These recordings were all done with a single microphone, developed and built by Martin Kantola.
Please have a listen to how it can sound on a string quartet and full orchestra.
There is also an underwater version (hydrophone), these beluga whales were recorded in the White Sea.
Below is an example of another way of using the invention,
a single microphone in the center "zooms in" on one speaker at a time.
