Trouble with split stereo track and make mono

Hello all,
I’m using 2.1 and I’m trying to take a stereo track, split it, delete the left track and take the remaining right track and make it mono so that it comes out of both speakers. Problem is that when I do this the sound still only comes out of my right speaker. I’m at a loss and I’ve tried everything I can think of and haven’t been able to find satisfactory instructions anywhere else. Please let me know what you think I should do.

It should be select the drop-down menu to the left of the show timeline > Split Stereo To Mono. [X] Delete the bad track. The remaining track should play to left and right…

If that doesn’t work, you may have sound system problems. Here’s a 39 second sound test.

(Left, Right, In-Phase, Out-Of-Phase Test, 48k/16, WAV 7.3MB, 39 seconds)
Simple but for the end.
The last segment is intentionally damaged by flopping
the electrical phase of only one side.
I may sound like I’m in a deep hole
or possibly coming from behind you. On
mono sound systems I may vanish completely.
You’re in trouble if the wrong segment does that.
Concert Hall Simulators may produce weird effects on
all the segments.


Audacity version numbers have three parts, for example 2.1.0 or 2.0.1. All three parts are important. If you have “2.1” then it is not a genuine version.

My version is 2.1.0. I found my error. I incorrectly clicked “split stereo track” instead of “split stereo track to mono”. Thanks to you both.

Hi I’m here in the future 2024 and I am trying to split tracks toa left & right channel. When I click split stereo track it doesn’t call the new tracks left & right but calls them both mono. I’m not clicking on Split to Mono.
I’m trying to invert one side so I can remove vocals from track
I’m on version 3.4.2

There are two sliders to the left of the waveform. One shows - & + (for gain) and the other shows L & R.

Try Effect → Special → Vocal Reduction and Isolation. Choose the Remove Center to Mono option.
