The cockpit voice recorder from the AirAsia passenger plane that crashed into the Java Sea last month has been recovered.
Divers had already retrieved the other black box, the flight data recorder, from the sea yesterday.
The Airbus A320-200 airliner lost contact with air traffic control in bad weather on 28 December on a flight from Surabaya in Indonesia to Singapore.
All 162 people on board died.
The black boxes contain a wealth of data that will be crucial for investigators piecing together the sequence of events that led to the airliner plunging into the sea.
The cockpit voice recorder is now on board an Indonesian navy vessel and is expected to be sent to the capital, Jakarta, for analysis.
Investigators may need up to a month to get a complete reading of the data.
Dozens of Indonesian navy divers took advantage of calmer weather this week to retrieve the black boxes and now hope to find the fuselage of the Airbus.
Forty-eight bodies have been retrieved from the Java Sea and brought to Surabaya for identification.
Search teams believe more bodies will be found in the plane's fuselage.
