问题 I am developing a system as an aid to musicians performing transcription. The aim is to perform automatic music transcription (it does not have to be perfect, as the user will correct glitches / mistakes later) on a single instrument monophonic recording. Does anyone here have experience in automatic music transcription? Or digital signal processing in general? Help from anyone is greatly appreciated no matter what your background. So far I have investigated the use of the Fast Fourier

问题 I am using the Librosa library for pitch and onset detection. Specifically, I am using onset_detect and piptrack. This is my code: def detect_pitch(y, sr, onset_offset=5, fmin=75, fmax=1400): y = highpass_filter(y, sr) onset_frames = librosa.onset.onset_detect(y=y, sr=sr) pitches, magnitudes = librosa.piptrack(y=y, sr=sr, fmin=fmin, fmax=fmax) notes = [] for i in range(0, len(onset_frames)): onset = onset_frames[i] + onset_offset index = magnitudes[:, onset].argmax() pitch = pitches[index,
