The police surveillance bug was hidden in a stolen car that Jermaine Baker and two other men - Nathan Mason and Gokay Sogucakli - were sitting in as they waited close to Wood Green Crown Court for a prison van to arrive.
Inside the van was Izett Eren, who'd been convicted of a firearms offence, but was using hidden mobile phone to organise his escape.
He's admitted arranging for the men in the car to free him by holding up the van using an imitation Uzi machine gun.
The jury at Woolwich Crown court heard Nathan Mason taking a phone call at 09:00 which appeared to tell him where in the prison van they should expect to find Izett Eren.
Mr Mason told the others: "See as you go in yeah, it's the first door on your right."
Jermaine Baker is recorded as saying: "So the door's here, boom boom."
Gokay Sogucakli queries what they mean, to which Mr Mason replies: "In the van, the first door on the right, that's where he is."
Two minutes later Mr Mason is heard taking a further brief phone call.
At 09:03 the audio picked up shouts of 'armed police'. The jury was not played any audio beyond this point, however a single shot was fired by an armed officer, hitting Jermaine Baker, who died shortly afterwards.
The shooting has been bitterly criticised by some in Tottenham, north London where Jermaine Baker lived.
A police firearms officer has been arrested and the Independent Police Complaints Commission is investigating.
The claim that Jermaine Baker was asleep was made at a community meeting during which community leaders met senior police officers and members of the Independent Police Complaints Commission.
The two men with Jermaine Baker in the car Nathan Mason and Gokay Sogucakli have both admitted taking part in the escape plot along with Izzet Eren.
However, the Woolwich jury is considering whether Ozcan Eren and Eren Hasyer were involved. They have been accused of controlling the escape attempt from a different car.

A court's been played a sound recording suggesting a man shot dead by police in December was awake - despite claims at the time that he'd been sleeping.
Jermaine Baker, 28, and two other men were waiting in a car to try to free a prisoner who was being taken to Wood Green Crown Court in north London.
The recording, from a police bug which had been placed in the car, picked up the men talking to each other three minutes before armed police moved in.
At a public meeting following the shooting in December it was claimed Jermaine Baker had been asleep when he was shot. The recording was played to a jury during the trial of Ozcan Eren, 31, and Eren Hasyer, 25 at Woolwich Crown Court.
They deny being involved in the escape plot.
Chelsea captain John Terry has been offered a new one-year contract by the Blues and is considering whether to accept it, according to the club.

The "totemic" protector of the city, London Stone, is being moved to the Museum of London.
The slab of limestone is reputed to have been brought to London by Brutus, and was possibly originally part of a Roman building.
The saying "So long as the stone of Brutus is safe, so long shall London flourish" has led to the notion that the survival of the city is tied to the safety and protection of the stone.
According to Walk London, for hundreds of years the stone became a traditional site to pass laws, reclaim debts, swear oaths and make official proclamations
The stone will be on show in the museum's War, Plague and Fire gallery.

Ellie was transferred to another hospital and Mr Butler said he went to a chapel and "prayed and prayed on my knees".
"This guy come in to us - a proper doctor. He came out and said don't worry, she is going to be fine."
Mr Butler was later convicted of harming Ellie but this was then quashed on appeal.
The father accused of murdering his six-year-old daughter Ellie Butler in a fit of rage has told how he was left "devastated" when she was taken into care as a baby.
At the Old Bailey, the 36-year-old described how Ellie looked "sheet white" when his partner Jennie Gray, also 36, brought their daughter to his house in February 2007.
Mr Butler took her to a hospital where a doctor told him that Ellie would not make it through the night.
"I couldn't believe it. Clearly nothing like that has gone on. We couldn't get it in our minds."
Mr Butler, from Sutton in south-west London, denies murder and child cruelty.

London Assembly Conservative member Gareth Bacon said voters needed to have confidence in the voting process after criticising the delay in the final result at City Hall and voting problems in Barnet.
Labour's Andrew Dismore described what happened in Barnet "as a disaster waiting to happen" which was down to inexperienced staffing, lack of supervision, and cuts to the elections team.
He added that the council needed to be put into special measures for the EU referendum and that its council leader should stand down.
