With no credited artist, source work or original release attached to this clip, its history is online rather than in a film, game or show. The file circulates on soundboards under the name Free Line Intro1, shared as a free to use opening sound for creators who need a fast intro without building one themselves. That simple utility has kept it in use, passed between editors and streamers looking for a short line intro sound effect that can be dropped into almost any project without explanation.
关于此声音
A short free line intro sound effect lasting just over a second, used as a clean opening sting for videos, streams, podcasts and edits online.
This is a brief intro sound built to sit right at the start of a clip, lasting just over a second before it clears out. It has the tight, punchy feel of a line opening, giving a video or stream a clear starting point instead of a cold open. Because it is so short, it does not compete with speech or music that follows, it simply marks the transition into the main content. Viewers hear it as a signal that something is beginning, which makes even simple edits feel more deliberate and put together.
