| Post subject: | Extracting audio from recordings |
Hello all, I wanted to extract the audio portion of a recording, and was able to do so with ffmpeg, converting to a .wav file for easy import to Audacity. Unfortunately, however, the program shows a stereo flag in LinHes, but ffmpeg would only produce mono output. As far as I can tell, ffmpeg has no commands for stereo/mono output, what goes in is what comes out I guess. But I must be missing something here. Any ideas? TIA, --Bud |

On your LinHes box there should be a script at /usr/LH/bin/myth2mp3 that will convert a recording to an mp3 and can be used as a User Job from within Myth. From memory I believe that -ac 2 will force ffmpeg to 2 channels but check the man ffmpeg to confirm. Britney |

TIA, --Bud I've used mplayer in the past for extracting soundtracks of movies I had and it was exceptionally easy.
