V8 Never underestimate the power of a electric fan...(not necessarily your wife 😆 ) - just a simple thing to move air helps enormously! Might introduce a bit of noise, but you can find a super quiet one I reckon.
Most good mics (and even my crappy mic) will pick up even a quiet fan. So while it will be good in-between takes, I'll have to keep it off during recording ☹️
I have a powerful floor fan in my office that I can direct at me during breaks. So that's something but I'll still be crazy hot while recording.
Part of the problem is that acoustic insulation turns sound energy into heat energy. Foam, blankets, etc. They all do that.
I reckon a good (but expensive) solution is a good aircon that I'd run in-between takes. Get the room nice and chilled and then record for a while (with the aircon off). But it's not my house and I'm not keen on adding an aircon to someone else's house. So maybe one of them portable things?
It seems the GMC branded ones are good. Reliable and not too noisy. (The noise issue being more for my comfort than recording. There's no way you could record (paid) vocals with an aircon on, unless it's just for a YouTube video or something not so important.)
V8 Would be fun to build a little booth out of pvc pipes, not tricky at all - I'd get the lengths precut to my measurements and then it's a meccano set!
Yeah I'm liking this option more and more. It's between the acoustic insulation sponges and this.
I'm considering making some panels just for my office in any case. So that if I do videos, they should sound a lot better. (The reverb in here is nuts! Not something I ever noticed before but live-monitoring a sensitive mic will highlight a LOT of stuff you don't normally notice.)
Here in SA, the fibreglass acoustic insulation seems hard to find but there's always IsoTherm:
I don't think it'll be as rigid as the fibreglass stuff but I might as well pop into a Builders and take a look at the stuff.
I'll (hopefully remember to) keep you posted 😃
