Optimization Not Available

The "Optimize" feature is only available for Linear frequency scale.

Perceptual scales (Log, Mel, Bark) compress frequency information non-uniformly, making perfect reconstruction optimization incompatible with reasonable image dimensions.

To use optimization, please switch to Linear scale first.
