Experts: Missing jet recordings may have been "edited"

Audio recordings of the final conversations between pilots of the missing Malaysian jet and teams of air traffic controllers on the ground were “edited” before they were made public, voice experts say.

The tapes also appear to be recorded by at least two different audio sources, one of which may have been a digital recorder held up to a speaker, they said. …

“It’s very strange,” said audio-video forensic expert and registered investigator Ed Primeau of Primeau Forensics, who has analyzed hundreds of audio recordings. He said the beginning and end of the recording are high-quality with a low noise floor, meaning ambient background noise is almost silent, unlike the middle.

“At approximately 1:14 (a minute, 14 seconds into the audio, which can be heard here), the tone of the recording change to where to me, it sounds like someone is holding a digital recorder up to a speaker, so it’s a microphone-to-speaker transfer of that information. That’s a pretty big deal because it raises the first red flag about there possibly being some editing,” he said.
