ERROR Serious error is detected! index 0 is out of bounds for axis 0 with size 0:

I got this error running the OF on the Philips TV recording from the Berlin plugfest on a PC with more memory than my laptop.
It didn't happen on my laptop. If cannot be reproduced on another PC then we can close the issue unless/until someone else finds it.

@jpiesing I’ve been unable to replicate the issue on my end. The results should not be empty, as we have a check in place to ensure the audio recording data is not empty before processing. One potential cause might be related to the version of the NumPy package in use. Could you confirm which version of NumPy is currently installed on your PC? This will help us rule out any compatibility issues.
