 AudioStretchy is a Python library and CLI tool that which performs fast, high-quality time-stretching of WAV/MP3 files without changing their pitch. Works well for speech, can time-stretch silence separately. The library is a wrapper around David Bryant’s [audio-stretch](https://github.com/dbry/audio-stretch) C library.

 The library gives very good results with speech recordings, especially with modest stretching at the ratio between 0.9 (10% slower) and 1.1 (10% faster). AudioStretchy is a Python wrapper around that library. The Python package also offers some additional, optional functionality: supports MP3 (in addition to WAV), and allows you to preform resampling.
