Assuming you are asking whether such conduct is unlawful, the answer is yes. It is a violation of California Penal Code section 632 to record someone's voice when they are unaware of the recording. It is not only a misdemeanor, but violation of the Code allows the victim to seek a civil penalty of $5,000 for each recording made in violation of the Code.
If you are a woman, depending on other factors, this may also be a violation of the criminal law related to taking pictures by hidden camera in an attempt to capture pictures up a woman's skirt, which can carry far greater criminal penalties.
Good luck to you.
