I ended up with the following, which avoids additional installations for 
the faac encoder in my Mint distros (using voaacenc instead of faac):

      .....

      Else If $RecordingFormat = aac Then
         pl = New MediaPipeline
         src = New MediaControl(pl, "pulsesrc")
         src["device"] = $Device
         cnv = New MediaControl(pl, "audioconvert")
         enc = New MediaControl(pl, "voaacenc")
         flt = New MediaFilter(pl, "audio/mpeg,stream-format=adts")
         snk = New MediaControl(pl, "filesink")
         snk["location"] = $TempFilePath
         src.LinkTo(cnv)
         cnv.LinkTo(enc)
         enc.LinkTo(flt)
         flt.LinkTo(snk)
     End If

     .....

Best regards
