I read this post as similar…
Did you try [u]this solution[/u] to decode with FFmpeg?
Or, if you have a desktop or tower computer with a “regular soundcard” you can connect the turntable’s analog line-outputs to line-in (blue) on your soundcard and record directly into Audacity.
Or, if it has USB computer connection you can use that and record with Audacity. That would probably a USB-B connector (the square kind) or something different from the thumb drive connection.
Or, you can get a little USB audio interface such as the Behringer UCA202 or UCA222. don’t buy a regular “USB soundcard” because they are like laptops with mic-in and headphone-out.
I bought a $60 turntable
If you WANT to upgrade [u]Knowzy.com[/u] has LOTs of reviews and recommendations. Personally, if I didn’t already have a setup for recording I’d buy the Audio Technica AT-LP120XBT-USB. ($300 USD) The XBT version is the newer version of the AT-LP120-USB with Bluetooth and USB.) A better turntable will give you better sound quality, but wouldn’t spend much more than that because you’re never going to get “CD quality” from vinyl no matter how much you spend.
Knowzy doesn’t like Audacity because it’s not super-easy to use and it doesn’t burn CDs, etc. Fair enough… That’s his opinion. Audacity is a complicated audio editor with lots of features & functions, including the ability to record, and people use it for lots of different things. (It is one of the most popular open-source applications of any kind.)
