Can a third party record a conversation without the consent of the other party?

The Invasion of Privacy Act ( 630 et seq.) prohibits one party to a conversation from recording it without the other's consent. ( Ribas v. Clark (1985) 38 Cal.3d 355, 360, 212 Cal.Rptr. 143, 696 P.2d 637.) While one "who imparts private information risks the betrayal of his confidence by the other party, a substantial distinction has been recognized between the secondhand repetition of the contents of a conversation and its simultaneous dissemination to an unannounced second auditor, whether that auditor be a person or mechanical device.
