You need to cross-correlate those two wavfiles : from wikipedia "cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other"
The result obtained will give you a measure of the similarity between those two audio signals depending on the time.
Therefore you will need to find the time for which ...

Answer:
Whenever the impact happens, that portion of audio has to be detected( if you want to automate it) or else you can identify those sections manually.
To automate it you need to identify characteristics of the audio during the impact, for ex: the frequency contents, or time spread. A good approach to combine these two characteristics is to either do a ...

I've simulated your system, and since it's a four-stage phaser you do get two notches and one peak in between, if you don't count the more or less pronounced peaks at DC and at Nyquist.
The frequency response of your system is
$$G(e^{j\omega})=\frac{1+(1-f)H^2(e^{j\omega})}{1-fH^2(e^{j\omega})}\tag{1}$$
where $f$ is the feedback value, and $H(e^{j\omega})$...

If I follow the OP’s description properly, the description is what would be a comb filter, given the all-pass filters operate as delay lines (over a certain frequency range of operation). The sum of a signal with a delayed copy of the signal would be a "comb" response, that would cyclically go between constructively summing and cancelling since the phase ...

The usual answer is that that you must convert by integer ratios, therefore 44.1 kHz to 48 kHz requires integer up and down conversions. Since this has been repeated in DSP text books for at least the past 50 years, it's almost always the answer you'll get using a ratio of m/n, where m and n are integers. The typical way uses a windowed sinc function—sinc ...

The consumption time and transmission time is identical: One second of data is still one second of data regardless of sampling time.
The greatest common divisor between the two rates is 300, thus to resample this exactly from 44.1KHz to 48KHz you would need to use the ratio $160/147$ (and the inverse for the other direction):
$147$ is factored into $3, 7^...
