fabric for vocal booth

hello everyone I'm building a small vocal booth of about 4 square meters. all the walls are treated with 15 cm of rock wool (50kg) and covered with a camira cara fabric. When I record the voice I hear some annoying frequencies around 2000-6000 hz which I reduce with the equalizer, even though the room is boringly dead. Could it be the fault of the camira cara fabric that reflects or absorbs frequencies unevenly? In john's projects I don't seem to have ever seen him using fabrics such as camira cara or other similar types of polyester

I'd doubt it - are you sure it's not your microphone? Paul

Hi, welcome. Same as Paul, doubtful. What microphone? Is there anything reflective nearby? e.g. ceiling? Surface for lyrics scripts? Window? Door? Table? are you sitting or standing?
