Twitch has made some changes today. Some were pretty boring. Another, however, has a lot of people very upset.

The streaming giant has implemented audio monitoring tools similar to those used by YouTube, aimed at identifying the use of copyrighted music in archived copies of user's videos. The software will scan 30-minute sections of videos; if any unauthorised music use is detected within that block, the entire 30 minutes will be muted, even if music was only playing for ten seconds (the video itself will remain).

There's one very important caveat, though: this only applies to video-on-demand content, not live broadcasts.


Still, people are not happy, with either the move itself or the heavy-handed way it silences content. Seems that in addition to looking for music that's been overlaid, the software is also flagging the ambient and background music of the games people are actually playing.

Even major games are reeling; League of Legends' Twitter account has spent much of the afternoon sourcing alternate sources of music for users.

The monitoring has already kicked in. And, hilariously, has already silenced archived copies of Twitch's own programs.

If you think you'll be affected, you can read the fine print of the announcement over on Twitch.
