please help with unintelligible audio

Might anyone be able to help with the unintelligible audio on this MP3 clip? The section I’m referring to is about 50 secs into the clip and lasts about 1 minute. Can the background noise in this section be lowered or eliminated and the voices made louder? Thank you!

Probably not because the noise is so bad that it is drowning out the noise.

Please also be aware that there is a forum policy that we do not provide support for covert recordings as doings so raises legal issues in many countries. If you require professional help with covert recordings, look on-line for a “audio forensics” professional. Not only will they have access to specialist software, but will also have the necessary legal expertise.
