Quote John Willett:Quote Hugh Robjohns:
If you think about the way a (cardioid) mic works, it becomes very obvious that a broadband absorber (eg. duvet) placed in front of the mic but behind the performer (and ideally, extending around the sides too) will have a significantly greater effect in reducing unwanted room reflections than a 'filter' placed behind the mic.
Both are useful, but I'd rig the duvet before worrying about a filter.
I agree with Hugh on this.
I use an absorber behind the singer, in front of the mic.. This minimises room reflections bouncing back off a hard surface into the mic.. It works very well.
Personally, I can't really see the point of these reflection filters as they are behind the mic. where the mic. is least sensitive anyway.
Is the idea that it prevents the sound from going beyond the mic and then reflecting off the wall facing the singer, to then rattle around in the room?
