Export Multiple WAV's - stereo and mono

[HugoCarvalho]

Hi everyone,

I have a audacity(1.3.12-beta) project (aup) that has 5 tracks -- 2 of them mono, and the other 3 stereo
track1-mono
track2-stereo
track3-stereo
track4-mono
track5-stereo

When I export them, (WAV signed 16 bit PCM), they export those 5 tracks.
The problem is that track 1 and 4 (mono in the project), becomes stereo in the wav's (1411kbps).

So, what can I do?

(All tracks in the project are 44100Hz 16-bit PCM. 3 stereo and 2 mono.)

I think it's a bug.

What version of Windows are you using?
If you have a project that in entirely mono tracks and use Export Multiple, what happens?

I'm using WIn 7 Pro (32-bit).

Also, i tried right now the 1.2.6 and it went okay.
The aup is :
1-mono
2-stereo
3-stereo
6-mono
7-mono

exported it as WAV and it went Ok: 7 files, ones having 1411kbps and others 705kbps (stereo and mono).


Now: the same exporting muitlple (same aup file and everything) with the 1.3.12-beta

but now its different, all mono :S all the 7 tracks in mono.
Audio: PCM 44100Hz mono 705kbps [output]


EDIT: tested on Win XP SP2 and the same thing happens..
i also tested just having two Stereo tracks: it exported 2 stereo tracks Ok (1411kbps)
3 mono tracks: 3 mono tracks OK (705kbps)
1 stereo track and 1 mono: 2 stereo tracks...

So that's the problem, if all them are the same (all mono, or all stereo) its perfect
But if i have mono and stereo tracks there it exports all them mono or all them stereo

EDIT2: tested exporting the same thing (1 stereo and 1 mono) in FLAC and it became in mono again.
