[CC17] How come I can't lower the bitrate of a multitrack mixdown below 96Kbps when exporting?

*quick disclaimer*

I'm super new to Audition, and have only just started using it. So I'm totally open to suggestions and alternate ways of accomplishing what I'm doing!

Alright, so here's what I'm trying to do.

I have a super old audiobook that's split into several tracks (mp3 files), and I want to combine into one single file.

I've figured out how to do this by importing all in Audition, selecting all, and adding to multitrack mixdown.

Then I export that to mp3.

The bitrate of the source files is 32Kbps, but when I export from mm I can't go below 96Kbps.

I found if I do "Mixdown session to new file", and then export file, I can go down to 32 (and beyond), but that takes a really long time, and I feel like there must be another way..

How can I do this better?

Or is the a simpler way to just merge the files?

Thanks in advance!

    In order to join all the .mp3 files into one in Audition they have to first be decoded to .wav format which is Audition's native format. Then the joined files are re-encoded to .mp3 which is what takes the time and also causes the audio to lose even more of it's fidelity by doing so. A better method is to use an .mp3 joining app which will join them altogether without the decode/re-encode stage.

    Ahh okay, that makes a little more sense now.. I'd tried a couple of free tools like that, but it just seemed ridiculous to me that Audition wouldn't be able to do it "better". I wasn't aware that .wav was Audition's native.

    Thanks much!!
