## Description

Muxarr bulk-strips unwanted audio and subtitle tracks from your media library by remuxing (no re-encode, no quality loss), with Sonarr/Radarr integration to keep each title's original language. Dropping spare audio tracks often reclaims 10-30% of a file, and a 4GB file still processes in about a minute even on a NAS. Under the hood it uses mkvmerge for Matroska and ffmpeg stream-copy for MP4-family containers, and validates the remuxed output before replacing the original, so a failed run leaves your source untouched. New imports can be auto-processed via webhook, and per-directory profiles let different folders (anime vs movies, say) follow different rules. It also applies language priority and per-language track limits, and cleans up encoder/codec junk in track metadata with mkvpropedit without a remux.

## Common questions

### Does Muxarr re-encode video or audio when cleaning tracks?

No, Muxarr copies the video and audio unchanged and leaves out only the selected tracks.

### What happens if validation fails while remuxing a file?

Muxarr validates the output file before replacing the original, so a failed run leaves the source untouched.

### Can Muxarr process Sonarr and Radarr imports automatically?

Yes, it supports webhooks to process new imports as they arrive, with a configurable delay so tools like Bazarr can finish first.

### Which media container types does Muxarr support?

It supports Matroska files such as .mkv and .webm, plus MP4-family files such as .mp4 and .m4v.

### Can different folders follow different language and track rules?

Yes, per-directory profiles let different folders, such as anime versus western media, follow different language and track rules.

### What notification services can Muxarr use?

It supports Apprise, Discord, Gotify, Ntfy, Pushover, Slack, and Telegram, plus library rescans for Plex and Emby.
