hello, i am trying to record impulse responses from my studioequipment to correct it's phase and freq responses with e.g. DRC and bruteFIR. I heard the best idea would be to take log sine sweeps for the measuring? it would be great if someone more experienced than me knows of a good method to create sweeps (or chirps) of equal freq.response with linux software?! or maybe some other tips and tricks about audio impulse response measuring with linux? peace mart
