SVCD audio

[MrJiggy]

I just ripped a dvd to svcd. The video is perfect. The audio however has a crackling noise in the backgroud. I used dvdx and tmpgenc. What would be the best way to fix this?

TMPGenc doesn't do a great job of dealing with sample rate conversion (48kHz -> 41kHz) required by the SVCD format. One solution is to use an external application like SSRC (see the Tools list). It acts as a plugin to TMPGenc (Option-> Environmental Setting-> External Tool-> Sampling Frequency Converter).

I also get cracking in the audio when I approach the maximum bitrate of my DVD player.

Ok, so whats the best way to rip out the bad audio and put the fixed audio in? Also, i don't see ssrc in the tools section.

[MrJiggy]

can someone help me find ssrc?

I found it, but I still don't know how to just rip the audio from the dvd. Can someone help?

[EricB]

You don't need to "rip" the audio. Just put SSRC in as an external processor and it will automatically convert the audio instead of using the default TMPGenc converter.

[MrJiggy]

So are you saying I have to make my svcd all over again, using ssrc? Or is there a way i can do the audio seperately?

hrm..also consider the source audio from the original DVD. at first, i thought the crackling was due to tmpgenc's downsampling. however, i later found out the original audio has it.

i.e. when i ripped Deep Impact, i used dvd2avi rip the default track 1. however, the track was only 192 kbits/s. this track had the crackling. however, when i selected the next track, i was able to rip the 448 kbits/s audio, which had no crackling in it.

so make sure the crackling doesn't originate from the source before you go through the trouble of downsampling it externally from tmpgenc.
