Not applying a 300Hz high pass filter results in -inf / nans in some files and indices

[m4gpi]

When we switch off a high pass filter, we get nans / -infs in the following indices:

spectral flux 
bioacoustic index 
acoustic complexity index
log(1-temporal entropy)

Steps to reproduce

uv run pipeline --high-pass-filter=0 **your-other-args-here
