155 Royalty-Free Audio Tracks for "Signal Processing"

This is a sound recorded with a handcrafted electromagnetic microphone (that is why is in mono format). The machine recorded is used for signal processing tasks at cbc (upf) for their experiments on brain cognition. As researchers of the center for brain and cognition, we work to advance our understanding of how experience influences the emergence of structure and function through computational and experimental investigation. We are also interested in understanding how mechanisms regulating brain development interact with the effects of experience to produce the structural and functional characteristics of the brain. These lines of research clarify how specific biological mechanisms routinely support the emergence of cognitive functions, leading to insights into why experience is so important for normal brain development.

The guest room i am staying in has a tile bathroom. Each time i take a shower, i hear this magnificent hum of the water heater clicking on and then turning off once the shower water is stopped. I was fortunate enough to hear it click on while i wasn't in the shower and captured about 30 seconds of it before it died. Infinite variation, impossible to replicate. At the end, as the water heater shuts down, it clicks down into the lowest ranges of the frequency spectrum; i didn't hear it until i listened to the recording but the couple of seconds of that are just as magical. Wish i would have left the recorder running!. Captured with a zoom h3-vr to ambix format at 96k24bit and bounced to stereo. Processing: 24db gain to all 4 clips, izotope spectral denoise to get rid of the air in the room and izotope ozone to enhance the bass signal a touch. Enjoy!.

Each segments has an ambience sound transformed with a musical instrument or two.

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.
