Sound issues in Flash Player 10
We thought it would be better to give this hint to our customers before the questions start coming.
Flash Player 10 distorts sounds sampled higher than 44KHz when using the loadSound function within AS2 – which is the version of ActionScript we used to create our file.
The solution is simple, encode your files to a value lower than 44KHz. You can read more about this issue here:

Hope this additional info helps in case you found yourself having issues with your sound files and the Flash Mp3 Player.
