formicoli_undertow_04.wav

Recording of sea undertow on the beach of Formicoli, Vibo Valentia, Calabria, Italy, the 19th Agust 2022 16:44.
The sound was recorder with a Zoom H1n with windshield at a short distance from the crashing of the waves on the beach.
The waves are driven by a light, gentle wind.

The sound was recorded by holding the microphone in my hand while I dived knee-deep into the water and walk, filming the crashing of the waves (also on my legs).

High-frequency sound details (the foam of the sea, the impact of waves on each other, etc.) are much more audible here.

Processing:
* volume adjustment;
* 120Hz High pass filter (to reduce low some low frequencies rumble due to the wind);
* cut and crossfade to eliminate very few mechanical noise of my hand on the mic;
