Details:

The help for audiorecorder states 8 bit mono audio at 8000 Hz sample rate as
default.
This is also the Matlab default.


>> help audiorecorder
'audiorecorder' is a function from the file
/usr/local/share/octave/5.0.1/m/audio/@audiorecorder/audiorecorder.m

 -- RECORDER = audiorecorder ()
 -- RECORDER = audiorecorder (FS, NBITS, CHANNELS)
 -- RECORDER = audiorecorder (FS, NBITS, CHANNELS, ID)
     Create an audiorecorder object recording 8 bit mono audio at 8000 Hz
sample rate.


But current audirecorder initializes to 16 bit stereo at 44100 Hz.


> recorder=audiorecorder

recorder =

audiorecorder object with properties:

  BitsPerSample =  16
  CurrentSample = 0
  DeviceID = -1
  NumberOfChannels =  2
  Running = off
  SampleRate =  44100
  TotalSamples = 0
  Tag =
  Type = audiorecorder
  UserData = [](0x0)


Perhaps this was chosen due to 
bug #44305: audiorecorder (8000, 8, 1) returns corrupted audio stream
