如何用python在提取音高的基础上利用Essentia合并音符

您可以使用Essentia库中的PitchMelodia算法来提取音高，并使用Essentia中的音符合并算法来合并音符。以下是一个示例代码片段：

import essentia.standard as es

# Load audio file
audio = es.MonoLoader(filename='audio.wav')()

# Extract pitch using PitchMelodia algorithm
pitch_extractor = es.PitchMelodia()
pitch, confidence = pitch_extractor(audio)

# Merge notes using NoteMergin algorithm
note_merger = es.NoteMerging()
notes = note_merger(pitch, confidence)

# Print the resulting notes
print(notes)

请注意，您需要安装Essentia库才能运行此代码。您可以使用以下命令在Python中安装Essentia：

pip install essentia
