stereo width - not working as documented, I think

[returno]

I have a Sanza Fuze V1. I'm using 3.10.

I made a stereo recording that has sound only on the left track - this verified in Audacity. There is zero sound on the right. (Why I won't go into, but it is part of a larger project where some part of the recording with be on either the left or right or both.)

I want to hear the recording such that there is only sound on my left-hand earbud. I go to "channel configuration" and choose "custom". Then, I go to "stereo width". Here is where things seem to not be working according to the documentation. I was expecting this:

0% = mono, equal volume on both ear buds
100% = same as "stereo" setting - a little sound in the right earbud, left has normal sound
250% = no sound on the right earbud, left has normal sound

What I hear is:

0% = mono
95% = a tiny amount of sound on the right ear bud
100% = same as "stereo" - a bit of sound on the right ear bud
...going up = more and more sound on the right earbud 
250% = about the same as 0%

There is no setting where there is zero sound on the right earbud, which is necessary for my project to work correctly. 

Ideas?

Thats actually not what its meant to do.  Stereo width makes the side channel (L-R) either stronger or weaker relative to the mid channel (L+R). 

There is no setting where there is zero sound on the right earbud, which is necessary for my project to work correctly. 

We don't have any way to do this at the moment.  I committed a swap stereo option a month or so ago during the feature freeze for 3.10, but removed it since we were supposed to be in feature freeze.  Then i realized it wasn't well implemented and haven't had time to look at it since.  You're welcome to go through the SVN logs and see if what I had works for you.
