before that, hi there I’m new in using audacity 
great program though I am knowledgeable in this kind of software 
if anyone has a realtek HD audio manager(I am sure most has it) and if you set the sound effects environment to concert hall, it sounds amazing! though I can’t figure out the setting’s to get that sound
kindly help me please , thank you in advance!
Open the Realtek HD Audio Manager and select the effect that you want from the “Sound Effects” tab.
thanks for the reply! yes I know how to do that, but How do I record it if possible in my computer? since I don’t have the hardware to record 
or should I say, how to do I produce a new file that sounded just like the concert hall in the Realtec hd audio manager?
The affect you are after is reverberation and/or echo. See here: http://manual.audacityteam.org/manual/help/manual/man/index_of_effects_generators_and_analyzers.html#Add_reverberation_or_echo
thank you very much ! helped alot ! now I need to find the best equalization to make the sound more whole and solid thanks a bunch mr.steve!
