Extracting lossless audio
Hey there!
I've got a mpeg2 video from a minidv camcorder transferred to my computer via firewire! The camcorder records the audio in PCM wave (lossless)! How do I extract the audio stream to wav (lossless)? I did look for PCM wave, but couldn't find any satisfying results... Sandra edit: When I open the mpeg2 video in mediainfo it says MPEG Audio 224kbps 48KHz, which is actually lossy? Any idea what went wrong with the lossless audio stream? Last edited by Sandra24; 29th October 2008 at 03:03. |

You may use eac3to:
eac3to input.file output.wav or for multiple monowavs; eac3to input.file output.wavs Edit:Sorry i've just realized you are using a mpeg2 camcorder; which means it makes mpa (mpg audio/ or ac3), so you have to re-encode it to pcm. But command line which i gave above is gonna work in transcoding job. Last edited by rica; 29th October 2008 at 03:29. |

sandra, i've edited my post.
I'm afraid it must be lossy since it's compressed(/encoded) to mpeg2. If it were a classical DV camcorder, you would get pcm but in your case you should transcode it if you wanna get the pcm. Last edited by rica; 29th October 2008 at 03:29. |

Or simply say what camcorder you are using. Last edited by rica; 29th October 2008 at 03:40. |

It seems not an mpg2 camcorder but a classical DV camcorder.
So i suspect of your capture/recording method. And it is time to upload a short sample. You have to capture DV as is. I suppose your capturing software makes re-encoding; that is the problem. Last edited by rica; 29th October 2008 at 04:40. |
