In lossless mode the amount of compression obtained \ depends on the nature of the waveform. Those composing of low \ frequencies and low amplitudes give the best compression, which may \ be 2:1 or better. Lossy compression operates by specifying a \ minimum acceptable segmental signal to noise ratio or a maximum bit \ rate. Lossy compression operates by zeroing the lower order bits of \ the waveform, so retaining waveform shape. homepage http://www.etree.org/shnutils/shorten/ platforms darwin master_sites http://etree.org/shnutils/shorten/source/ checksums md5 71332b2b45cf41db2c512190c6aad623 configure.env CPPFLAGS="-O3 -funroll-loops -no-cpp-precomp"
