The Audacity link for using Ion tape player and turntable to convert to iTunes shows the necessity to download http://lame1.buanzo.com.ar/
Safari comes up with a message “can’t find the server.”
I am using macOS Mojave 10.14.6 and Audacity 2.3.2
With Audacity 2.3.2 you no longer need to download and install LAME - it is now built-in to that version (and future versions) of Audacity.
I’m assuming you got that link from ION - as it is not the link we used to provide in the older Audacity Manuals. USB turntable and USB cassette deck manufacturers are notorious for getting the instructions for Audacity wrong - “don’t ask me how I know”

Thanks. I have successfully recorded one track from an album. However, I cannot hear when a new track is about to start, as no sound is emitted from my MacBook. Which controls will allow me to monitor the sound?

“Transport menu > Transport options > Software Playthrough”.
Note that there is a slight delay (usually about half a second) before the sound comes out. Unfortunately this is unavoidable because the sound has to work its way through buffers on its journey from input to output.
Very grateful to you, Steve. I will try that.

I downloaded the newest version of Audacity and am using Mojave 10.14.6
I am using a UBS adapter
I have no idea if it is recording as after I turn on tape deck, click record on Audacity I cannot listen to what has been recorded.
How do I play back?
I clicked transport and play through and still no sound from the macbook
How do I know the cassette is actually recording
I have never done this before and would love some help
Ensure that you connect the device before you launch Audacity.
You should then see a USB device option in the Recording settings of the “Device Toolbar”: Device Toolbar - Audacity Manual
