[b]Tmpeg Audio Problem[/b]

[fmayjmd]

I have some problem with my MPEG files. I've done editing using Pinaccles Studio save as AVI then encode the AVI files to MPG through Tmpeg. The problem is audio quality is good on AVI files but after encode to MPEG, the audio sound quality no so good. Anybody can help me ?

Depends what you mean by 'no so good'. The problem I have with TMPGEnc's audio is the volume comes out too low with the default settings. I turn on the Normalize setting and that helps alot.

DVantrease, I means the sound quality not good. Popping sound. What should I do ?

You say you are converting avi file to mpg using Tmpgenc but dont give any other details. My guess would be that your source avi file (the output from pinaccle Studio) has audio with one data rate (48Khz?) and you are using TmpGenc to produce VCD format Mpeg1 audio at 44.1khz (or at leats a different sample rate than the .avi audio). Whichever way you are going, TmpGencs audio sampling rate conversion is not very good quality and would probably explain your problem. One solution is to open the .avi file in virtualdub. On the audio menu select full processing and then compression. Select PCM from this dialog (no compression) and change the samplig rate here to whatever is required by your Mpg (VCD 44.1khz, DVD 48khz SVCD?) and save as a wav file. Use this as the audio stream in the TmpGenc input and things should improve. Other programs can probably do an even better job of converting audio sample rates, such as soundforge (whic I use sometimes) and, I think, BeSweet, though I havn't tried that one myself.

Good Luck
