Boba-Mod is a modification of the Boba device created by Osprey Instruments. The device functions the same. Only the user interface has been changed, and an output gain knob has been added.
If you appreciate this device, please donate to the original developer on his Ko-fi page.

Description by the original developer
"Boba applies an FFT of an internal/external side-chain input to determine which frequency bin is above the threshold. The threshold itself is roughly weighted to pink noise, and can be shifted up or down using the "Thresh" dial. The difference between the actual level and threshold level is evaluated for a given frequency, then up to that amount of gain reduction can be applied to the carrier (main) signal when "Depth" is at 100%."
"The reduction is actually done with envelope followers on each frequency band, so the timing can be adjusted with the "Attack" and "Release" controls. There is also a 5-band EQ on the side-chain signal before the FFT so that you can emphasis the frequency you want to focus your reduction on by boosting, or conversely, deemphasis what you the frequencies you don't want to analyze but applying an EQ cut. This can be somewhat counterintuitive at first, but proves to be an effective control mechanism, as a boosted frequency is more likely to pass the threshold levels in that frequency region."
"Additionally, there you can switch between stereo mode (left/right) and mid-side mode, as well as tune the amount of stereo linking."
