After a modest academic career, Kuldeep left his home in Delhi and came to Bombay towards the end of 1943. Producer Rai Bahadur Chunilal, the then chief of Filmistan Studios, happened to be a friend of his father and took him as an apprentice in his sound department.

Kuldeep Singh won the Filmfare award for the Best Sound Recording for 1961 for his deft handling of the soundtrack of the film Junglee (1961).
