Learn how brands like Netflix, Mastercard, and Envato use sound and voice to stand out. Actionable strategies for rookies and experts to craft a cohesive brand identity.

What is Sonic Identity?

Sonic identity refers to the curated sounds (music, voice, tones) that represent a brand. It includes audio logos, jingles, voiceovers, and even UI sounds.

Example: Netflix’s “ta-dum” intro sound instantly signals its brand.

Example: Mailchimp’s friendly, quirky tone in emails and ads.
