Importing MOV - Audio problems

I am importing some small MOV files into Flash. I was provided with quicktime files with the following audio format: MPEG-4 Audio, Stereo, 32000 Hz. The audio sounds great in the Quicktime movie, but would not import into Flash.

I looked at an mov I had succesfully imported with audio in the past and requested files with that audio format: QDesignMusic 2, Mono, 22050 Hz What I was sent actually had this format: 8-bit unsigned integer, Mono, 22.050 kHz This audio does import, but there is a buzz/hum in the quicktime audio, and that noise carries over into Flash.

This leaves me with a couple questions:

  1. Does the second audio format I requested / was sent unavoidably cause this noise because of some kind of compression? or does it sound like the person preparing the Quicktime file doing something that is causing the problem?

  2. Is there an audio format standard for Quicktime movies that has good quality and that imports into Flash that I should be using?

I don’t know anything about creating Quicktime movies, and audio format so I appreciate any insight you can offer.
