Is your feature request related to a problem? Please describe.

• Request to add F12 and F9 on top of F6 and F3 #284
• Request to add value for ERDI and SPDI #284
• Request to add scores for Directivity #287

Describe the solution you'd like

• Compute the various scores and add them to json files
• Expose some of the scores into
  • Large ranking tables
  • Add values into the speaker data page

Additional context
There are already some computed scores for DI but they are not exposed.

• spinorama/src/spinorama/compute_misc.py

Made some progress, F6->F12 are computed (I forgot F15 but will fix that).

That's awesome, thank you. Any chance to add DI to the spreadsheet?

[pierreaubert]

DI is coming. Question is what do you want? I have added the std dev of SPDI. Lets see if that got reasonable results first.

The simplest would probably be what VituixCAD does: ERDI SM and Slope, and SPDI SM and Slope, where SM is "Smoothness (r^2) in amplitude response based on a linear regression line through 100 Hz - 16 kHz" and Slope is "Slope of best fit linear regression line through 100 Hz - 16 kHz"
