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

  3. Nu kan tjærebolden distribueres.

Installationsvejledning

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

  1. Checkout XcorrSound

    svn co https://merkur.statsbiblioteket.dk/svn/scape-xcorrsound/tags/version-XXX
  2. Go to the 'xcorrSound/fftw' folder.
  3. Run the following

    ./configure
    make
    make install
  4. go to the 'xcorrSound' folder.
  5. Run

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

    ./xcorrSound

Anvendelse

xcorrSound <<EOF
ANALYSIS_FILE_1.wav
