Watch the last three seconds of your brand's latest video. The logo comes up, maybe a URL, maybe a tagline. And what do you hear?
I've done this with a lot of brands by now, and the answer is usually one of three things. Silence. The library track just stopping, mid-bar, because the edit ran out. Or a fade so quick it sounds like somebody tripped over the cable.
That's a shame, because those three seconds are the most valuable bit of the whole video. It's the one moment where everybody knows who's talking.
Why it keeps happening
Nobody plans it badly on purpose. The music gets picked late, usually by the editor, usually with a deadline in the room. The track was written as a three minute song, not as a 30 second spot, so it doesn't have an ending that fits. The editor does what they can. Somebody approves the grade, the colours look great, and the sound at the end just... stops.
And then it happens again on the next video. And the one after that. So the brand ends every film in a slightly different way, and none of those endings sound like the brand.
What a sound logo actually does there
A sonic logo is basically a full stop you can hear. Two to five seconds, the same every time, sitting exactly where your visual logo sits. It closes the film properly, and because it's the same every time, people start to link it to you. Not after one play. After twenty, thirty, fifty.
That's the bit people underestimate. A campaign track is spent the day the campaign ends. A sound logo gets a little more valuable every time it plays, because recognition builds up with every exposure.
It also fixes the practical problem. If your sound logo lives in the same key as the music under it, the ending lands instead of clashing. Editors stop having to invent an ending under pressure, they just drop it in.
Try this before your next meeting
Line up your last ten videos and skip straight to the end of each one. You're only listening now, so close your eyes if it helps, and ask yourself two things:
Does the music end on the beat, or does it get chopped off?
Would anyone recognise these ten endings as the same company with their eyes closed?
If the answer to the second one is no, you've got your reason. You don't need research to convince the room. Ten endings that disagree with each other do that on their own.
Where to start
You don't need a whole audio identity to fix this. Most brands start with the sound logo, because it's small, it's quick, and you'll hear it everywhere within weeks. The rest (an anthem, UX sounds, guidelines) can grow from it later.
If you want a second pair of ears on those ten endings, send them over. Our free sonic brand quickscan does exactly this, and in two weeks you'll know how your brand sounds right now.
