for ambitious blind filmmakers
Cassette empowers blind and visually impaired creators to craft immersive audio films using sound effects, music, and dialogue. No visuals, no barriers—just pure storytelling through sound.
This guide provides detailed, step-by-step instructions to help you navigate and utilize the application effectively.
Cassette currently offers the ability to select music and sound effects through integration with the Freesound API. Users can generate dialogue using a built-in text-to-speech engine and play back their scripts using the Web Speech API, which supports a limited selection of accents for added expressiveness.
We’re excited to support your creativity through sound.
This project is inspired by the front desk office assistant at California School for the Blind, Marcus Graves.
