package require port 1.0 name shorten version 3.5.0 revision 0 categories audio archivers maintainers jpm@opendarwin.org description Fast compression for waveform files long_description Shorten reduces the size of waveform files (such \ as audio) using Huffman coding of prediction residuals and optional \ additional quantisation. 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 cde81555c8dae3b011c4a15d320c7312 configure.env CPPFLAGS="-O3 -funroll-loops -no-cpp-precomp" contents \ bin/shorten \ man/man1/shorten.1
