All conversions are handled by CoreConverter.exe, this program can be found in C:\Program Files\Illustrate\dBpoweramp\

 Required:

-infile="filename"        // specifies input file to convert from, can be '-' for standard input
-outfile="filename"      // specifies output file
-convert_to="Wave"    // Codec converting to

Optional:

-priority="low" "high" "idle"   // sets converter priority, default is normal
-silent                                // only outputs errors to StdErr
-errorfile="filename"             // errors written to filename (otherwise StdErr)

-noidtag                             // do not try to write any id tags
-tag="element=value"          // specify an ID tag, example -tag="artist=Madonna" use {qt} to put a quote " in the final string
-tag="element1=value1"
-processor="n"                   // allies to a processor (on multi-cpu system), where n is 1=CPU1 2=CPU2, etc
-dspeffect1="name=cmdline"  // a DSP effect (see example below, important as " in the DSP effect command line are replaced with {qt} )

std input:

When using '-' for input filename the audio must be supplied 'raw' (no headers) to the stdin pipe, specify the parameters as follows:

-sourcefreq="44100"           // stdin frequency
-sourcechannels="2"          // stdin channels
-sourcebits="16"                // stdin bit depth
-sourcelength="1000"         // stdin source file length in mili-seconds

Pipes used when CLI encoding:

[StdIn] used only when input filename is "-"
[StdOut] shows info to the user (also info from codecs), output is ANSI
[StdError] all error messages, output is ANSI

...followed by Codec Compression CLI, this is specific to each encoder, see the help file for the encoder for CLI details (Start >> Programs >> dBpoweramp Music Converter >> Help >> Codecs)
