Goldwave AC3 codec

[shadow_cruiser]

I can't seem to get goldwave to accept my audio tracks from ffmpeg or avi2wav. It opens in the player but when i want to batch process to match the volume between 13 tracks it says "No codec is available to encode or decode the audio format".

I have the latest version of lame with the acm file. How do you register lame codecs to be used with goldwave?. I copied the files over to goldwave folder but that didn't work.

Any help would be greatly appreciated. Thanks

It doesn't open AC3. The end.

You need to install ac3 filter, in the tools section, and it should work fine.

edit:
Goldwave will open AC3, but will not encode AC3. You can open an AC3 file, edit it and save it as wav and then use another program to re-encode to AC3, if that is your intention. And to encode with lame, you need to put the lame_enc.dll in the Goldwave directory.

I do have AC3 filter installed. Along with the latest lame and latest k-lite codec pack.

What I'm looking to do is extract the raw audio from tha avi file, already done with virtualdub. Audio file from the avi is mp3 format originally. Then match the volume through 13 tracks(Goldwave) and save as ac3.

I'm personally not looking to encode 2-3 times as I think it will lose quality.Thats only the last resort unfortunately.

Even when I use virtualdub to demux the audio, it saves as wav extension with mp3 codec. When trying to batch process through goldwave it says codec not installed?

Any other suggestions?

Why don't you just use Goldwave to batch straight from avi to wave?

[lordsmurf]

If you extract the video out to uncompressed WAV, you will not lose quality.

So you are not trying to open AC3 in Goldwave, but encode AC3--doesn't do it.

Besweet will transcode mp3 to AC3 and has batch. But to match volume, you could load each file into Goldwave, match volume, save as wav and batch encode to AC3, with Besweet.

Thanks guys for your help. I fixed it but not through the methods you mentioned.

I first re-extracted the audio from the .avi files which turned out to be mp3 format. I then used a program called mp3gain(awesome freeware program) to match the volume of the tracks together. I then used ffmpeg to batch the files to ac3.

Note: MP3gain doesn't re-encode the files and keeps it in its original format.

Good that you got it worked out. MP3gain does appear to be a quick method, although I don't like a program that alters the original, but it does give the option to undo. It does look to be a useful program.

Goldwave would get you to the same point, just one extra step of creating wave files, and still only one re-encode to AC3.

In the feature list of the program, it says mp3gain does not alter the original. I believe that also since it was only couple seconds or so to change the volume in the file and save it. These are 30mb audio tracks.

I tried goldwave but it said unsuspecting error on a few audio tracks. I checked with a couple programs to see if there were any errors,bad sectors,etc and nothing showed up.
