Voice recording is one of the main tasks of the BBRC. Conversations from different sources are recorded and can be found, displayed and listened to via an intuitive user interface. The recorded conversations are immediately available (even while the conversation is in progress), but can still be listened up to years later. The search function for conversations has extensive options which allow the user to find specific conversations even among millions of other conversations. The BBRC offers features which facilitate the analysis of recorded voice data, such as the ability to add comments at any point in a conversation timeline and the ability to filter out interference frequencies.
Recorded data can also be analyzed offline, by generating and saving analysis packages. This function can be used to transfer call data to authorities.
