Give a boost to your sound with this spectral shaper!

The algorithm's quite simple: Sample the average logarithm loudness on the freq domain, and apply a gaussian filter to smooth the curve. Then the original signal is interpolated to the dest signal in the freq domain.

Usage

• Strength: The main parameter.
• FFT Order: Set the FFT size.
• Pink: Add some tilt to the frequcency domain. This makes the sound more suitable for bus mixing.
• AGC: Compensate the loudness to match the original RMS of the window. Set to full by default.
• Soften: Make the sound softer. This is useful when processing something acoustic.

TODO

• The mac release is built on my M3 mac, so no guarantees for loading properly on x86 machines. If you are not able to load this, you can build one yourself.
• I planned to add oversampling but it seems not that useful at this period. So I removed it temporarily.
