Is there any software available which can cut a background score from a movie and make it a mp3 file .Like if we like a background score and want to cut it which method should we adopt, any software is available for this.
If you didn't understood the question , plz ask me repeat it clearly.
Well, I'm not sure into MP3,
but with VirtualDub, you can rip the audio into wav form. I'm sure then there are other programs that can convert wav into MP3.
You can get VirtualDub at VirtualDub.org
You can take the sound directly from the movie, but it will include all the other sounds, i.e. talking and sound effects over the top. There is no way to remove those. Also remember that film scores are copyright protected.
You can simply use Windows Sound Recorder. Be sure that Stereo Mix is selected under the volume properties of the recording device in audio properties; which can be accessed via the edit menu in sound recorder. You can then save it as WAV. Get audacity and LAME, open up the file and export it to MP3. Audacity can also export to the newer and better Ogg Vorbis format without LAME.
You can try VCD Cutter. That should be the ideal one for your job as it has tools to separate the video (into *.m1v) and audio tracks (into *.mp3) and save them as separate files. But as told you will get the whole audio track (i.e. with complete dialouges and background scores)
I want to have another software which can read contents from scratched disks.It can be free or premium, plz tell soon.
