Completion of a new visual identity usually involves finishing touches such as finding a good sound signature to accompany the animation of the logotype.
A sound signature creates an instant audio connection between a brand and the customer (example: Nokia or iPhone sound signatures). We like them to be uniquely composed and recorded specifically for each brand but when the budget doesn't allow for this we have to turn to stock sounds, which can be appropriately adapted.
We love this quote by Amir El Kadi, a sound designer:
"Visual impressions rule our life yet it is sound that gives those pictures a soul."
