      Description

      For 2-channel audio, the bitrate = 128 kbps; 1-channel = 61 kbps. This-in addition to ffprobe and mediainfo characterizations-confirm that audio stream is MP3/LAME-encoded, though files come down with an ".mp2" extension.

      Here is mediainfo file characterization output for the encoding settings:

      MONO AUDIO
      Encoding settings : -m m -V 5 -q 0 -lowpass 17 --vbr-mt -b 32

      STEREO AUDIO
      Encoding settings : -m j -V 5 -q 0 -lowpass 17 --vbr-mt -b 32
