Defining the Sound of a TikTok-First Audio Experience

iHeart TikTok Radio is a collaboration between iHeartMedia and TikTok, designed to translate the culture, behaviour and trends of the platform into an audio-first experience. ON THE SLY was commissioned to develop the sonic identity for the station, creating the audio assets and sonic framework that define how TikTok Radio sounds across the platform.

Designed around the idea of “your playlist meets your For You feed”, the station explores how TikTok translates when audiences put down their phones and continue the experience through audio.

ON THE SLY created the launch package for the station and continues to deliver ongoing branded audio assets, with new content produced on a rolling basis to reflect the pace of trends, creators and culture across the platform.

Creating a Sonic Identity for a Different Audience

Traditional radio imaging has evolved around the conventions of broadcast radio. TikTok Radio presented a different challenge.

The project began with a simple question:

How do you create an audio product that feels native to TikTok rather than traditional radio?

Rather than drawing inspiration from broadcast formats, the creative approach looked to the platform itself. The speed of content, emerging trends, creator culture, familiar sounds, social behaviours and constantly evolving conversations all informed the direction of the sonic identity.

The challenge was to create an audio experience that felt at home in the TikTok ecosystem. Every asset needed to reflect the pace, personality and energy of the platform while still functioning as a coherent audio brand.

Translating Platform Culture into Audio

Working closely with the iHeart TikTok Radio programming team, ON THE SLY developed a large library of branded audio assets designed to evolve alongside the station.

The sound was built to feel fast-moving, contemporary and culturally aware, drawing influence from the way audiences already engage with content across TikTok. New assets are delivered on an ongoing basis, allowing the station to evolve alongside trends, creators and conversations as they emerge.

The station’s sonic identity sits closer to creator culture and platform behaviour than traditional broadcast radio, reflecting the way audiences move through the TikTok ecosystem.

This project forms part of ON THE SLY’s wider work developing station sound, audio branding and sonic identities for major broadcasters and media brands internationally.
