I want to change the audio in a mp4 container and replace it with another, without re-encoding video or audio. How do I do that? Remuxing both video and audio, and mux the video with the new audiofile? Does anyone have program tips?

Yes, mymp4boxgui worked just fine. It is easy to use. I demuxed to a .h264 videofile and .aac audiofile (ADTS sound), and muxed the new sound .m4a (aac) together with the .h264 file. The reason why I wanted to exchange the sound was that the sound in the mp4 file was too loud.
