TMPGenc audio problems can anyone help?

[status66uk]

ive captured a music video to avi using virtuadub, the audio is exactly the same as my video excellent quality, bearing in mind it has a little bit of hiss on it which is pretty normal, but after ive encoded it with TMPGenc to dvd mpeg2 standard the audio sounds compressed and much worse than the sound on the avi file i cant understand whats causing this, i use 2 pass VBR 7000 to encode, i dont think its my capture settings so it must be a problem with tmpgenc

has anyone experienced this and what shall i do to rectify it?

thanks in advance

You could try using an external audio encoder like tooLAME,MAEnc, or SCMPX. You can select the encoder once it is downloaded in TMPEnc under Environmental Settings.

Here is the link to tooLAME:

I read that it is one of the best external encoder.

You also might be losing quality from a sample rate conversion. tmpgenc's standard built-in sample rate converter does a pretty poor job. If you have a newer version of tmpgenc, there is an option in the environmental settings for "high quality" sample rate conversion. You can also download ssrc (linked in the tools section) and use it as an external sample rate converter.

I find that the levels going into the avi from the LD, VHS or whatever source need to be lowered before capture. Because tmpgnc can't handle normal loud levels of audio encoding to mp1 with out clipping. And second, you need to make sure the audio quality is click checked to "high" in tmpgnc. I forget where that box is to be found, but it is there, and once you check it (and input slightly lover audio level), you will be happier with the sound quality.

I had made about 4 VCDs before I found that setting, and now my discs are really nice clear stereo. Just a bit lower in level than most DVD, CDs, etc.

Hope this helps,
