How can I use python to split a mp3 file to several parts

Now, I have to split a mp3 file into several parts. I use python to do the work. But I cannot find a good library to do this job. I've already tried pymp3cut, echo-nest-remix, but it cannot work well.

So is there any better choice?

good choice might be librosa, your just split array using sample rate and desirable seconds, in example below number of seconds - 2

import librosa
import soundfile as sf


audio_file = "your_example.mp3"
y, sr = librosa.load(audio_file, sr=None) 

# chunk duration 2 seconds
chunk_duration = 2  


chunk_samples = int(chunk_duration * sr)


chunks = [y[i:i + chunk_samples] for i in range(0, len(y), chunk_samples)]

for i, chunk in enumerate(chunks):
    output_file = f"chunk_{i}.mp3"
    sf.write(output_file, chunk, sr)

I have been using VLC's python binding http://wiki.videolan.org/Python_bindings to convert videos and split into frames. VLC supports MP3 but I must admit I have not used it with audio.

You could convert your mp3s to raw .wav and use audiolab to read it in, then write out files every N frames, then convert those to mp3.
