tico

mechanical watch analysis on a Wav file requires gnuplot and fftw3 $ sudo apt-get fftw3-dev gnuplot

Example.

make the wav file, use 48000Hz please

a=122;rm -f out.wav; (ffmpeg -i Recorder/Voice\ $a.m4a out.wav) 2>/dev/null ; #help tico -h

use -t to get only the top of the sound

-r cuts off the last 10 seconds -l cuts off the first 20 seconds -d narrow search round max -c crosscorrelation threshold -v prints the gnuplot statement -s split tick tock pulseshape -e applies a gaussian window of s=8

generate a plot in lussen/www/tico.png and raw data

~/tico/tico/tico -l 4 -r 5 -s -e4 -d 50 < out.wav

teeth -e4 -c 0.8 -l 4 -r 4 < out.wav
