Matching transformer question

What`s the audio card microphone input impedance. Mr. google says around 1-20Kohm. So very different as with a basic receiver with 50 or 75ohm. If you know the two values, you can also plot it on paper/screen using a smithchart and use the corresponding cap/inductance to match the two. 73 Frank
