I live on the Dutch coast and am used to the sound of a sandy beach: the rhythmic crashing of waves in the surf. At a pebble beach, like the one near Lima, Peru, it sounds quite different. First, you hear the wave breaking, but immediately after, there's a second sound—the water retreating and dragging the pebbles with it.

I made two recordings at that location. The first (https://soundcloud.com/thijs-geritz/pebble-beach-1) was made during calm weather with a gentle swell—you can occasionally hear individual pebbles rolling. The second (this one) recording was made in stronger wind; in that one, you no longer hear separate stones, but a deep, continuous roar.

A binaural recording of a busy street in Chincha Alta. The streets there are mainly filled with so-called mototaxis. You can also hear a coffee vendor promoting her goods by playing a looping pre-recorded message.

Recording of a daily recurring 'honking symphony': cars, motorcycles, buses, and trucks at the intersection of Avenida Javier Prado Este and Avenida Aviación.

The Red Line was a demonstration held on May 18, 2025, in The Hague. The demonstration protested the Dutch government's position on the Gaza war. According to organizers, over 100,000 demonstrators attended. A unique opportunity to capture the actual sound of this sentiment through the various chants heard that day.

This presentation is a collage of several recordings.

De Rode Lijn was een demonstratie die op 18 mei 2025 werd gehouden in Den Haag. De demonstratie was gericht tegen de positie van het Nederlandse kabinet ten aanzien van de Gaza-oorlog. Volgens de organisatie waren er ruim 100.000 demonstranten aanwezig. Een bijzonder moment om het specifieke geluid van dit actuele sentiment vast te leggen met de verschillende leuzen.

Podcast episode #123

This weekend, the Notre-Dame Cathedral in Paris will reopen, five years after the devastating fire of 2019. As a frequent visitor over the years, this magnificent building has always captivated me. One of my passions is creating field recordings, and I've captured numerous audio moments in and around the Notre-Dame.

I've been gathering stories about some of these recordings, including one from my very first session in the cathedral back in 2007. With the Notre-Dame reopening this weekend, it felt like the perfect moment to share this story.

Since I wasn't confident about recording the narration myself with the quality I wanted, I used an artificial voice from ElevenLabs for the spoken text. All the field recordings you'll hear are my own, with just a news clip coming from France24.

I made this recording during a few days of vacation with my wife and daughter. For two days in a row, it was about 34 degrees Celsius, and cooling off in this spring was a good idea.

The Wouter Spring is a natural swimming pool in Belgian Limburg. It's an ideal biotope for several rare species of frogs and salamanders. These amphibians are completely harmless to humans, which unfortunately is not always the case the other way around. Every day, about a million liters of drinkable spring water bubble up from the natural springs at the bottom of the pool.

This recording was obviously not planned. I had to drive at walking pace due to terrible rainfall, which allowed me to simply grab my recorder and place it on the dashboard.

It became a recording of a very specific situation. You can hear the rain and the occasional thunderclap. In addition, you can hear the rhythm of the windshield wipers that had to work hard. The sudden silences in the recording are moments when I drove under an overpass.
