Octave stretch or compression

What follows is a comparison of compressed-octave 32edo tunings.

32edo
  • Step size: 37.500 ¢, octave size: 1200.00 ¢

Pure-octaves 32edo approximates all harmonics up to 16 within NNN ¢.

32et, 13-limit WE tuning
  • Step size: 37.481 ¢, octave size: NNN ¢

Compressing the octave of 32edo by around NNN ¢ results in improved primes NNN, but worse primes NNN. This approximates all harmonics up to 16 within NNN ¢. Its 13-limit WE tuning and 13-linut TE tuning both do this.

32et, 11-limit WE tuning
  • Step size: 37.453 ¢, octave size: NNN ¢

Compressing the octave of 32edo by around NNN ¢ results in improved primes NNN, but worse primes NNN. This approximates all harmonics up to 16 within NNN ¢. Its 11-limit WE tuning and 11-limit TE tuning both do this.

90ed7
  • Step size: NNN ¢, octave size: NNN ¢

Compressing the octave of 32edo by around NNN ¢ results in improved primes NNN, but worse primes NNN. This approximates all harmonics up to 16 within NNN ¢. If one wishes to use both of 32edo's mappings of the 5th harmonic simultaneously, this tuning is suited to that due to evenly sharing the error between them. The tuning 90ed7 does this.

133zpi

Compressing the octave of 32edo by around NNN ¢ results in improved primes NNN, but worse primes NNN. This approximates all harmonics up to 16 within NNN ¢. The tuning 133zpi does this.

Below is a plot of the Zeta function, showing how its peak (ie biggest absolute value) is shifted above 32, corresponding to a zeta tuning with octaves flattened to 1197.375 cents. This will improve the fifth, at the expense of the third.

Possible tunings to be used on each page

You can remove some of these or add more that aren't listed here; this section is pretty much just brainstorming.

(Used https://x31eq.com/temper-pyscript/net.html, used WE instead of TE cause it kept defaulting to WE and I kept not remembering to switch it)
