I uncap and cap a tube of lip balm. 80 hz high pass filter applied and some minor editing of the noise floor. Recorded with a cad e100s into a focusrite scarlett 2i2.
This sound was recorded at the campus of poblenou of the pompeu fabra university in the corridor linking the cafeteria with the tanger building. Noise makes to open and close the glass door that connects the hall of the café with the passage that leads to the tanger building. This recording has greater duration than the glass door noise 1.
