Replying to Audio Editing Help

This is probably a long shot, but if someone could help me out, I'd be forever greatful.

I need this song:

To be cut so it starts at 3:39 and ends at 4:38

From 3:39 to 3:57 I want it to be quieter and sound like its muffled in a tube kinda almost echoey but without any echoes..

at 3:57, right before she says "HEY" the muffled tube sound stops and it goes back to regular sound.

Thats all I need, audio to be cut, and a small effect to be used. If you can do this for me +k, it would seriously help a ton.
