Mp4 audio bitrate

I am checking my mp4 file's details which created with obs studio, I see audio bitrate value different for each one. Sometimes about 140 kbps sometimes 256 kbps. Why it is different for each file? What is the affecting reason? If it's saved 256 kbps audio bitrate, sound quality is so good. Is that possible to fix that value?
