SoX based audio file merge-n-splitter appropriate to resplit audio books.

Project description

What’s that

letmehear is a SoX based audio file merge-n-splitter appropriate to resplit audio books.

It is able to function both as a Python module and in command line mode.


  • Large variety of supported input audio formats (due to SoX).
  • Batch audio files processing (including recursive path traversing).
  • Adjustable output audio parts length.
  • Adjustable output audio speed.
  • Adjustable backshift length (number of seconds from the end of a previous audio part to place at the beginning of a next one).


letmehear depends upon SoX command line utility -

Ubuntu users may install the following SoX packages: sox, libsox-fmt-all.


  1. from letmehear import letmehear - if you want to use it as module. LetMe class is at your service.
  2. letmehear -h in command line - to get help on utility usage.

In the following example we merge all audio files into one, increase its playback speed to 1.2, and resplit it into chunks of 3 minutes, putting them into letmehear directory created inside /home/idlesign/audiobook_1/:

letmehear -s 1.2 /home/idlesign/audiobook_1/


Dedicated to legacy Mystery car audio system of mine unable to digest one and a half hour mp3 file with another Discworld novel %)
