faust2svgplot

tool to create a svg of plotted values.

usage

./faust2svgplot <your compilation parameters> <myamazingdsp.dsp> 

./myamazingdsp <-n (nb_samples)[default:4096]> <-bs (buffer_size)[default:1]> <-r (sample_rate)[default:44100]> <-s (start_at_sample)[default:0]> <-sp (split)[default:0]>

basic example

dsp code :

import("stdfaust.lib");
process = 
(
    (
        os.osc(100),
        os.square(100)*0.15,
        os.triangle(400)*0.15
    )
);

notes

• in usage, insert in <myamazingdsp.dsp> your favourite faust dsp file

the probe metadata

You can use the probe metadata in bargraph in order to plot at a different node of the dsp program. dsp code example :

import("stdfaust.lib");

SendtoOut(n) = vbargraph("[probe:%n]label%n",0,1);

process = 
(
    (
        ((os.osc(100):SendtoOut(1)),
        (os.square(100)*0.15:SendtoOut(2)),
        (os.triangle(400)*0.15:SendtoOut(3)))
        :>_
    )
);

the split option

You can split your graph in multiples graph.svg for every probe and every channel.

• usage : ./myamazingdsp -sp 1

notes

• The probes are evaluated at every buffer size end. If you want the maximum precision, you will need to have a buffer size of 1 sample (set to 1 by default)
