How to create audio branding

I recently posted a pair of quiz videos for viewers to guess the brand the audio represented.

It prompted a question: how is an audio brand created?

Here’s a few interesting pieces I found:

How Tostitos uses their products to create audio brand marks.

The music theory and the real world created some of Apple’s most iconic sounds.

A tutorial from Wikimedia on the strategy behind and the tools you can use to create an audio brand.

This piece from Wired goes into the semiotics that inform some famous branded sounds.

And lastly, this recent podcast from Planet Money dives into all the elements that create the iconic TikTok bumper sound.

What do you think? Are these pieces helpful?
