Host Forum: Sonic Visualiser / Extracting text files from audacity OR sonic visualiser
« on: January 26, 2010, 19:54:52 »
Hello, all!
I am attempting to extract data regarding the waveform of audio files in a .txt format. I saw bobonofx's post regarding doing this with the data for audacity:
$ cat test.txt
1.223 2.1543 sourceA
2.542 14.133 sourceB
3.161 0.041 sourceC
$ cat rewrite.pl
while (<>)
{
my ($a,$b,$c) = split /\s+/;
$b = $a + $b;
print join " ", ($a,$b,$c), "\n";
}
$ perl rewrite.pl test.txt
1.223 3.3773 sourceA
2.542 16.675 sourceB
3.161 3.202 sourceC
$
THis information is, specifically, for use with 'perl' language and sonic visualiser. Can anyone give me a step by step instruction about how to extract this waveform data to a .txt format? I have virtually no knowledge of computer programming.
