}
The scripts can be used to estimate the (acoustic) impulse response of a device-under-test (DUT) in the presence of clock drift between the measurement setup and the DUT.
For more information on the algorithm, see https://www.microsoft.com/en-us/research/publication/clock-drift-estimation-compensation-asynchronous-impulse-response-measurements/
Copy the scripts in this project to a folder and run RUNME.m from within that folder to run through the following steps:
- Generate a test signal for impulse response measurements
- Simulate a noisy, reverberant, asynchronous recording of the test signal
- Estimate the clock drift and impulse response
