I Have a movie sample with audio transcription (For Blind People- There is a narrator explaining what is going on in the movie). I want to extract that.
What i so far tried was:
1- I have the sample without the transcription as well so i just imported both samples in Audacity. Inverted one and mixed. But it simply doesnt work ( Normalization is also applied)
2- I tooke the sample with audio description. splitted to mono, Took one channel and inverted. and mixed again. Now i have the movie without audio transcript. My intuition was that if i invert this result file again and mix it with the Actual one the other sounds should cross out and i would have the Narrator sound. But it did not happen! what shall i do now ? any suggestions ?
I have checked the following links so far :
