Compressed Audio

Davewil wrote on 8/8/2005, 5:56 AM

I use DVD Architect to burn TV programs to DVD. DUring the rendering process an "information" message pops up alerting me that the audio is being compressed. When I play the DVD, voices come out a bit distorted especially when people speak loudly. Has anyone else encountered this?

Any suggestions as to how to avoid voice distortion?

thanks

you need to provide more info on how it was captured.

If you got illegal TV shows off the net, for example, they would be using a non-DVD compliant audio format & that's why they would need to be recompressed.

I recorded the programs in Mpeg-2 using Snapstream Beyond TV.

I think this uses MPEG audio, which some, but not all DVD players can play. In order to give you a 100% compliant audio stream, DVDA re-compresses to AC-3.

It would be nice if DVDA had the option to let you use MPEG audio, but it doesn't.

You could try using Vegas to do the MPEG to AC3 conversion. Drag the MPEG file onto a Vegas timeline, choose Render As..., and pick Dolby Digital. Use the resulting file for the audio stream in your DVD Architect project.

They use the same AC3 encoder, though, so I'm not sure sure there'd be a difference.

I also make DVDs from shows I've recorded using an Haupaugge tuner card and SageTV. Have never experienced any distortion in the audio, though, whether I did the AC3 rendering in Vegas or in DVDA. *shrug*

we don't know how the audio is captured yet. it could be distored on capture. it could be crappy mpeg audio encoding settings.

we need that information.
