Make a song sound like it’s playing in another room
The party next door, music from upstairs, a TV through the wall: each one sounds a little different. Hidden Party Echoes has a room for each, and you can hear them on your own song straight away.

Neighbor’s party is the classic one: music through a shared apartment wall. Upstairs keeps even less treble, so it’s mostly bass and thumps. TV through wall works best on speech and dialogue.
Distant concert sounds like an outdoor show a few blocks away. Car outside is a parked car with the stereo up. Bathroom and Phone speaker are for when you want the song in a small tiled room or coming out of a phone.
