How to fix common audio issues when working with sound archives!

About this event

The following event is part of the 2021 SpokenWeb Sound Institute. For more information visit : https://spokenweb.ca/institutes/

This online workshop will teach participants how to clean up audio collections, using the Sound eXchange (SoX) command line tool. Known as the “swiss army knife of sound processing programs,” you can use SoX to analyze and edit audio files with simple text-based commands. We’ll start by getting comfortable with the command line environment, showing you how to navigate directories, create files, and load programs. Then, we will run through some basic SoX commands, including how to:

  • Play audio files
  • View metadata
  • Trim silence
  • Adjust volume
  • Filter noise
  • Visualize sound with a spectogram
  • Combine effects
  • Batch process multiple files

We will work with real audio files from the SpokenWeb archives, using examples of problems that you are likely to encounter when digitizing analog collections. You will also have a chance to test out what you have learned on your own files.
