How do I change the bitrate??

[schpeck]

I have a 48 kHz audiofile (WAV format).
How do i convert it to 44,1 kHz without changing the runningtime.

Load the .WAV file into an audio editing program, such as GoldWave or CoolEdit and simply select Uncompressed PCM (WAV) format at 44,100Hz.

Changing this audio FREQUENCY in no way affects the running time...

No.

That didn't work. But I used a winamp plug-in and created a 41000 Hz wma-file with the exact same runningtime. How can I convert that file to a regular wav file??

"That didn't work."

Since that is a VERY routine conversion with that software, i can only conclude that you haven't used it properly...

I'm sorry.

My bad. Your right, I'm wrong. Guess that's why they call it junior member. Did it right this time and it worked.
But that didn't solve my original problem. I wanted to change the frequency (got it right this time) because I thought that would help synchronise the audio and video (in a VCD-file I'm trying to make with TMPG). It didn't. The video is still a half second behind. The wavefile and the avifile has the exact same running time. (I also tried to use the avifile as audio source with the same result)

Is there something I'm doing wrong or is it just some avi-files that's impossible to convert in sync??

PS Thank's for the help on my previous question by the way=)
