"""
|
|
Test small multiple-burst messages over a high quality simulated audio channel.
|
|
|
|
Legacy test for sending / receiving frames through the codec2 modem
|
|
and back through on the other station. Data injection initiates directly into
|
|
codec2 API. Tests all three codec2 data frames.
|
|
|
|
Can be invoked from CMake, pytest, coverage or directly.
|
|
|
|
Uses util_rx.py and util_tx.py in separate processeses to perform
|
|
the audio tests.
