Hi there,
During the process of converting a 23.976 fps AVI into a 25 fps MPEG2 file, I need to convert the AC3 audio so that it fits the video.
I've previously used BeSweet with ac3enc to do this, but am unhappy with the results (the resultant sound is very poor).
I've found the following instructions on a better way of achieving this, but am stuck at stage one, and need some help.
1 - demux the AC3 to 6 wavs in BeSweet (no other processing)
2 - sample rate set (not resample) to 50050 Hz for each wav in Sound Forge 7
3 - resample each wav to 48000 Hz in Sound Forge 7
4 - Reencode the 6 wavs to AC3 in Soft Encode
With reference to stage 1, I have loaded BeSweet using BeSweetGUI and entered the Wizard mode (I'm a bit of a newbie on the audio side of things), chosen my AC3 input file, chosen WAV as my output, but at the output mode stage am confused with the following choices...
16bit (Six) Mono Waves
32bit (Six) Mono Waves
Should I create 16bit or 32bit waves? I have no idea?
Secondly, the wizard is adding on a -azid( --maximize ) to the end of the BeSweet command line. The above instructions recommend no other processing, so is this required, or can I leave it off?
FYI - The command for 16bit is this...
"C:\Program Files\BeSweet\BeSweet\BeSweet.exe" -core( -input "D:\Captures&Rips\conversion\Audio\Extracted_audio_1.ac3" -output "D:\Captures&Rips\conversion\Audio\Extracted_audio_1 - New - [16.01.2005] - [10.54.14]-" -6ch -logfile "C:\Program Files\BeSweet\BeSweet.log" ) -azid( --maximize )
...and for 32bit this...
"C:\Program Files\BeSweet\BeSweet\BeSweet.exe" -core( -input "D:\Captures&Rips\conversion\Audio\Extracted_audio_1.ac3" -output "D:\Captures&Rips\conversion\Audio\Extracted_audio_1 - New - [16.01.2005] - [10.59.56]-" -6chfloat -logfile "C:\Program Files\BeSweet\BeSweet.log" ) -azid( --maximize )
Thanks very much for any help you can provide.
