I followed the two methodology for generating impulse response
Method 1: Used the below link reference where I simply convolve the recorded signal by the time reversed sweep signal to get the impulse response. (Estimating the Impulse Response of the Room Using Sweep Signal Microphone Recorded Signal (Input & Output of a Convolution))
The major difference I noticed here is that using method 1, the impulse response is kindof in the middle of the graph and in method 2 , it starts kindof from the beginning of the graph. Is this some kind of wrapping? How would this conversion of wrapping the signal work? The output from method 2 is kindof my desired output- any leads on how it can be obtained?
