Cant convert 2lame MP2 to Wav

[drak23]

hello all:
Lately I've been using the BeSweet gui with the 2lame component to encode the audio portion of my captures. This has worked fine until I encounted an audio sync problem and I needed to edit the audio (source was deleted unfortunately). Previously I used TMPGEnc's encoder to create the MP2s and had no problem loading those in Goldwave.

I've tried every option but all I get is hiss when I load it in to Goldwave. I tried using avisynth and mpasource to load it in to Virtual dub (thinking I could save it back out as a wav) but I just get an error. I downloaded audioconvert and tried that but it chokes also. I read that some apps need windows media player 9 so I installed that and rebooted but no change.

What am I doing wrong here? Any tips on how to convert an MP2 created with 2Lame to wav??

The file does not appear to be corrupt, it plays back perfectly in PowerVCR(for instance).

Thanks and Regards,
Drak

I was just about to tell you to use tooLame to decode, but i just opened tooLame -h, and there is no decode function.

Have you tried GraphEdit?

Last suggestion, there is a MPEG audio encoder / decoder called SCMPX.
Its far from the best, but it seems to be the most forgiving.

Kind of a weird interface too!

Thanks for the tip - graphedit yielded the best results so far. I got a wav file but it is distorted - speeded up. I used the following filters on the original VOB:

I-Media Multiple MPEG2 Source
MPEG-2 Splitter (or Ligos Mpeg Splitter)
InterVideo Audio Decoder
WAV Dest
File Writer' ("C:\output.wav.")

I think the key is the InterVideo Audio Decoder. Know of any filters out there that specialize in decoding TwoLame?

FYI -
SCMPX worked also, but yielded the same results - distorted sound. I might be able to fix it in Goldwave but thats more effort than I want to put in to it.

I should probably post another thread for this question - but I'd like to know the recommended procedure for processing the audio of a capture. I've read TMPGEnc is not that good for audio, which is why I used 2Lame, but I'd prefer to be able to edit the resulting MP2. Any recommendations?

Yeah - don't believe everything you read about TmpgEnc audio! I find the results more than adequate. Each to his own though.

I'm starting to come around to that idea. I'm thinking that for my purposes (quality-wise) TMPGEnc is fine - and I've never had a compatibility problem with the resulting MP2.
