Can anyone suggest a simple program to edit audio track?

[Nawtwrong]

I have several avi files (Music videos) where the soundtrack is bad quality.

All I want to do is replace that track with a better quality version.

I know I could use virtual dub, but the audio track needs to be adjusted
so it will sync.

Any suggestions?

Thanks!

virtualdub.
You can adjust sync there too, click Audio, Interleave, and set the delay (bottom portion of the box).
Use negative numbers to get audio to start earlier.

Hi, thanks for the reply.

I did try that but ther's too much trial and error involved, I really need something with a timeline if possible, plus I need to output to MPEG 2.

mpeg-2 is a video format.
Doesn't matter what the output is, you can make an MP2 audio in your encoder.
Audacity, Goldwave, Soundforge...take your pick.

I want to output the entire video as MPEG-2 with audio as MP2 or PCM or ideally dolby digital.

At the moment the files are in avi (XVID/Divx) format.

Use your encoder to encode your files to DVD compliant MPEG files NTSC or PAL. The encoded file will have MPEG2 video + AC3 dolby digital audio to your liking.

Extract the wav from the musical files with VirtualDub, then load it into Audacity, then import the good version in Track 2 (one click!), and line up the start of Track 2 with Track 1 via the time-shift tool (another single click of the mouse!). If it's a different duration, use Audacity's "Change Tempo Without Altering Pitch" effect or the "Change Tempo With Altering Pitch" until the 2 tracks match. Then delete Track 1 and save Track 2 as a wav file, convert with ffmpegGUI if necessary, and combine with converted m2v video clip in your favourite free authoring program!

EDIT: You might wanna encode the avi too HA

How would you know that? Most encoders don't do AC3, they do mp2, unless you have a plugin, and specify it.

Yes reboot I agree. Maybe I was in a different frame of mind when I wrote that. Maybe some other authoring thing was going in my mind. I stand corrected.

Brain fart. I get them all the time too!

The solution is Vegas, it is simple but not cheap.

[Nawtwrong]

You're right, the solution is Vegas!

I managed to blag a copy of a friend, a Sony version and it's excellent, did the job fine and it outputs to MPEG 2 with AC3!

Thanks for your help!!

You are in breach of the forum rules and are being issued with a formal warning. If you want Vegas, buy it. I think there's even a free trial.

The problem comes when the audio won`t line up with the video , a hit and miss stretching is a pain in the arse (0.1seconds out will show on lip sync), I`m half way through a tutorial on this (replacing a vhs cap audio with cd sound) , hope to finish it soon .

I've found Goldwave is very handy for that.
Cann't wait to see your tutorial. Thank you in advance for the effort.

My tutorial of "Replacing a Music Videos Sound with CD Audio" has been written and input to the board I am assuming it requires verification first before it appears on the boards New Guides list , it involves some maths and some fiddling about , but after you understand what it involves its easy .
I mention it here as interest in it was shown in this topic about it (as it is about music videos audio) .
