Enregistrement d'un son interne

Je cherche à enregistrer la bande son d’un film directement sur mon pc via Ardour sous windows.
Actuellement je passe par ma télé avec un micro mais la prise de son est pourri.
Quelqu’un a t’il la solution?
Merci d’avance

Ardour natively imports video files and can extract its soundtrack. cf http://manual.ardour.org/video-timeline/
To import the sound of an analog recording (say, e.g. a VHS), you should first physically plug the line out/phone out from the player or TV to the computer (with an audio interface, or at the very least with the “line in” jack plug. If Ardour is set up to record from the audio interface/internal sound card, simply recording (http://manual.ardour.org/recording/monitoring/monitor-signal-flow/ and http://manual.ardour.org/working-with-tracks/audio-track-controls/) the signal will achieve your goal.
