Automatic Audio Chord Recognition with MIDI-Traind Deep Feature and BLSTM-CRF Sequence Decoding Model
My version of the original work so it can be used as a package
from wuyimingchroma import get_chroma
import librosa
y, sr = librosa.load(librosa.example('brahms'), sr=44100)
chroma = get_chroma(y=y)
print(chroma.shape)
