Audacity flow

[aoinc13]

It's unclear to me how this plugin works.

1. Start with a binary file of modulated IQ data. (what format is expected? signed 16bit, complex?)
2. Select Import raw data to import the binary file into Audacity
3. Select values for Encoding: signed 16-bit PCM, Byte order: Little-endian, Channels: 1 Channel(Mono), Start offset: 0, Amount to import: 100%, Sample rate: 500000.
4. Select all of the data by typing cntl-a.
5. Select Effect from the Audacity menu and click 'Demodulate IQ signal'
6. Expected outcome - a demodulated signal that can be played in audio?
