I need advice about a small mic for the Olympus. I already have the LS-P4 recorder but, at the moment, I want to record all the sounds as I do my daily walk in the wood and on the downs. I live in Surrey, near Banstead.
I used an Olympus ME15 tie-pin mic (it's mono), fixed to the outside of my hat, inside a windshield. Wind noise is not a problem.
I switched in the low pass filter on the LS-P4, turned the recording mode to manual, turned recording sensitivity up to maximum, level 30, and did my walk at dawn.
The recording is OK-ish, but I am not entirely satisfied. In these days of lockdown because of the coronavirus, there are no planes flying. Great! However, to my ears, the recording has a harsh, overly shrill quality about it, which is quite different from what I heard in the woods. Also, I'm not sure if the background noise is the mic or the recorder. The mic is cheap, about GBP22. There seems to be an unpleasant, constant, low-level, suppressed roar (or whoosh - difficult to think of the right word) that does vary slightly depending on how loud the birdsong recording is.
Did I have the recording level too high? Is there some sort of limiter that is producing the sound? Is the mic just no good for this? I don't want a large microphone at the moment, but I am prepared to spend more on a better one.
Any suggestions as to the cause, as to a suitable microphone or otherwise, would be most welcome.
