I need a free software with which I can mux a MP4 video with a MP3 audio

[Bovin]

I want to mux audio and video files. For that I am in need of a free software. Previously tried a software called AVI Mux but it does not have support for MP4 files.

So, please tell me few names of such softwares which meet my criteria.

ffmpeg primarily does transcoding, however you can input some video and audio and use these on the ffmpeg commandline to mux the raw streams
... -i "somevideo.h264" -i "someaudio.mp3" -c:v copy -c:a copy -map_metadata -1 -movflags +faststart -y "something.mp4"

mp4box also does it (that's it's main job)

MKVToolnix - if you can use a MKV file. Else mp4box has the GUI frontends MyMP4BoxGUI, YAMB.
