Bicycle spokes - front wheel (Dare2025-2)

Description

I spun the front wheel of my bike and then held a pen against the spokes. This is what I recorded. Recorded with Iphone 13 using the app "Röstmemo" (voice memo). The app creates M4A-format (MPEG-4 audio). I convert to wav. Stereo recording. Recording normalized -3dB.
