extract voice from audio ripped from video

[bobon721]

original video+audio format: xvid+mp3

extracted audio format: 128 kbps 44 KHz 2-channel stereo mp3 (same as source)
extracted audio content: evil laugh or speech with explosions and other low volume noise in background

preferred output format: midi as cellphone message alert tone
preferred output content: evil laugh or speech only

Is this possible with audacity 1.2.6? If it is, how do i do it? Thanks in advance.

It's not possible with any software. MIDI does not do speech. MIDI files just tell a synthesizer what notes to play (and a bit more, but not speech) http://en.wikipedia.org/wiki/Musical_In ... _Interface

What if I use mp3 format for output? I just found out my cellphone actually supports mp3 for message alert tones.

You can install the lame software package and then Audacity will be able to export MP3 music. What you can't do is unmix a mixed performance. You can't separate the voices from of a song, the violins from a symphony, or the drums from a jazz band.
