Micro and Ableton external sound card problem

[LARSEN ARSEN]

Good evening, I have a voice recognition problem and sound recording with an external audio signal card when I dial on Ableton. I looked for help on the Internet. I am a beginner on the question.I do not know to choose between a new external sound card digital signal or a preamp or a DAC that is to say a converter? that's why I'm asking you for help. Arsene
