I was slowly releasing air from a water bottle through a hole in the cap, then threw it into audacity and applied paulstretch and some other effects. Sounds like eerie hl2 citadel strange talk ambience.
Recording of a vintage room fan (bond air recirculator). Bass is boosted and the sound is reversed. Very relaxing, noise masking, sleep-inducing sound especially good for those people with tinnitus.
A sound made to represent air rushing around your head when riding a bicycle downhill. Recorded by simply blowing on the mike and then using some eq. Feel free to download and use, just leave a comment, please.
Finally rain after a hot dry july 2018. 10 mins rain with 3 large thunder claps. Not recorded as loud as i should have, it was dark. I used an h4n through an open window.
Recording of a shaker table using three contact microphones, blended in post to give a good mix of the sounds the table was making. Variations in the tone are the result of issues with the shaker table's power supply.
A single plane coming in from the right to the left, creating some nice reverbing sounds at the end of the recording. Some low level sounds from bystanders. This is a recording with normal input gain.
A stereo wav recording from a zoom h1n during a thunderstorm today. One siren picks up followed by several more producing a convincing stereo image. I have done a basic bass roll-off, but have left it otherwise untouched. If you have a spectral editor you can probably clean out more of the noise, but i couldn't do so and keep the sirens sounding good.
A balloon popping by stabbing a scissor blade into it. Not very impressive. This sound is cc0 but i highly recommend that you include a link to this page when using it, to avoid misunderstandings.

Buzzing drone noise made by a toddler's toy which was malfunctioning due to low batteries. I modulated the sound by moving the mic around the toy and covering / uncovering it with a bowl during recording.
