Inside line 8 metro in paris, with open window. Biib, starting, 2 minutes trip beetween two stations, then opening doors. Some discreet voices. Paris, 2020. Recorded with zoom h2, ms positionstero wave, 48khz, 24bits.
Non-functional tube radio warming up, making a loud 60hz hum with lots of harmonics. As a bonus it clicks off at the end. Zenith consoltone. Only because the faq says so: electro voice n/d 257a through impedance transformer into crappy gigabyte motherboard realtek high definition audio. 16bits, processed at 32bits. Audacity sound editor and/or driver wouldn't record mic level so it was very noisy after amplification. Filtered with a (mathematically equivalent) fft constructed whopping 64k length zero phase filter (blackman window) with 5 wavelength width bandpass at each harmonic from 60hz to 5,520hz. For some reason a fraction of some of the harmonics didn't get through so did another pass on the residual noise and mixed that in. Near the beginning there was a sort of brief duplicate signal that descended in pitch so it didn't make it through the filter. I added that bit in. Attenuated frequencies above 3. 6khz because they are pretty much noise, but removing them didn't sound right. Cleaned up the beginning a bit in various ways, cut it down to 15 sec and carefully appended the unfiltered "click" onto the end, which i denoised 12db with audacity's noise reduction.
Water going down the drain. Recorded with zoom h2. Edited with audacity. This sound is cc0 but i highly recommend that you include a link to this page when using it, to avoid misunderstandings.

The microphone was placed inside a stainless steel metal box and placed in my shower. The shower rains onto the box and creates a rich, metallic resonance.
Opening small diploma tube. Please, consider listening my music on bandcamp:. Https://mrthenoronha. Bandcamp. Com/album/mstech-educational-projects-soundtrack.
Recording of a tube journey, starting at one stop and ending at ravenscourt park in london. Includes an announcement at the end and the beeping noise indicating the doors are about to close on the tube at the beginning.
Impulse response of a 60s tube spring reverb unit, fisher k-10 in stereo at 96khz. It is very versatile it looks good on drums, guitars, percussions, synthesizers and vocals, in addition to the beautiful spring sound in stereo.
London underground train approaches waterloo tube station before boarding and doors close. Further recording of the train interior. Recorded using zoom h6n with ms module.
Interior atmo of train leaving the baker street tube station in london, heading to regent's park. Recorded with a zoom h-2, mics set to 90° dispersion.
This is taken from (and an answer to) mxsmanic's "trip on métro line 9 in paris, france", at 2:20 exactly: metro on rails through the tunnel, which resonance creates this sound (very familiar to me as i live here). Interesting to notice that the sound's frequency stays around 483hz, which was (in the ancient solfeggio frequency science attributed to pythagoras) the frequency of "opening consciousness".
Recording of water running down the bathtub drain after the bathorganic rhythms are emerging out of one another as the water is whirling down and getting less in volume as the whirl changes in speed and volume and resonance with the metal tub and the drain tuberecorded with a stereo microphone on minidisc the microphone left dangling and turning over the water to create random panning.
