Free Trial Offer

Free Trial Offer is a generative, evolving sound-scape created with audio samples from American pharmaceutical advertisements. The US is one of the only countries where direct-to-consumer advertising of prescription drugs is legal. (New Zealand is the other)

The audio is generated using a context-free grammar — a set of rules how the samples should be replaced as the piece progresses, thus continuously evolving and changing while maintaining a core structure. The library of samples was created by manually selecting chunks of audio from various ads found on YouTube. The structure and ordering was established through several iterations of testing and experimenting. Detailed documentation on the process can be found here.
