Alright, I need to know what program you use to make these. Seriously.

Well it definitely does sounds like flanger/phaser use. Though, I hear a very slight difference in color, which almost convinces me that it isn't. I like the mischievous melody of it. It sounds like drowning strings, and I especially like the second half beginning at 00:46 where the lower pitches are introduced, they sound like a drowning bassoon. I really can hear an entire orchestra here. I like the reverb on this as well. It makes it sound like I'm standing in a mall, it's relaxing. I'm basically just confused on how this was made. This can't be just manipulated water dripping...well either way, I really liked the creativity of this and sort of wished that even if this is entirely water, some other instruments and parts could have been added in as well. But I guess that would defeat the initial purpose of this being entirely underwater. Anyways, great work!
