Output files will have the same format as the input file where possible and not Input file format options need only be supplied for files that are headerless. V Increment or set verbosity level (default 2) levels:

version Display version number of SoX and exit T, -combine multiply Multiply samples of corresponding channels from all temp DIRECTORY Specify the directory to use for temporary files

single-threaded Disable parallel effects channels processing S, -show-progress Display progress while processing audio data R Use default random numbers (same on each run of SoX) replay-gain track|album|off Default: off (sox, rec), track (play) q, -no-show-progress Run in quiet mode opposite of -S plot gnuplot|octave Generate script to plot response of filter effect play-rate-arg ARG Default `rate' argument for auto-resample with `play' multi-threaded Enable parallel effects channels processing M, -combine merge Merge multiple input files (instead of concatenating) combine mix-power Mix to equal power (instead of concatenating) m, -combine mix Mix multiple input files (instead of concatenating) no-clobber Prompt to overwrite output file input-buffer BYTES Override the input buffer size (default: as -buffer) help-format NAME Show info on format NAME, or NAME=all for all help-effect NAME Show usage of effect NAME, or NAME=all for all h, -help Display version number and usage information G, -guard Use temporary files to guard against clipping effects-file FILENAME File containing effects and options dft-min NUM Minimum size (log2) for DFT processing (default 10) D, -no-dither Don't dither automatically combine sequence Sequence all input files (default for play) combine concatenate Concatenate all input files (default for sox, rec) clobber Don't prompt to overwrite output file (default) buffer BYTES Set the size of all processing buffers (default 8192) GLOBAL OPTIONS (gopts) (can be specified at any point before the first effect): Use the given URL as input file (where supported) ' Pipe input from external program (where supported) n, -null Use the `null' file handler e.g. d, -default-device Use the default audio device (where available) Pipe/redirect input/output (stdin/stdout) may need -t
