This repo provides the utilities to create audio files (.wav) for performing the Conconi Test [1].
The initial speed and end speed can be specified (in km/h). There will be a beep every 25th meter, and every 200m the speed is increased by 0.5km/h, which coincides with a higher toned beep.
For more info:
python -m create_audio_file -h
python -m create_audio_file --start_speed 12 --end_speed 22
Conconi 10km/h
Conconi 12km/h
Conconi 14km/h
