Verde River Recordings

These are works in progress, representing efforts to test equipment, recording techniques, locations, and mixing approaches for field recordings along the river. They also represent my love for being at the river and for listening to its many wonders. The recordings are arranged from the headwaters near Paulden and on downstream for 190+ miles. Human sounds (including sounds from a sometimes noisy recordist) are not removed. My approach is to record the riparian soundscape “in use,” recording the situated, fleeting geophony (non-biological), biophony (flora and fauna), and anthrophony (human-made) of each setting on the given hour, day, and season.

Soundwalk from Bartlett Dam four miles downstream. March 2023.

Equipment: Sony PCM-D100, ORTF (120 degrees), Rycote wind protection, 48 kHz/24-bit.

Processing: EQ, Compression

These recordings were made shortly after the heavy floods and flow in the Verde-Salt corridors began and water was released from Bartlett Dam. The soundwalk begins in the floodplain below the dam (Song Sparrow, Northern Cardinal), stops at a couple of points downstream (Song Sparrow, Anna’s Hummingbird, Black Phoebe), before climbing up and away on a trail from the river to a ridge (Cactus Wren). It then turns back up stream, stopping at the gauge station (Northern Cardinal, Lesser Goldfinch, Anna and Costa’s Hummingbirds, Black Phoebe) along the way.
