any way for downsamplig AC3 to 44100 hz ?

steve · 16th November 2001, 20:01

Hello all,

Does anyone knows a way to directly downsample an AC3 source to a 44100Hz .wav ?
I'm ripping a DVD of songs originally in AC3 format, I extract each channel to separates wave files to re-encode them into a Dolby Digital wave file (or a DTS wave file). The goal is to burn a multichannel audio CD.
The problem is that I need 44100 wave samples to do that.
I must downsample after decoding, using cool edit, but that take a long time for one song ...
If anyone knows this tip, that would be great.

Thanks a lot

Steve

i myself do lots of AC3->DTS CD conversions.
i use :
AZID for decoding the ac3.
SSRC for resampling the result to 44.1khz.
SurCode CD Pro DTS to create the DTS WAVs.
and then burn...

look for future versions of AC3toMP3 for a feature of :
48khz AC3 -> 6 mono 44.1khz wavs.

Ok

Thanks for the tip.
In the same Do you have a tip for extracting every channel in one operation ? (saving 6 differents wav during one extraction)

Thanks a lot for answering

@C0mPr355: I'm sorry.. but you were being lazy and have no right to call anyone a smart ass. Read up before you ask... I don't want this forum to become a newbie-asking-the-same-stupid-question-that-has-been-asked-over-and-over-again infested place and that includes reminding people to read up before asking in a stingy way. case closed

and there's no such directshow filter that would downsample at playback time.
