scritcher command reference

scritcher scripts are shell-like commands separated by a semicolon.

parameters of the arg type

some commands allow a :N syntax where N is an integer to use a given argument when scritcher is called. so, for example, calling a script:

load :0;
showpath;

and then doing scritcher path/to/script.scri arg will print arg on the screen and then exit.

split and index arguments

plugin commands have a split and an index argument so that you can select where in the file you want the plugin to be ran.

so, if you did plugin 3 1..., it would split the file in 3, then get the part that is of index 1 (starting at 0).

Keep in mind parts start from the bottom of the file.

load path_or_arg

Load a file into memory. The file MUST end with the bmp extension (and so MUST be a bmp. feel free to put other files, no warranties are given.)

amp split index gain

Run the eg-amp plugin over the given slice of the file.

rflanger split index delay_depth_avg law_freq

Run the Retro Flanger script from the SWH plugins.

Parameters:

  • delay_depth_avg: Average stall (ms), 0..10, default 2.5
  • law_freq: Flange frequency (Hz), 0.5..8, default 1

eq split index lo mid hi

Run the DJ EQ plugin from the SWH plugins.

lo, mid, and hi are the respective dB gains for each frequency range.

All three ranges accept gains from -70dB to +6dB. Default is 0 for all (no action taken).

Multiband EQ from the SWH plugins.

In respective order, the band arugments represent the: 50Hz, 100Hz, 156Hz, 220Hz, 311Hz, 440Hz, 622Hz, 880Hz 1250Hz, 1750Hz, 2500Hz, 3500Hz, 5000Hz, 10000Hz and 20000Hz frequencies.

All of them represent the band's gain in dB. The range is -70 to +30dB, default is 0.

chorus split index voices delay_base voice_spread detune law_freq attendb

Multivoice Chrorus from the SWH plugins.

Parameters:

  • voices: Number of voices (int), 1..8, default 1

  • voice_spread: Voice separation (ms), 0-2, default 0.5
  • detune: Detune (%), 0..5, default 1
  • law_freq: LFO frequency (Hz), 2..30, default 9
  • attendb: Output attenuation (dB), -20..0, default 0

pitchscaler split index mult

Runs the Higher Quality Pitch Scaler from the SWH plugins.

The mult parameter is the pitch coefficient, range from 0.5..2, default 1.

wildnoise/noise split index seed repeat_bytes

Inject random noise on the image.

the wildnoise version gives a harder version than noise.

Parameters:

  • seed, Random seed
  • repeat_bytes, Amount of bytes to preload with random data and repeat throughout the image slice

rotate deg bgfill

Rotate the image by deg degrees, filling the resulting triangles with bgfill.

bgfill is a hex string, e.g #000000.

embed split index path_to_file

embed an audio file in the given image. the file is opened with libsndfile, which means some formats, like mp3, will not be opened.

quicksave

Save the file on the same directory of the file specified by load, but with a suffix on the filename (before extension).

Doing consecutive quicksaves will not overwrite any files, the suffixes will just be different.
