Split Audio Files with Python | Guide

To achieve automatic audio segmentation, you can utilize Python’s audio processing library. Here is an example code using the Librosa library:

import librosa

# 加载音频文件
audio_file = 'audio.wav'
audio, sr = librosa.load(audio_file)

# 使用onset_detect函数检测音频的节拍点
onsets = librosa.onset.onset_detect(y=audio, sr=sr)

# 根据节拍点将音频分割为多个片段
segments = []
for i in range(len(onsets) - 1):
    start = onsets[i]
    end = onsets[i + 1]
    segment = audio[start:end]
    segments.append(segment)

# 保存分割后的音频片段
for i, segment in enumerate(segments):
    librosa.output.write_wav(f'segment_{i}.wav', segment, sr)

In the code above, we first load the audio file using the Librosa library. Next, we use the onset_detect function to find the beats in the audio. Then, we segment the audio into multiple fragments by iterating over the beats. Finally, we save the segmented audio fragments to files.

Please note that this is just sample code, and adjustments and optimizations may be needed based on specific requirements during actual use.
