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.

1. Export source fra repository

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

2. Kør

   ./createtarball.sh

3. Nu kan tjærebolden (xcorrSound.tar) distribueres.

Installationsvejledning

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

1. Export XcorrSound

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

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

3. Run the following

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

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

1. go to the 'xcorrSound' folder.

2. Run

   make xcorrSound

3. Test that it works: (should print out how to use this tool)

   ./xcorrSound
