However, the features in the program have not changed, so explanations of how to do things are still valid.

Using AUDACITY for recording
If I launch Audacity before I do anything else, this is what I see:
On the bottom left of the screen is the Project Rate, 44100 Hz. Tony's comment (above) was:
It's far, far better to make the initial recording as a WAV file at least at CD quality (16bit 44.1kHz) - I use 24 bit 96kHz.
So what we have (which is the 'default') is fine. You can choose a different rate by clicking on the drop-down box. These are the options you get:
Now make a mental note of what is at the top of the screen. Next to the microphone symbol the default is eg. Microphone (Realtek High ...). If you click the drop-down box this is what you see:
And to the right of the microphone symbol are the Speaker options ie. what you are listening with.
If you then plug in the USB lead from the UCA202, nothing changes. No other options appear. ie. the Audacity Program does not recognise something that has been plugged in after you have launched the program.
So what you must do is to set up your recording equipment before you launch Audacity.
This time I have plugged the USB lead into my Laptop (the green light has come on on the UCA202 showing that it is powered up) and then I have launched Audacity. Now see what I get as my options for the 'Microphone'. This is what is in the drop-down box, so I have selected Line In (BEHRINGER USB ...):
You get the option Speakers (BEHRINGER USB ...) in the right hand box too, so I have clicked on this and will plug my headphones into the Behringer UCA202 to monitor my recording.
I should add at this point that you should make sure that the box to the right in the Microphone section is saying 2 (Stereo) Recording. If it says Mono, change it to Stereo.
