Proposal pages help us get from feature requests into actual plans. This page is about enhancing and expanding the functionality of Audacity's Plot Spectrum command.
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 Features

  • Specify the min and max of the dB (y) axis
  • Compare spectra of different audio selections
    • Plot the difference between those two spectra
      • Send that difference to the Equalizer effect

Developer/QA Backing


Motivation/Use Cases

  • Compare the spectra of different recordings of the same performance and EQ one to sound the same as the other.
  • Compare the spectra of recordings of different performances recorded at different times or places and EQ them to sound similar. This would be for collecting these recordings on a CD release or compilation.
  • Possibly useful in audio analysis e.g. environmental noise.
  • Forum threads [here] and [here].

Some suggestions on Suggested_Frequency_Analysis_Capabilities might fit in with this proposal.
