  The hadron energy resolution of a highly granular CALICE analogue
scintillator-steel hadronic calorimeter was studied using pion test beam data.
The stochastic term contribution to the energy resolution was estimated to be
58%/sqrt(E/GeV). To improve an energy resolution, local and global software
compensation techniques were developed which exploit an unprecedented
granularity of the calorimeter and are based on event-by-event analysis of the
energy density spectra. The application of either local or global software
compensation technique results in reducing of stochastic term contribution down
to 45%/sqrt(E/GeV). The achieved improvement of single particle energy
resolution for pions is about 20% in the energy range from 10 to 80 GeV.
