Can an AC3 file be improved? How to filter audio quality?
I'm working on some homemade DVDs that I recently got, and so far on the ones I've gone through, the audio is already in AC3 format. However, a few of the DVDs still have hiss that I'd like to remove.
Since the audio is already in AC3 format, can I still restore that audio, or do I have to just keep it how it is? If I'm able to restore the audio, how do I do that? I've only restored audio and then transferred it to AC3 format, I've never started with AC3 format, and then restored it. |

I convert AC3 to WAV using Goldwave, because I have an AC3 codec installed in Windows XP. It's quicker than most other software. The freeware Aften converts to AC3, but I don't remember if it converts AC3 to WAV. It might. Same for BeLight. Avidemux can probably convert AC3 to WAV. I don't think Audacity opens AC3 -- it won't on my computers. I edit in Sound Forge. Sound Forge 9 can open AC3 directly, though I still prefer to give Sound Forge uncompressed WAV files because the program works quicker without the decoding processes. |
