Movie Maker trashing 44.1kHz audio?

I'm using Movie Maker Version 2.1.4026.0, on XP Professional SP2.

Brief synopsis of problem:
- imported AVI from a DV camera via Firewire.
- added audio from a 44.1kHz WAV file.
- set the audio balance to be 100% from the WAV file.
- saved the movie to hard disk as DV-AVI (PAL), 30Mbps.
Result: audio full of unacceptable artifacts (background
ticking/raspyness, some ringing on slow piano tones).

Second attempt: as before, but used a 48kHz WAV for the audio track.
Result OK.

Hypothesis: Perhaps DV-AVI files require 48kHz audio, and Movie Maker's
sample rate conversion is (seriously) flawed. Only way to preserve
decent audio quality is to use 48kHz throughout.

Is this a reasonable conclusion, or am I missing something else:
perhaps some configuration issue in Movie Maker?

WAV is MS Win Audio Visual file type, and the sample
rate you quote 44.1khz, indicates it is actually a cda, not a wav.
You ripped the track from a CD?

You've summed it up, though it's not a "flaw",
simply that WMP is limted in many areas, and
it's compatibility with many file types is restricted.
Converting a 44.1khz cda track to MS WAV is easy
and there will be no discernable sonic differences.
It is simply a compatibility issue.

Thanks for the response. I do realise that converting 44.1 to 48kHz can
be done well (by programs such as Adobe Audition, etc). That's why I
was kind surprised that Movie Maker made such a dog's dinner of it. But
no problem: I'll just make sure any 44.1 audio gets converted first,
before pulling it into Movie Maker.

Yes, Movie Maker audio resampling seriously sucks. You need to
pre-convert the audio before importing.
 
I found this to be a good interesting exchange of posts, and added the info
to my Problem Solving > Audio Issues page....

and I think it'll make a good subject for a newsletter...

thanks
 
finally, it seems like someone else is having somewhat of the same problem as
me...after i save my movie (DV-AVI) my audio clips sound terrible (before,
they were perfect)...the conversion process is way off....what did you find
out to solve the problem? i'm making my son a MAJOR project of his life and
i've worked months and months on this....help, please if you can
 
please tell me how to convert the audio files? tell me how as if i were a 1st
grader. (ha) and how do you know what the khz is for audio files?
