### Finding start point of a curve

I'm currently working on a project where I have to measure the latency of a given system. Below you can see a exemplary image which shows the input pulse (green) and the response (blue). In order to ...

### A Python code for blind estimation of RT60 from recorded audio

I have an audio recorded, recorded by a 2 mics array. I want to a Python code that get the audio as input and estimate the RT60 reverberation time. I do have a function that estimates RT60 from a ...

### How can I obtain the impulse response using a dual channel FFT?

I want to obtain the impulse response of a space to calculate reverberation time using the Schroeder method. This space is characterized by the short reverberation time within 0.5 seconds due to the ...

### How to find impulse response of the input signal in Python?

I had to read input .wav audio file first, then add Gaussian white noise to the input audio signal and I've finished that part. Now I have to add a channel model whose impulse response is: ...

### Impulse response amplitude : Sine sweep method

I'm trying to implement Farina's method in python to measure impulse response with an exponential sine sweep. I convolved the output of the system with the inverse filter of the exponential sweep. ...

### Identification of properties of a given FIR filter

I have a FIR filter which is described via following transfer function $$H(z) = h(0) + h(1)\cdot z^{-1} + h(1)\cdot z^{-2} + \ldots + h(23)\cdot z^{-23},$$ where the coefficients have below given ...

### Find transfer function of physical system

I want to detect an impact at a table using accelerometers. I thought a useful thing to do was to find the transfer function of the table I am using, so that I have an idea of how signals in the table ...

### "Instantaneous impulse response" in a linear time-varying system

I have a LTV (linear and time-varying) system. So, $h(\tau, t)$ is the "instantaneous impulse response" at time $t$ such that if the input signal is $x(t) = \delta(t - t_0)$ (an impulse at ...

### how to differentiate between random and impulse signals using MATLAB or python?

I have data collected from an experiment of shaking a 4-storey steel frame using a shaker and responses were recorded using accelerometer sensors. I realised that in the dataset some of the signals ...
