XcorrSound

XcorrSound er et program til at finde overlap mellem to forskellige wave filer.

Pakkevejledning

Her beskrives hvordan man kommer fra kildekoden til en pakke der kan bruges i installationsvejledningen.

Følg først installationsvejledningen på en maskine der kan bygge programmet.
Kør tar -cf xcorrSound.tar xcorrSound
Nu kan tjærebolden distribueres.

Installationsvejledning

Beskrivelse af hvordan man bygger og installerer programmet på en given maskine.

svn export https://merkur.statsbiblioteket.dk/svn/scape-xcorrsound/tags/xcorrSound_v1.01

Go to the 'xcorrSound/fftw-3-2-2' folder.

Run the following

./configure --prefix=<fftw>
make
make install

where <fftw> is the path to where xcorrSound_v1.01 was checked out. fx /home/larm/jsn/xcorrSound_v1.01

go to the 'xcorrSound' folder.
Run
```
make xcorrSound
```
Test that it works: (should print out how to use this tool)
```
./xcorrSound
```
