About this sound

Deep metallic Reaper horn blast from Mass Effect 3, used for dramatic reveals, looming threats and sci-fi horror moments in edits and memes.

This is the deep, distorted horn blast of a Reaper from Mass Effect 3, a low metallic roar that builds into a harsh, vibrating bellow. It does not sound like a normal horn at all, more like a giant machine waking up and warning everything nearby. The sheer weight and dread in the tone make a scene feel instantly bigger and more dangerous, which is why editors use it to turn an ordinary entrance or reveal into something apocalyptic and unstoppable.

Pro tip

Place the horn right on the cut as something huge enters frame, let the full five seconds ring out without music underneath, and lower dialogue completely. Do not loop it or use it for small jokes, the impact comes from one isolated blast.

How people use it

Reveal a boss enemy entering a game montage.
Punctuate a dramatic zoom on something unexpectedly huge.
Open a sci-fi trailer edit with looming dread.
Meme a pet appearing like an unstoppable threat.

More information

In Mass Effect 3, released in 2012 by BioWare, the Reapers arrive as colossal sentient starships invading Earth, and their horn became the audio signature of that invasion. Players heard it whenever a Reaper landed or fired, so the sound quickly left the game and spread through trailers, remixes and meme edits online. It is often compared to the Inception Button for the same deep braam effect, but the Reaper version is harsher and more alien, which keeps it popular for parody reveals and genuine horror tension alike.

FAQ

What is the Reaper horn sound?

The Reaper horn is the deep metallic blast made by the Reapers, the giant sentient machines in Mass Effect. In Mass Effect 3 it signals their arrival and attacks, creating instant dread with its low, distorted, vibrating roar.

Why do editors use the Reaper horn in videos?

Editors use it because a single blast instantly makes anything feel massive and threatening. It works for serious sci-fi and horror edits, and equally well for comedy when a tiny pet or ordinary object is framed like a world ending threat.

Is this Reaper horn from Mass Effect 2 or 3?

This version is catalogued as the Mass Effect 3 Reaper horn, from the Reaper invasion that opens and drives that game. Earlier games introduced the Reapers, but the distinctive landing and combat horn heard here is most associated with the third entry.
