  Antworten mit Zitat      
SCILAB ist klasse!!!

Der Skript läuft unter Scilab 6
Eine Audiodatei, Kanal 1, wird je Sekunde analysiert. Die gesamte Audio-Datei kann von Sekunde zu Sekunde durchgeblättert werden.
Die entsprechende Sekunde wird in folgender Weise analysiert.
Grafisch angezeigt werden Wav, Gleichspannungsanteil, FFT, Leistungsspektrum, und mit der FFT wird das ursprüngliche Wav Signal wieder berechnet. Mit einstellbarer oberer Grenzfrequenz.

Code:
// Signalanalyse 6
mclose('all');
clear;
xdel();
z=struct('wa',0,'ft',0,'ftl',0,'ftr',0,'st1',0,'st2',0,'lz',0,'g',0,'da',0,'pf',0,'re',0,'sf',0,'pfda',0,'info',0,'vs',1,'h1',0,'f1',0,'h2',0,'f2',0,'h3',0,'f3',0,'h4',0,'f4',0,'h5',0,'f5',0,'po',0,'fi',0);
