This directory contains simple UNIX command-line tools for soundfiles. To learn the usage of each command, run it with no arguments. asciitosnd converts 16-bit ascii to a soundfile atcenv computes the amplitude envelope of an ATC-compressed sound dsptosnd converts a DSP commands file to a soundfile sndblockdc removes the (possibly drifting) DC component of a soundfile snddiff subtracts one sound from another, producing a difference sound sndedh edits the contents and/or size of a soundfile header sndinfo prints the contents size of a soundfile header sndrealloc test sndRealloc() function (for changing sound size in memory) sndrms compute root-mean-square and other stats for a sound file sndrmsenv sndrms on successive blocks (short-time rms and other stats) sndscale scales a sound by a gain factor sndsub subtracts one soundfile from another sndsum adds one soundfile to another sndsynth simple prototype sound synthesis program sndtoascii converts a soundfile to 16-bit ascii sndtoasm converts a soundfile to ASCII suitable for DSP assembly sndtodec prints soundfile in decimal sndtohex prints soundfile in hex sndtomono converts stereo to mono by extracting or averaging channels sndtostereo converts mono to stereo sndtrim trims away zeros at the beginning and end of a sound
