which microphone is better for recording at home , unidirectional or omni directional keeping price factor in mind??
It's impossible to answer this question.
What do you mean by "price factor"? It says nothing at all.
Please....................
Tell us what you want to do with the microphone - what do you want it for? what are you going to do with it?
We really need this information to be able to advise you properly.
And - please - tell us roughly how much you want to pay.
One person's "expensive" is another person's "cheap" - personally I have very few microphones under £1,000 and £500 I consider cheap. To someone else £500 is expensive and wants to spend under £100.
So - please - let us know what you want to pay.
BUT - a good microphone is mature technology - and money spent on a good mic. can last you the rest of your life - it's not like anything with computer technology that you have to replace every couple of years or so.
I still have microphones that I bought in the mid 1980s that I can still buy new today - only today they are five times the price I originally paid for them.
I also still have a mic. that I bought second-hand in the mid 1970s that I can still buy new today.
