FAC Bandit is a multiband audio effect that splits the audio signal into three bands of frequencies defined by adjustable crossover points. Each band is processed independently by its own effect processor and the outputs are then recombined to produce the final effect.

Each frequency range is altered with different effects and settings that won't sound the same if applied on the full frequency range. As you have probably realized, FAC Bandit is a wonderful and powerful sound design tool for designers who want to sculpt new personal, exciting and outstanding sounds. Either in a subtle way, without compromising the original tone, or in a more drastic way.

All of the FAC Apps Are Essential

I literally use at least one the FAC apps on every single track or bus. They sound clean, sharp and precise or as dirty as you want them to be. They are user friendly and dont max out the memory bandwidth.

The developer listens to us and understands the unique platform of ios production.

They are modestly priced and perform as good as any desktop vst.

Everyone will have this eventually

This will become a standard iOS music effect. Great bit-crush filter that is perfectly complemented by LO FLY DIRT. Those 2 apps are the foundation of your drum sound.

If you don’t buy this now you’ll probably pay more for it when you eventually do get it.

Excellent as always

Yet another pro quality auv3 from Mr. Corvest, this providing a unique way to separate your mix by frequency range, or c ft ryouIf you are attempting to make any kind of quality music using iOS, you owe it to yourself to add this and the other FAC effects to your arsenal. Peerless.
