I am using this app from USB.
Though I tried use this app for the first time, the below dialog comes out.
I am in trouble with how to deal with it.
I guess this one is from opening sound device.
How I make the input device settings and the project sample rate?
If my guess is right, please show me how I organize them.
Otherwise please point me out alternative
Are you using an old version of Audacity? The current version is 2.3.2, and it is available via the Audacity website: https://www.audacityteam.org/download/windows/
The current version will probably not solve the problem, but it should give a better error message to help us identify the problem.
Today, error dialog never comes out, I did it properly.
The current version is 2.3.2
Can I take it from USB or Firefox or Chrome adon not via the Audacity website?
I don’t understand what you are asking. If you want to download the current version of Audacity for Windows, visit this page (in your web browser) and follow the links to the file download: https://www.audacityteam.org/download/windows/
