Isar Sound Map. Sieben Rippen near Bruckbergerau. The Sieben Rippen (seven ribs) is a short section of rapids on the River Isar. The bed of the river and the ribs here are made of a conglomerate stone mix (psephite) which is the only place it occurs on the middle and lower stretches of the Isar.
I used a selection of microphones - a stereo, a shotgun and two hydrophones, from various positions to record the differences in the flow.

An especially busy day underwater at one of my favorite hydrophone listening spots; the Marina Drive bridge between Long Beach and Seal Beach. I can hear croakers, for sure, and what may also be garabaldi. I have seen, and heard them over in the marina and the popping sound they make is pretty distinct.

A rookery in Landshut recorded early on a Sunday morning. I went back there the following Sunday with a parabolic microphone to record close ups of the bird calls. I´ve dropped them into my original mix. I think it gives a little more interest to the general recording.
There are at least 1000 rooks, jackdaws and a few crows roosting here in the centre of town. This area with many trees and two small streams incorporates the local hospital, the swimming baths and a town park. There´s not much human sound to hear except for the church bells which, I think give the recording an acoustic fingerprint of birds using the town as a safe refuge to roost. They come from a large area surrounding Landshut.

The first proper outdoor test of my new homemade 'Gladys' hydrophone.  Some common frogs in a neighbours garden pond.  Thanks Katie!  Pleased with how they sound.  Nice flat response.
