Digitallife USB Audio Grabber Works on Raspberry 3B+?
Audacity Official System Requirements
We recommend using the latest version of GNU/Linux from your distribution that is compatible with your hardware specifications. Audacity will run best with at least 1GB RAM and a 2 GHz processor.
Because Audacity was originally written when computers were less powerful, you may be able to run it on much less powerful hardware too. Simple recording is possible on 700 MHz Raspberry Pi, using a USB Microphone. However, Pi operating systems are not officially supported and Audacity may be less stable on them than on desktop operating systems.
Even Audacity officially does not support Pi, but still we made tests on Raspberry Pi 3B+ with Digitallife AV202 USB Audio Grabber. It can make some simple audio recordings.Here you can download the Video for your reference. Testing Download
