stereo noise from detergent foam sparkling.flac

I was surprised by noise coming from the bathtub when I saw there was a pair of sneakers soaking in foam in a basin which wasn’t going away. Because, I presumed, it was generated anew by detergent in the water. The sound was so uniform and crispy, I ended up recording it (standing as close as I could).

Then I took one half of the recording and used is as mid channel, attenuating high frequencies a bit, and another half went as a side channel with low frequencies attenuated. So if you change stereo width, it would slightly change the tone.

Recorded with Redmi Note 5. Normalized, denoised and cut in Audacity.
