I was set up to record a Mark IX Spitfire at the Imperial War Museum, Duxford, near Cambridge when an announcement came over the PA system that a couple of Chinook helicopters would be carrying out a "Tactical Landing"... Well, why am I telling you this? You can hear for yourselves: the PA announcement comes mainly from the left and slightly to the rear with a lot of excellent bounce-back from assorted hangars. Some kids run up to watch the fun and the two Chinooks duly arrive from the left and depart to the right, with more bounce from the rear. Rather nice, I think.

Some recordings made during a performance of a comedy in London's Glittering West-End! The microphone was mounted on the front of the first circle and there is a some sound from the stage to give location. The theatre is a traditional horseshoe shape, so the audience noise should wrap round about 180 degrees and there should be sounds from both above and below.

Recorded on a chilly Friday night in Dublin's Temple Bar area. Dublin is a favourite destination for stag and hen parties from the UK, so the atmosphere can sometimes be a little rowdy. Voices and music from bars all around the mic position.

First recording using a Core-Sound TetraMic and a new, as yet unreleased, audio interface. The Orfeo Trio is Lucy Jeal, violin, Simon Brown, viola and Alexander Somov, 'cello. This was a pre-concert run-through for a small invited audience in a North London church which is shared with a nursery school, hence the occasional small child. The piece is the second movement of Beethoven's Trio in C Minor, Opus 9 No.3. I think it shows off both microphone and interface in a rather good light, as well as the trio.

Please note that this recording is included purely for the sake of interest; i.e. this is what happens when you position a microphone about fifty feet away from the front of a WWI field gun firing blank charges. It's not meant to be a great recording, but it does show how well the microphone can cope with that sort of abuse. This is a recording of the six guns firing in order. You can hear how the initial pressure wave diminishes as the distance and angle increases. High level playback will probably harm your speakers - don't blame me!
