Earlier this week we left the Lento box out to record overnight. Persistent rain was forecast from midnight onwards after a spell of dry weather. We never lose interest in the sound of falling rain. Being outside during a shower invokes strong feelings that must have evolved over millions of years. 

To make these local rain recordings we normally set the Lento box on a tripod underneath a tarpaulin that's stretched out over the back yard. The tarpaulin acts like a horizontal cinema screen, catching the drops on an X Y axis and producing the type of rainscape sound that we've shared in many other episodes. This time though we wanted to hear what the rain sounded like when the Lento box was exposed, sheltered only under plants. 

We set the Lento box beyond the yard, close to an old Victorian brick wall. The space immediately around the box was dense with leafy foliage from a wisteria plant growing along the top of the wall. It provided good shelter, or so we thought. 

The recording worked. The Lento box, while completely soaked, did reliably capture the wide and shifting soundscapes throughout the night, perfectly. Falling rain, as it came down over many little back gardens in waves of varying intensities and droplet sizes, determined by atmospheric conditions high above. But being so exposed to the elements, and sensitive to all kinds of sound, large heavy rain drops hit the box that fell between the wisteria's abundant leaves. Each drop landed on the box with a sharp tap. Hundreds of taps, maybe more than a thousand. Each drawing the ear's attention to the microphone box itself, which as with a camera should never be in shot. 

Our choice was to scrap the recording, make a better overhead rain absorption solution and try again another night. Or listen through every second with a keen ear and a micro editing tool to unpick each drop that struck the box. 

Of course we did the latter and it took six hours. Crazy perhaps, but as we cleaned off ten seconds, and then half a minute, and then two minutes, then five, the process developed a momentum of its own. Like restoring a damaged painting bit by bit, gradually restoring to clarity the spacious and detailed sound image of the night. The countless raindrops as they fell onto the wisteria and the leafy shrubs. A meditation on one unique night, of falling rain.
