I have uninstalled and redownloaded audacity 3.1 several times. The voice saying TRIAL keeps coming. How can I get rid of this? (6/2/22) 
It’s probably a trial version of a plug-in that’s causing the message. Check to see what trial version software you have installed.
Audacity from the Audacity website is a full version, not a trial or demo version (https://www.audacityteam.org/download/)
Thanks for the reply! I have downloaded the version of the link provided and “trial” keeps coming out. I run on windows 10 64 bit. I keep downloading the installer, should I get the zip?
Check through all audio plug-ins to find the one that is a trial version, and uninstall it.
For additional insight, do a google search on
where does audio “trial” watermark come from
Has anyone figured this out yet? So frustrating! I just want to record a set 
Please try the suggestions that have already been given in this thread.
Apparently a trial-version of virtual-cable can be responsible for the female voice, (rather than a plugin in Audacity) , see … https://forum.audacityteam.org/t/voz-femenina-durante-la-grabacion/66003/7 
So I uninstalled the trial version but now I can’t record at all?
If you just want to record what’s playing on the computer you don’t need virtual-cable,
just choose WASAPI as the host in Audacity, see…

I’m trying to record off serato via DJ controller.
If the sound is coming through the computer, Audacity can record it via WASAPI.
There are free (donation-ware) virtual cables & virtual mixers if you need to route multiple inputs into Audacity, ( e.g. DJ microphone & music sources )
Hi there,
It is not audacity, but the trial-version of virtual-cable that is responsible for the problem.
Just uninstall the trail version of virtual audio cable & install the Lite version (see link below)
