Alex Carey's controversial reprieve on the first day of the third Ashes Test was down to an error by the operator of the Snicko technology.
Carey admitted he edged a delivery from England pace bowler Josh Tongue that was caught by Jamie Smith when the Australia wicketkeeper had 72.
Carey went on to make 106 in Australia's 326-8 at the Adelaide Oval.
BBG Sports, the company that owns Snicko, has accepted culpability for the mistake.
"Given that Alex Carey admitted he had hit the ball in question, the only conclusion that can be drawn from this, is that the Snicko operator at the time must have selected the incorrect stump mic for audio processing," BBG told BBC Sport.
"In light of this, BBG Sports takes full responsibility for the error."
BBC Sport understands the sound used for the review was taken from the stump microphone at the bowlers' end, rather than the strikers' end.
This caused a discrepancy between the pictures and sound wave shown to TV umpire Chris Gaffaney.
BBG Sports have confirmed it will investigate the error and take steps to ensure it will not be repeated.
The decision review system technology, which is mandatory in matches played in the World Test Championship, is provided by the host TV broadcaster of the home team.
In this instance, the host broadcaster is Fox, which uses BBG to provide Snicko. Fox has opted not to comment.
