV regardless of source), enable the re-encode option and select the target format — this re-encodes the audio but allows format selection.
Why is my extracted audio out of sync when I add it back to a video?+
Extracted audio from a stream-copy operation preserves its original timing, including any initial delay (playback offset) that was set in the container. If the audio plays back with a delay or ahead of video when imported into an editor, adjust the audio offset. In some containers, audio tracks have an inherent delay value — editors respect this; manual import tools may not.
Can I extract audio from a video with multiple audio tracks?+
Yes — JAD lists all audio streams in the video (by language, track index, or codec) and lets you select which to extract. Common cases include MKV files with multiple language dubs or commentary tracks, and broadcast TS files with multiple audio programmes. Select the target track before extraction.
