  1. I am attempting to convert an ogg file to svcd. I used decompress.exe in avi2vcd, then saved the audio as a wav using virtualdub, 44.1khz. The sample I converted using tmpgenc yielded mettalic sounding audio. SOunfds like it happens in the high frequencies. Are ther any free programs that can get rid of this distortion?

    is tmpgenc set to high quality. Otherwise ssrc or tooLame might help. Both are addins for tmpgenc

  3. Found a solution. I entered the decompressed avi into avi2vcd which uses besweet to yield an encoded mp2 which gets rid of all the distortion. Takes a very long time to encode the audio, but it is well worth it

    Shouldn't take more than 5 minutes? I don't think I've ever spent more than 10 minutes on SVCD audio, and that's going from AC5.1 down to surround MP2. I do have a number of OGG's, so maybe I'll give that a try....

  5. oops...mistyped.

    To get distortion free audio (metallic sound) when converting an ogm divx to svcd, the following method worked great for me:

    1.Take the original ogm encoded divx file and use the decompress.exe program in avi2vcd.

    2.Then take the resultant decompressed file and enter it into DVD2SVCD(under the conversion tab). BeSweet within DVD2SVCD will extract a wav, then encode the wav into an mp2.

    After besweet is done, I abort dvd2svcd so I can test encode a sample in tmpgenc, using the resultant encoded mp2 audio.

    THe distortion and metallic sounds are eliminated!!!!

    Previous unsatisfactory methods:

    If I use a wav extracted from the decompressed file using virtualdub, I get the distortion and metallic sounds. Even if I use that wav and encode to mp2 using tmpgenc, I still get the distortion. THe distortion won't show up if you play the mp2 alone.....but it will show up in the encoded mpg using tmpgenc.

    Besweet using dvd2svcd is the only method I found which gets rid of the metallic distortion.

    THis question appears from time to time and I had not found a satisfactory answer. Hope this helps others.

    Thanks

  6. SOmetimes dvd2svcd won't extract all the audio, perhaps only 2 minutes. In that case, I use another method. The key to not getting a metallic distorted sound seems to be a raw wav extraction. I use virtualdubmod.exe to save the wav from the audio stream, and input that into besweet using the settings dvd2svcd uses.

    If I use regular virtualdub to extract the wav, and change the sampling rate, then the distortion occurs. Changing the sampling rate should only occur in besweet. Haven't tried other resamplers yet. I can't find any method of eliminating the distortion once it occurs, so usng virtualdubmod is the best way to get audio that sounds just like the ogm audio.
