Before Change

    =======
    std_signals: copy of signals, normalized.
    
    signals = np.array(signals).astype(np.float)
    buf = signals.T
    buf -= signals.mean(axis=-1)

After Change

        if not detrend:
            signals -= signals.mean(axis=0)

        std = np.sqrt((signals ** 2).sum(axis=0))
        std[std < np.finfo(np.float).eps] = 1.  // avoid numerical problems
        signals /= std
    return signals
