A comparison of a 60 second recording, amateur radio, single sideband.

WAV: 5,800 KB
MP3:   464 KB
WMA:   492 KB

Comparing the audio quality of these recordings, WMA is better although the output file is approximately 5% larger. General opinion is that WMA is better than MP3 as lower bit rates.
From the Rec/Playback pane in the ribbon bar select Audio Record, the Record Active Receiver window is displayed.
  • Title - used as the filename,
  • Folder - where the file is stored,
