Modular Sounds Thru Cheap Computer Speakers Recorded At A Distance With Phone.wav

This recording is inspired by AlienXXX http://freesound.org/people/AlienXXX/sounds/345510/
Made a little patch on my modular, still missing its (main) oscillators. I let the patch sound thru a pair of cheap computer speakers that I use as monitors. In an adjacent room, close to an open window, I put my phone and record. This is the unedited outcome. The recording was made 09:00 (16-05-11). Unfortunately nothing happened outside the window. Even the birds was quiet. I think there is a hint of feedback in the sound? First I planned to record with an old tape recorder, but I couldn’t find it...
I think this recording should be listened to with low volume. May by it was a mistake to amplify the sound in audacity? But I think there is a nice room ambiance to the recording.
Ideas for next time. Use guitar amp. Find old tape recorder. Don’t put recording device to close to window.
