Instructions

git clone https://github.com/MPRlab/pitch-sensing.git
pip install -r requirements.txt
#Replace the installed CREPE library with the files in pitch-sensing/crepe

#Run CREPE for all model sizes, all timesteps (ms), and filters results by confidence level.
python crepe_accuracy.py

#Finds pitch detection latency for CREPE
python crepe_latency.py

#Runs CREPE continuously on audio stream
python crepe_stream.py
