The new audio from the Titan sub disaster has been explained following its recording release on Wednesday (28 February).
The entire globe came to a halt last year after five people died on board a submersible owned by company OceanGate, as it dived down to the wreck of the Titanic.
Contact was lost with the vessel approximately one hour and 45 minutes into the trip on 18 June, prompting a mass scale search effort.

Hamish Harding, Paul-Henri Nargeolet, Shahzada Dawood, Suleman Dawood, and OceanGate CEO Stockton Rush were those on board.
On Wednesday, audio from the Titan sub was released - something that will be heard in full in the new documentary The Titan Sub Disaster: Minute by Minute, which will air on 6 and 7 March on Channel 5 at 9pm.
The doc intends to follow the details of the Titan's dive down to the wreck of the Titanic and what lessons have been learned from the tragic loss of five lives.
During the efforts to locate the Titan sub and re-establish contact, a rhythmic banging noise was heard, which gave some hope that those who were on board the sub might still be alive.

The Canadian Air Force also picked up these noises, something that appeared to be coming every 30 minutes, leading some to wonder if the sub's occupants were still inside and attempting to signal for help.
However, experts stressed that they didn't know what the banging noises were.
It was later concluded that the sub had imploded on the day it had gone missing.
Nonetheless, the piece of audio included as part of the documentary has got a lot of people talking.

In the doc, former Navy Submarine Captain Ryan Ramsey comments: "It could be somebody knocking, the symmetry between those knockings is very unusual.
"It's rhythmic, it's like somebody is making that sound, and the fact that it is repeated is really unusual."
While the audio may provide some answers to the families of the loved ones, experts warned not to expect the bodies of the victims to be fully recovered due to the 'unforgiving environment' of the ocean.

Significant amounts of debris have since been recovered, which have been submitted to investigations into the disaster.
All sorts of stories have appeared since the tragedy, with a number of people voicing their concerns about the Titan sub.
Since the disaster OceanGate's website has said they have 'suspended all exploration and commercial operations'.
