|Recently, we had two nature sound friends visit us from the US; Dan Dugan and Sharon Perry of the Nature Sounds Society. A lovely opportunity for chatting, good food, wine, a stroll in the bush, and of course recording and comparing of microphone rigs.
It was their first time in Australia, hearing magpies, fairy wrens and kookaburras. Dan had with him a Zoom H2 (Oomagamma-modified – the internal mics removed and replaced by 3.5mm stereo jacks for front and rear pairs) and a quartet of Telinga clip-on microphones. I had my two preferred stereo rigs; a SASS and PIBO.
After a late night, Dan and I nevertheless managed an early rise for the dawn chorus in our bushland. We set up our rigs one in front of the other, with Dan’s mics using a tree as a stereo baffle – a ‘tree ears’ deployment. He also ran a rear pair some 10 metres out on either side to record surround, but for this comparison you’ll only hear the front pair.
This makes a good audio comparison between a light-weight and relatively inexpensive rig (Telinga/Zoom) against two more robust and upmarket ones.
Each sample represents exactly the same time sequence, as recorded by the three mic systems. I’ve balanced the recordings to a similar volume level, and as we were each running different low frequency profiles (bass rolloff), also equalised bass frequencies (below 100Hz) for subjective listening.
