Proposal pages help us get from feature requests into actual plans. This proposal page is about adding a way to select frequency ranges. It's particularly useful for cleaning certain kinds of noise/glitch and for changing the timbre of a sound.
Proposal pages are used on an ongoing basis by the Audacity development team and are open to edits from visitors to the wiki. They are a good way to get community feedback on a proposal.

  • Note: Proposals for Google Summer of Code projects are significantly different in structure, are submitted via Google's web app and may or may not have a corresponding proposal page.

Proposed Feature

On the spectrogram view, allow a region to be selected, not just a start and end time. Then do processing of only audio of that frequency range, for example making it quieter.

Developer backing

  • James Crook
  • Paul L

Use Cases

Cleaning up unwanted sound. Enhancing certain resonances, and changing the quality of a voice.



Current Status

Federico Miyara has a version of spectral editing in Audacity that can pick out arbitrary shapes:


Pual Licameli has this video of his modification to Audacity that can pick out rectangular regions.
