Recently I came home late at night and as I was walking up to the front door I heard this great sound of trickling water. Toronto has had an unusual amount of snow this winter and on this particular day the temperature had shot up and the snow had been melting all day. The problem is that until the snow covering the sewer grates melts there is no where for all the rest of the melt water to go, but once the grates melt through the water falls into the sewers like a mini waterfall - and that was the sound I heard that perked my attention. I quickly (and silently as my lady was already fast asleep inside) grabbed my field rig and started recording the water.
The great thing about 2am is that traffic is minimal so I was able to get a pretty clean recording. What surprised me most was the lack of natural reverb down in the darkness of the sewer, I was expecting a whole lot of slap back but there was basically none. So I loaded the recording up in my DAW and threw on some verb to get that water dripping in a cave vibe going.
That is more what I was expecting to begin with. Since I had the reverb plugin on the track already I thought I would play around with crazy impulse responses to see what I could get out of the sound. Recently I worked on a episode of an animated series where the "camera" went into the walls of the house and through the plumbing pipes and I had a real hard time getting a good wet pipe interior sound as the camera tracked through the various pipes - this could have come in real handy had I had it at the time. Some nice gurgles metal ring going on here:
Finally I came across this with a bizarre impulse I stumbled across. It kind of turns the babbling water into an alien jungle AMB. It still needs some tweaking but it could be the start of something for all the Avatar copycat movies that are sure to come out in the coming years.
