It’s been about a year since our last AMA. A lot has happened since Twitch started three years ago, and there have been some big changes this week especially. We figured it would be a good time to check in again.

For reference, here are the last two AMAs:

Note: We cannot comment on acquisition rumors, but ask me anything else and I’m happy to answer.

Proof: Hi reddit!

EDIT: Thanks for all the questions. I want to summarize a bunch the answers to a bunch of questions I've seen repeatedly.

1) Live streaming on Twitch: We have no intention whatsoever of bringing audio-recognition to live streams on Twitch. This is a VOD-only change for Twitch.

2) In-game music: We have zero intention of flagging original in-game music. We do intend to flag copyrighted in-game music that's in Audible Magic's database. (This was unclear in the blog post, my apologies). In the cases where in-game music is being flagged incorrectly, we are working on a resolution and should have one soon. False positive flags will be unmuted.

For context, audio-recognition currently impacts approximately 2% of video views on Twitch (~10% of views are on VODs and ~20% of VODs are impacted at all). The vast majority of the flags appear to be correct according to our testing, though the mistakes are obviously very prominent.

3) Lack of communication ahead of time: This was our bad. I'm glad we communicated the change to VOD storage policy in advance, giving us a chance to address issues we missed like 2-hour highlights for speedrunners before the change went into effect. I'm not so glad we failed on communicating the audio-recognition change in advance, and wish we'd posted about it before it went into effect. That way we could have gotten community feedback first as we're doing now after the fact.

4) Long highlights for speedruns: This is a specific use case for highlights that we missed in our review process. We will be addressing the issue to support the use-case. This kind of thing is exactly why you share your plans in advance, so that you can make changes before policies go into effect.


If you know of a specific VOD that you feel has been flagged in error, please report it to [email protected]. To date we have received a total of 13 links to VODs. Given the size of this response, I expect there are probably a few more we've missed, but we can't find them if you don't tell us about them! We want to make the system more accurate, please give us a hand.


5) 30 minute resolution for muting: Right now we mute the entire 30 minute chunk when a match occurs. In the future we'd like to improve the resolution further, and are working with Audible Magic to make this possible.

6) What are we doing to help small streamers get noticed? This is one of thing that host mode is trying to address, enabling large broadcasters to help promote smaller ones. We also want to improve recommendations and other discovery for small broadcasters, and we think experiments like our CS:GO directory point towards a way to do that by allowing new sorts and filters to the directory.


I have to go. Look for a follow-up blog post soon with updates on changes we're making.

Will automatic muting be applied to the Twitch chat whenever the chorus to Sandstorm is typed out?
