"""
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 simultaneously.
Can be invoked from CMake, pytest, coverage or directly.
Uses util_multimode_tx.py and util_multimode_tx in separate processeses to perform
the audio tests.
