An optional highpass filtering has been implemented.

Overlap length (in samples) returned in output variable setup is now correct. Previous versions incorrectly returned overlap percentage.

An error occurring during estimation of autospectrum has been fixed.

- Improved documentation.
- New types of averaging: median filter and variance of spectral unit.
- Results of the STFT of multiple signals are now returned as 3D array.
- Performance improved significantly.
- Accuracy of PSD slightly improved.

- User can define frequency resolution of the analyser.
- The window function can be directly specified as a vector.
- The analyser setup can be returned as an output variable.
- Warning messages are now displayed.
