Default Audio recording

I was trying to record audio with the Lumix ZS3, which stereo recording features was one of the main reasons I bought the camera. To avoid image wasting I covered the lens. Then I placed the camera on a tripod pointing to the harp. The piano is an old Steinway with a lot of mechanical sounds. And the ZS3 microphones are omni directional, so they catch sound everywhere around.

The AVHCD Lite files resulted in about 330 MB for 3.16 minutes of video. A lot! So I tried JPGA video an reduced the recording quality. That ended up to 170 MB. Too much again. I went very low video quality, which I supposed would not affect the audio quality (and I was right) and the file was just 79 MB. The file is a .MOV file.
I uploaded the file in YouTube using PhotofunStudio software and a lot of sound artifacts appeared:

I thought it was the software. So I uploaded again directly from my PC to YouTube. Result?: the same artifacts.
So I decided to upload the file using Megaupload:

No artifacts.
Any advice about using an hybrid PS to record audio are welcome.

If all you want is the sound in a small file why don't you just use a conversion program like Super (http://www.erightsoft.com/home.html) to create an mp3 from the video file?

Your file compresses down to a 3MB 128Kbps audio only mp3 file with Super.

Some clue about the sound artifacts in YouTube? Could it be the .mov file?

It may be that youtube has a problem with converting AVCHD lite video files which is why I suggested changing the format something else.
