Thanks for your reply Wisslgisse-I find it interesting that our most elemental sounds..water,air,fire,earth,seem to be the hardest ones to catch and i agree with all the points you mention although regarding the oven as sound box i have also recorded(from close outside)the boiler in our oil-fired central heating unit and found a similar wash of low frequencies that didn't make sense,sound realistic.Maybe too near,as you say. As to improving the sound perhaps instead of attenuating some of these lows it might help adding some mids to give definition-like the triggers you mention....I shall keep trying. Thanks again! j.
It's funny you should ask. I was going to leave a comment to that effect when I got around to it.
It's as if the oven acted as a sounding box for the low frequencies and amplified them. There is the sound of the flames, it just seems to be drowned out by the low frequencies.
I don't know how you can improve what you actually recorded. It would have to be a flaw in the recording equipment. And it could just be the interpretation of it by the brain. We often key off certain aspects and thus artificial sounds that trigger those keys can sound more realistic to us than the real thing.
Perhaps we are used to hearing this from farther away and the low frequency sounds are attenuated by then.
