# Note that -pthread is only included so that older Linux builds will be thread
# safe.  We call malloc, and older Linux versions only linked in the thread-safe
# malloc if -pthread is specified.

# Uncomment this if you want to link in spectrogram generation.  It is not
# needed to adjust speech speed or pitch.  It is included primarily to provide
# high-quality spectrograms with low CPU overhead, for applications such a
# speech recognition.
