Summer Storm (memory)

My track for ambient online one sample dare 30. the original sample here: https://soundcloud.com/lighthugger/pipes-ao-osd-30 i wanted this to sound like a summer storm brooding, a muggy humid feel, and it being a long ago memory. In audacity i took the whole sample paulstretched it to ~8 minutes and really smoothed out (cos there's loads of elements in the sample that i wanted to create gradual shifts and depth) then increased the volume of the low end rumble. then time stretched it down by half so the tonal shifts are more pronounced (and cos i'm running out of time on my sc account!) then i recorded it to cassette on my teac tape deck and then recorded this back onto pc with a sony ex505 walkman to give a bit of hiss and warmth (and for that long ago memory feel).
