Filter response curve

  • Thread-topic: Filter response curve

May I ask what ways are there to get the response curve of a filter?  My current method is to pass a white noise source through the filter and write the output to disk, then read the disk output into Audacity and plot the output.

This is the only way that I’ve come up which makes sense as I believe Audacity is using some form of Fourier Transform on the data.  I’ve been looking at the vDSP functions for FFT.  This is the direction that I am headed, using FFT but even though I don’t know any other way, I feel this must be using a sledgehammer to kill a mosquito. 

 

Any thoughts on this?

 

Thank you,

 

 

W.
