# Parameters of standard audio channel filters

I want to do some simulations of speech recorded on microphones. In order to simulate the channel response, are there any standard (FIR) filter parameters available that I can use?

• How were the speech files recorded that you want to use for the simulation? I mean that there's also a channel in the original recording which may or may not play a role in your simulation. – Matt L. Jul 10 '14 at 7:44
• @MattL. you are right. I forgot about that factor. I don't have access to reference mic characteristics, will have to assume it to have flat response. – user13107 Jul 10 '14 at 7:50

• Dummy way. Take the frequency characteristic provided by manufacturer in the manual, trust him, sample it, and use as the input for algorithm mentioned above. In MATLAB that would be firpm function.
