aspcore.correlation.is_autocorr_func(func, verbose=False)

An autocorrelation function should be of shape (num_channels, num_channels, max_lag)

Assumes the autocorrelation is real valued, from a real-valued stochastic process

The evenness property is inherent in the representation as

func = [r(0), r(1), …, r(max_lag-1)], as only one side is recorded
