title: Make chunks in Audio files with overlap in python
body: <p>I want to make chunks from my audio files in order to overlap between chunks. For example if each chunks has 4 second length and first chunk start from 0 to 4 and step for overlapping is 1 second, second chunk should be start from 3 to 7.According to this <a href="https://stackoverflow.com/questions/36799902/how-to-splice-an-audio-file-wav-format-into-1-sec-splices-in-python">How to splice an audio file (wav format) into 1 sec splices in python?
  </a> ,I used <code>pydub</code> module for doing this and <code>make_chunks(your_audio_file_object, chunk_length_ms)</code> method, but it doesn't have overlap between chunks and just slice an audio file into fix length chunks. Anyone has an idea for this purpose ? Thank you</p>
