% This script assumes that WSJ0's wv1 sphere files have already
% been converted to wav files, using the original folder structure
% under wsj0/, e.g.,
% 11-1.1/wsj0/si_tr_s/01t/01to030v.wv1 is converted to wav and
% stored in YOUR_PATH/wsj0/si_tr_s/01t/01to030v.wav, and
% 11-6.1/wsj0/si_dt_05/050/050a0501.wv1 is converted to wav and
% stored in YOUR_PATH/wsj0/si_dt_05/050/050a0501.wav.
% Relevant data from all disks are assumed merged under YOUR_PATH/wsj0/
