thanks for all the answers. I am asking about mixing directly in compressed format. some reasons to pursue that:2. it's take too long to re-encode mp3 file after mixing in pcm format, which is unacceptable for some real-time (or close to real-time) application.
1. each time you uncompress edit and re-compress, you loose audio quality. thanks. Yadong Quoting Eero Aro <arox@xxxxxxxxxxxxx>:

However, Yadong didn't talk anything about large files in his question. He just asked about software that could mix two compressed audio files together. Eero
