X7 MP4 AAC audio quality

I have spent all day experimenting with this problem so it's time to give up and ask for help - please!

When I save a video in MPEG-4 it uses AAC audio encoding. The result is not perfect - even on the best settings there is a faint high-pitched babbling twittering distortion that is intrusive on quiet clips.

When I save the same VSP in other formats, like MPEG-2, AVI options or WMV, the sound is as good as the original clips.

I want to use MP4 as it works well on iTunes, iPhone, YouTube and Vimeo etc - but not with bad sound. MP2 would be OK but iTunes doesn't read it.

I have tried out many settings and file types but always the same result.

You can listen to examples on youtube - best with headphones to hear the faint distortion.

Is there a way to change the audio encoder? Or do you have other suggestions?

I am using Windows 10 with VideoStudio 17.1.0.22 (32bit Pro)
