Really need to isolatesact,

So I have some audio… a bunch of audio, that was recorded in kind of a loud bar, however the voices I need to isolate are definitely the loudest. In fact, looking at the audio, i think it is the entire bright blue section in the middle and the rest is all noise. Is there a way to remove this? REALLY important! Thanks!

No. If the noise is so loud that it masks the audio that you wish to hear then you need to re-record without the noise.
If this task is in relation to legal proceedings, then you should seek professional advice from an “audio forensics” expert.
