Re: 1. MP3 or AAC mixing in compressed/coded domain (2)

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.

Vegas is capable of editing both audio and video. Don't care about the
video side, just work with audio.

having for example a ten ours MP3 stereo recording

If that is your problem, then clearly Audacity isn't the way to go. 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.
