Snehil Chaddha began composing jingles in school and, by Class 12, set a record in the India Book of Records for creating the maximum number of jingles in 24 hours. Though a computer science student, he used his computer less for coding and more for mastering audio tools, designing sounds, and studying the craft that drew him toward films. Early ad projects with Civic Studios led him to Pocket FM, Kuku FM, and Headfone, where he designed audiobooks, promos, and ad campaigns for millions of listeners.

His film journey started with Lilly Chacha as music director, a feature that won multiple awards and reached lakhs of viewers on YouTube. He went on to work on two Telugu festival films, several international shorts, and more than five international festival films as a sound designer, while also composing for ad campaigns and background scores.

Beyond films, Snehil has been a personal sound designer for millionaires and entrepreneurs in Dubai, Bali, and other regions. His work also spans interactive media—composing soundtracks for video games on mobile and PC, creating gadget sounds, and developing unique sonic identities. Today, he runs his own production house focused on audio post-production, handling everything from ad edits to full-scale sound design for films, brands, and digital platforms.
