my fix for Audio "Hiss" after converting to vcd/sv

THis is a repost from another thread. I thought it might be of help.



I had the same "hiss" problem. I am capturing HI8mm through "firewire" using "dvio" and "sclive" at 720x480. I then use Tmpgenc to convert to VCD and/or SVCD. The captured AVI file sounded great. But the VCD/SVCD had the "hiss".
I had to use "virtualdub 1.4.13". I would open the AVI file with virtualdub then clik on the "file information" to see the audio info. It showed 32000HZ 16 bit stereo. I guess Tmpgenc has trouble converting the 32khz audio into 44100hz. To eliminate the "hiss", clik the "audio" tab in virtualdub then clik "audio conversion". Then change the "sampling rate" to 441000hz. clik ok. then clik on "file" then clik on "save wav". Name the wav the same name as the AVI (i do). virtualdub will then create a new wav file for the AVI. (the avi still has it's embedded audio)
THen when you use Tmpgenc for vcd/svcd, just use the avi and it's new saved "wav".

THis worked for me.
